Repair to LG TV
Discussion
I have a 50" plasma LG television, my computer names it as the 50PC55-1, its slightly over 6 years old and it has difficulty switching on. It started off needing to be switched on/switched off/and then back on again to get a picture, otherwise it would be just a black screen although the sound would work.
More recently I have to do this six to ten times to get the picture to come on, although if the room is warm it comes on a lot easier, sometimes straight away. A quick google suggests it either the Y or Z sustain board that is faulty and quite common on LG TVs.
Whats the best thing to do, either board is about £100 and although I think its probably the Y board if I'm wrong its money down the drain that could go towards a new TV. But its such a shame to just bin it as the picture is excellent when it switches on and once its up and running is faultless, indeed I'm typing this on it now.
I know I could just put up with it but I hate titting about, its like when I go round to a friends house and use their laptop, they are quite happy to wait for 20 minutes for IE to load in where as it drives me up the wall.

Pretty sure the only person who can help you is yourself really. To be blunt, it's your money and your decision on whether you take a punt spending a 100 quid or so trying to repair it. If it works, you save yourself hundreds as decent 50 inchers are not too cheap. On the other hand, you could change both boards and then find out it's something totally different! IMO, pass it onto a TV Tech and let them do a diagnosis then go from there.
Onlt thing I would check out is the average life-span of the screen, as being a plasma it will need a re-charge at some point.

If it were me (and to be fair I'm an electronics engineer) I would take the back off and look for any bulging capacitors on the power supply. 90% of flat screen TV faults I have seen have been ageing capacitors which lose their capacitance over the years. When this happens they bulge noticeably. Call local TV repair chap, see if he will have a look for a modest fee. These capacitors aren't exotic items to source.
This happened to a couple of mates of mine a few years back 50" LG screen.
Y sus board fitted £329!!!!!!!!!! its only an LG and a new one can be picked up for not much more.
The second mate said tv just went bang so i took the back off and found 4 capacitors bulged up. No other damage. I replaced the caps and tested TV guess what BANG!!
My advice if its over 5 yrs old get a new one. Unless its a pioneer i wouldn't bother repairing it due to the cost of part and what new TVs cost now.
- The first one said black screen and sound

I had this problem with a 50" LG Plasma (50PK350), I failed to find anywhere that stocked a replacement power board, I inspected the resistors which seemed fine, I resoldered a few pieces on the back which rumoured to solve the issue - nothing.
I ordered the replacement resistors but after reading up on it, the chances of them failing again are pretty high. Instead I replaced with a Samsung 55F6500. I got John Lewis to price match it down to £1,060.00 with 5 year guarantee.
Despite it being approx £200 more than I wanted to spend, I am delighted with my purchase

I will probably knock the repair on the head and get a new TV. I am edging towards a smart TV, I do have a (power hungry) PC connected to it at the moment but if I am just watching stored films etc I could use the smart feature instead of turning on the PC. My films are stored in .mkv format as this is what my bedroom TV (toshiba) plays.
Out of these ones which do you think is more likely to play them and which is the better TV.

Our current TV cost me £1.99 in parts and has now been going for 2 years.Morningside said:
