TV repair.....
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 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...

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

So true Peter, but in most households these days anything that stops or needs repair normally ends up at the tip or recycling centre as they are now called, the other problem is the diagnostics of certain things, the TV seemed straight forward after a lot of searching (you tube) and reading a few snippets. Similar to the sealed unit you mention, the two things on the PCB that failed are now obsolete which is a ball ache as these are probably the easiest bits to change on the whole board apart from the capacitors.............

In my expensive alternator headache it was a clunky end bearing. Mind you, getting the two halves of the casing apart wasn't that easy either! The bearings were standard sizes but roll sealed in. Once you machine away the rolled-over seal there was nothing to prevent the new bearings from coming out. So I had to ........ anyway, after the machined retainer plate and 3x new threaded holes and...... and.... I considered that I'd have been better off buying a new one! There's no exchange units anymore, like the old LUCAS B90 exchange unit scheme! The good news is that the rebuilt unit was still going strong when I sold the 16 valve Golf GTi a cuple of years later. Incidentally, it was my old Army pal, Bruce Gorton from Invercargill who talked me through how to do the alternator fix. I repeated the same trick in a later VW winder motor but used bronze bushes.
I'm sure a lot of these fixes will die out with our (?) generation. Any Kiwis remember Bruce Gorton. Ans wile we're here, remember KimW another ex RNZEME forumer. Great bloke
