LG AP-42SA41 PLASMA TV

Hi,
You need to replace Y main board & buffer, which will cost you around $600-700. Since the TV is five years it will be better to go with new, and it won't be worth enough to spend $700 for old TV.

Hope this helps.

I am definitely a girl explaining this because I don't know the correct parts of the tv. Here goes. We had the same problem last year, called philips they advised I do a software update on the tv because that fixes everything....wrong. The light still flashed and no picture. I called them back and they said I had to find a philips tv repair to take it into....got lucky because there was one close by. Come to find out it was some board inside that cost $400 to repair. I thought cool it's cheaper than a new tv! Worked great until about 2 weeks ago the tv turns on and the light is green and picture pops up a minute later. Oh boy more problems! As I sit here right now my tv no longer has a picture. The green light is on but nothing. It's funny because we had it repaired this time last year. I'm fed up and buying a new tv!

this is not a Zebra printer issue.

Hello,

Your power supply board is dead, u know basic electronics’ and soldering? Most of the times, the power supply board just have dead leakages gases capacitors.These capacitors always bulges up on it top,or puff up on it top.Replaced these gases leakages capacitors will get your TV power stable,and work again.Or tries websites like Shopjimmy.com,Ebay.com to buy a whole refurbish power supply board for the replacement.
hope this helps...
