TV repair.....

[bigduke6]

Recently the TV give out a crackle and pop then the screen went blank but still had sound, although its old, ten years now but its a plasma 50" and in HD the picture is striking.

As with anything now I just type in to google and all the info was at the fingertips, with the symptoms it was either a buffer board or the YSUS board (Y sustain board).

With the back off (nearly a million screws to remove) removed the buffer board and tested for any short and all was ok, the culprit looked like the YSUS board but it was going to be £50 and still had doubts, a quick test is on two main components (IPM module which are covered by a heat sink shield) with the sound it made when the screen went blank this was one thing which was pointed out on the net to test, simple test is with on the TV powered up and check for heat on the heat sink..... it was stone cold compared to the XSUS board.

Ordered the part but didn't realise it was coming from China..... (it was a used but good) ??? so it eventually arrived today, fitted this and did a temp repair on the buffer board as I snapped the clip which holds the main connections from the screen (these are like thin plastic foil with the wires running through), it powers the screen, gaffer tape and one of my daughters hair clips finally did the job of holding the original clip in place.

So with a click on the remote....... My TV is back up and running.

Had my doubts but more than happy, as it was a gamble to buy the part or new TV, they are cheap enough now but I don't think you can beat the picture on a plasma, just a shame most manufactures have stopped producing them.

Must state there is still Danger of a shock, my testing of the part with power on and the cover off was with a heat gun (Infrared Digital Temperature Thermometer Gun), I would advise if anyone is contemplating such repair, to seek advise if unsure and not complacent with a multi meter.

I've been waiting for years for my (1980s?) KTV color TV with 13 inch CRT to crap out so I can buy a flat screen, but it refuses to die. I have it over my computer monitor to compete for my attention. Resolution is poor but color is great. Have to pass the digital satellite signal through an old Sylvania VCR to convert it to analog so the KTV comprehends. Gotta respect a survivor, will keep feeding it electrons until it passes on from natural causes.

Yes good work Bigduke, many would have said to just bin it and buy another. But now you have the satisfaction of repairing it yourself, saving some cash and preventing another item of e waste going to landfill.

Peter, I hope Kiwi ingenuity won't disappear anytime soon. It's something we used to share with a number of other societies where spare parts are/were either expensive, hard to find or would take along time to arrive and necessity being the mother of invention and all that, we learnt to make do. I guess it's what is commonly called the No 8 wire mentality.

I wouldn't have a clue Doug, but if there is info on the internet or youtube then there is a chance.

My son fixed his plasma TV by looking at You-Tube videos. IIRC it cost him less than $70 US...

Russ, its where most of my info come from, Its like someone I know who runs a shop for car spares and accessories says " You can repair anything, the info is out there, its just finding it"

Congrats on the Save, bd6!

One of the (many) things about which I am a bit sad.

When I finally decided to make the jump a several years ago to a "big" flat screen TV, my research pointed to a particular make/model plasma TV set, but the key was to get it on sale. Yes, I work a being frugal.

As the after Christmas/New Year sales were drying up, that set failed to show ... so I opted for my 2nd choice, a like-size LED.

One week after the purchase, guess what popped up in a unexpected last gasp sale. {sigh}

I figured that I would have to wait a few years and then upgrade ... and then the plasma sets just ... disappeared.

Ah, Life ...

The problems start when you're doing mechanical stuff where something is a roll-sealed unit - such as an expensive but internally simple internal fault with a alternator or window winder motor. Plug in electronic units are simplicity itself - if you can get them. Just my take on these things
