Hello one and all in forum land.
Have a bit of a problem with a mates telly. He bought it off ebay with a faulty power board and asked me to fit a new one. One sjs order later and the transplant compleate the problem was still there. What was happening was when you turn the TV on the stanby light would flash white and a relay would click and then the light would go back to red again. The screen did absolutly nothing. After scouring the treads I unplugged the YSUS board and tried to turn the tv back on and it worked. In as much as the TV came out of standby and stayed on. Obviously the screen is still blank. I have pulled the board out to look for anything obvious but can see anything and I have come to the end of my limited PCB faultfinding knowlage. The YSUS board is a 6871QYH053B. Now befor I go and splash out £100+ on a new YSUS board on his behalf (Unless anyone can recomend anyware to get a cheaper one) Is there anything I can do to prove that the board is definatly faulty. My mate is a little concerned to splash out on a board and find its somthing else. My test equipment is limited to a Multimeter and a naked eye (stop laughing at the back). I am an electrican by trade and have limited experiance with component level fault tracking so any help would be gratefully accepted.
Many Thanks

welcome to the world of plasma fixing its hard to be sure all the time which board is at fault some time you just have to suck it and see from what you have done theres a fair chance its the ysus but you can never be 100% sure
i am sure most of us have replaced a pcb and found either its no better or its cured that fault but now there is another
good luck
and i hope he did not pay to much for the set i the first place

Yes it's going to be an interesting and sharp learning curve. He only paid £40 for the set and I don't think he is going to be too hard done by if I can get it running. He has adhere to buy a new ysus board but I am having a lot of trouble finding one. I have tried SjS and a few other sites but they are all out of stock and the only one on eBay is a bit suspect seeing it came out of a tv with a similar fault. Any one have any suggestions on where to look.

Update....
Been offered a board out of a plasma that had a nasty accident with a wii remote. Now this is probably a very silly question but would the screen have caused the board to blow or should it be okay. The current tv comes on has sound but no picture due to a wii shaped hole.
Thanks in advance

Okay back to the drawing board. I can not find a ysus board anywhere. Not even eBay and every where else is out of stock. Please if anyone knows where I can get on from please can you let me know.
Thanks
