TV Repair

[BillyCarpenter]

There's a rent all store across the street from my business. He rents heavy equipment and tools and everything in-between. Anyway, he's also a customer of mine for a few years. I was over there last week and he had gone to an auction and bought 2 pallets of flat screen TV's still in the box. Brand new. They still had the plastic on the screen. But none of them worked. He told me that he didn't have time to mess with 'em and that I could have 'em.


Over the weekend, I upboxed every last one and tested. I'd say it was about 20 TV's. 15 had a cracked or busted screen. It would cost more to repair than to buy a new one. The other 5 are repairable, I think. I used to work on TV's a lot back in the day. I'm talking about the CRT TV's with the flyback transformer and the HOT (Horizontal Output Transistor). This is my first time cracking open a flat screen. There's not much to 'em. 3 boards. 4 on some brands. You can easily find used boards on EBAY.

I've ordered the parts that I need. We'll see how it turns out. I don't know what to do with the busted TVs. Probably haul 'me to the dump.

Re: TV Repair

All the best with these. Let us know how they turn out.
What will you with those you are able to repair successfully, sell on eBay?

Re: TV Repair

I have one of the TV's playing perfectly. It's a 55" Onn. All I did was reseat all the connectors, do a factory reset and buy a remote. It's a ROKU TV so walmart had it in stock.

Re: TV Repair

I used to repair these,



We had one back with a note "catches fire" It got bought over to me with about 6 other technicians wanting to see if it did.
Plugged in and a small fire started in the neck of the crt tube, fortunately I only replaced one tube while I was there, much preferred repairing laptops since the voltages are a lot less.

I learned that there are Northern Hemisphere tubes and southern, they are different part numbers.

Re: TV Repair

After repairing a coupe of the TV's, I decided to add them to the game room. Now there are 4 TV's hanging on the wall and then I have 3 more TV's in the victual pinball machine. And one more in the electronic dart board.


Here's the problem. Several of the TV's are Vizio and use the same remote. Even some of the other brands use a remote that are on the same frequency. This creates a terrible problem with the remotes interfering with other TV's. There is no real solution. However, I did find something that works. You can take a piece of black tape and poke a hole in it and place it over the IR emitter. This way you have to point the remote directly towards the TV that you want to change. It keeps the IR light from spreading out all over the room.
