Toshiba 50 inch Projection TV Model 50H82

Introduction

Practice you accept large screen projection TV that y'all want to become rid off? This instruction will requite y'all a guide on how to suspension down and disassemble a projection TV into manageable pieces for disposal at a dump or landfill where the pieces and components can cleaved downwards further and have a take a chance for recycling.

This article with photographs uses a Toshiba 50H82, a 50 inch projection Tv as a model. This Boob tube had picture quality bug and repairs would price almost the price of mod flat screen TVs. Large projection TVs are beefy and heavy. Getting rid of them can be expensive considering the new High Definition TVs (HDTV) are cheap and nobody wants the massive projection TVs anymore. These beasts take up too much space. (Come across Fig 1)

Dismantling Tv Overview

In my opinion, breaking down the Toshiba was not difficult. The design was user friendly for internal access. However, the case around the master components was glued. But I have a solution for destruction.

The TVs of today that uses LCD or LED technology are very lightweight. Even though I purchased a 50 inch LED Television with someone to help me, I really didn't need the assistance. The box is large merely there were two straps to handle and deport the box. I am non that strong just I was able to elevator the box and move it effectually by myself without any problems.

Older Television receiver employ cathode ray tubes (CRT) to provide video and there have been large CRT TVs made to provide screen sizes up to 36 inches. However, newer engineering science came around to support even larger screen sizes to provide a big screen movie experience. 1 of the technologies that became popular during the late 90'due south to early on 2000'southward, were the Project TVs. There were ii types of projection TVs in the market: front and rear. A rear projection Idiot box looks more similar a standard goggle box.

The rear projection TV contains a ruby-red, green, and blue (RGB) projector, which produces the images to the back of the TV. This projector can exist CRT, LCD, or DLP. The Toshiba 50H82 model uses CRT projectors. The back of the TV contains a mirror, which receives the flick which combines the RGB colors into any color from the original picture source (from cable, satellite, disc, and then on). The prototype that is projected to the rear mirror is what the viewer sees in the front screen.

Training

Showtime, move the projection TV to a place where you can go muddied and make a mess. I used the living room at first to just remove all the heavy parts prior to moving it to a final disassembly expanse. In this instance, I used my garage.

Gather all the tools needed to open up the example and remove components like big circuit boards. In the Toshiba 50H82, there were lots of modest slotted lag screws. I used a cordless drill with an attachment to remove them.

Be mindful of any loose parts like screws or droppings flying from using brute force during your work.

Remove Back Panel

I started the work behind the TV. There is a panel to access the large main circuit board. Unscrew the bolts or screws and remove the panel. (Come across Fig ii)

Fig 2. Removing the Back Panel — Fig ii. Removing the Back Panel

Disconnect Ability Cord

In that location is a power cord connection that was not accessible with the back panel in the way. With the back console removed, you can come across that the power cordis connected to the chief lath. Disconnect to get the cord out of the way. (See Fig iii)

Loosen Main Printed Circuit Board (PCB)

Locate any screws that fasten the main lath to the base of the Television receiver. Unscrew all of them until you find that the primary board is loose. Once the board is loose, you lot tin can starting time disconnecting all the wires. (Run across Fig 4)

Disconnect Whatsoever Cables and Wires from PCB

Note in the pictures (Fig 5a and 5b) that at that place are several cables and wires connected to the master board. You can just cutting them with wire cutters or scissor or disconnect by mitt. I started disconnection by hand in case someone wanted to put the TV together again. After running into some connectors that seem incommunicable to remove, I just outright cut them.

I imaging some scavenger trying to put this TV together so I thought I would make it easy to put back together. Unfortunately, the connectors were and then stuck and I was running out of patience.

Put PCB Aside

After separating the cables from board, you can put it aside to work on the next stride. (See Fig 6) Equally yous can encounter it is quite large for a PCB.

Remove Front Panel

For the next pace, I opened up the front bottom panel. I had the pry this comprehend from the side with a screwdriver. Once I got one surface area loose, I was able to work my way in separating the panel from the TV. (Come across Fig 7)

Removing Middle Console

There was another panel in the center to access the RGB projectors. Unscrew and remove this comprehend and expose the projection system and associated excursion boards. (Come across Fig 8a and 8b)

Remove Front Screen Part 1

Nosotros will need to remove the RGB projectors from the top. Still, the large front screen is in the manner and has to be removed. Ensure the large plastic slice holding the screen is unscrewed from the lesser.

This large screen slides up for removal. There are four 'hooks" that concord the screen in place. (Run into Fig 9)

Remove Front end Screen Function 2

Take hold of the plastic slice from the bottom and lift upwardly. The large screen is bulky but non heavy. Put the screen aside and out of the way. You will come across a huge surface area for the project of epitome going onto a big mirror on the inner back of the Boob tube. (See Fig ten)

Unscrew RGB Projector

Locate the screws that are property the Ruby-red Greenish Blue (RGB) projector associates from the acme. (Meet Fig xi) Unscrew the project arrangement and ensure no wires are continued to the remainder of the TV. If in that location are whatsoever connected wires, detach or cut.

Fig 11. Location of Screws Holding Projection Assembly — Fig 11. Location of Screws Holding Projection Associates

Remove RGB Projector Assembly

The RGB projector assembly was the heaviest piece other than the large TV body. (Encounter Fig 12) Put this piece in a box because there are many sharp edges that could hurt yous. Put the box and the projector associates out of the way.

Remove Speakers

The left and right speakers are held with 4 screws each side. Remove the speakers to lighten the TV. (Fig 12.5)

Slap-up the Housing

Fifty-fifty with the master circuit board, forepart screen, RGB projection associates and speakers removed, the hollowed out Television receiver is still heavy and very bulky to put in a small truck. Even so, the TV is lighter for moving. Yous can at present put the large Television set in a big truck or van and become rid of it.

Y'all now accept the option of disassembling the TV body even further to send the pieces in a small SUV or car.

The trouble with the rest of the Toshiba 50H82 Television set is that there are no other areas to unscrew. The remaining pieces are glued together. Brute force will be needed to break the residual merely there is a big drinking glass mirror to bargain with.

The mirror slides out up merely the top of the Television receiver is glued and in the way. I took a large heavy duty hammer to dissever the left and correct sides from the Tv. The hammer I used is not the blazon used for removing nails on the other side of the tool. That hammer is besides weak. I used the hammer akin to a pocket-sized sledgehammer like the one Thor uses. (See Fig 13)

Remove Mirrow

Later removing the top, I was able to slide the large mirror out and put information technology aside. (Encounter Fig 14)

Warning: This is glass. Exist cautious when handling!

Breaking Housing Downwards Even More than

I started removing the left side and right side with the hammer. After removing a few more odd particleboard pieces, all that was left is a piece that looks similar a cabinet or table on wheels. (See Figures 15 and 16)

Recycling Ideas

After making the large wooden pieces small enough to fit in your van or truck, you lot can neatly stack the pieces in the vehicle and transport to your local landfill.

If you lot desire, the particleboard scrap wood can be reused for making furniture. The husk of the TV's cabinet tin can exist converted to a table or cabinet for the new Goggle box.

Epilogue

The Toshiba 50H82 50 inch rear projection TV has sentimental value. I purchased this TV around 2002 later on my second kid was born and I knew I would be at habitation more to care for them. Having big high definition TV made entertaining kids and guests more fun.

Ten years later, the video started to go fuzzy. I was non able to play any console games similar Nintendo Wii and Xbox 360 anymore. It would cost approximately $100 dollars just to have a technician simply to come up to the firm to troubleshoot.

Leaving this goliath Tv on the curb is just an eyesore. With HDTVs relatively inexpensive, why would anyone want an erstwhile project TV that does not work correctly?

Cheerio, Big Screen Projection Television. Yous served a purpose well merely newer applied science has taken over. I mean some new TVs do not even carry the old RCA component or S-Video connectors anymore. HDMI connectors have taken over. Makes me wonder what the next ten years will bring with regards to telly tech.

YES! Exact TV was given to me 10 years ago, and now no longer functions. Taking it autonomously today. Thanks for this! Interesting that i may get a new TV stand for my HDTV.

Bob on March 06, 2020:

Thank you! I had the exact aforementioned brand and model that had to come up out of a basement subsequently 18 years. Your guidance was very helpful!

Cooled past a liquid? They must have some really adept seal to foreclose leaking and evaporation.

John on January 11, 2020:

My Hitachi 57 inch was still working fine simply was getting fuzzy after 16 years. I suspected it had dust inside somewhere. Turns out after tearing it apart It had dust on the lenses that I could have cleaned off had I known how to properly disasemble it. I salvaged a few parts I'm certain I don't need similar the projector lenses. I idea it was interesting that the lamps were cooled past a liquid and in that location was a rubber float on the side of the heat sink housing to permit for expansion and wrinkle of the liquid. It was a realy practiced tv and served me well except for damaging my shoulder while moving it most 12 years ago.

Thanks soooo much! I've been trying to button this 65" piece of Sony "piece of furniture" effectually in this room, knowing full well that there was no way to get it out in one piece. (Information technology took three delivery men, back around the late '90s, to get it in the house. And, they dropped the kickoff 1 off the porch, had to go dorsum and get another one, and one of them injured his back getting it in. I'm solitary with this monster now, and I'yard a 70 year old woman. However, I do some carpentry, haul and shovel stone, pull up fences, and clear cut wielding a 40 pound saw. I'm 5'iii" tall and counterbalance 110 lbs, and my "opponent" weighs in at effectually 300lbs., is an inch or 2 taller than me, and is 65" wide. Now, thank you to y'all, I might very well go information technology out of here before they bring the new one!

Thanks again
