A friend of mine sold me his non functional Panasonic TC-P50U2 as is. The TV occasionally work when powered on, but most of the time the set would power on for a couple seconds, and then blink the light once (and repeating that indefinitely).
Based on the service manual I've seen, this code means the A board needs to be replaced. However I can't get over the fact that the TV does in fact decide to work every so often (albeit rarely) which tells me that a single component may be on the edge of failure.
Are there any tests I should try to locate a failed/failing component on the board? I'm no stranger to electronics and around a decade ago I used to work in TV repair, but rarely at the component level. I'm excellent with a soldering iron and have access to quite a bit of electrical engineering equipment (and a couple electrical engineers) if it comes down to it.

I am new to this forum but not new to forum world. I come from Automotive end of side which is my main passion in life. Give the automotive nature, I love fixing and restoring things and I have in the past fixed many simple electronics, soldering, etc.. but this is a bit more involved so I found this forum, and I am very glad I did.
