Hello all, I stumbled upon this forum through google, and could use some help.
I was at work one day, and one of our wonderful TVs no longer lit up. I decided I'd take it home, figuring it was probably just a bad capacitor, and I would get a nice new TV up and running.
Long story short, I got the whole thing apart, and there are no bad capacitors as far as I can tell. I did test them, and all of them seem to work fine from what I can tell.
Here's the best way I can lay this out:
The TV is a Samsung T240HD (24", CCFL etc etc). I had the power supply out, and plugged everything together (I will get pretty ambitious at times)...
I tried out a pair of smaller lights from a 20" display, and at first, they did not light up at all, however after maybe 5 minutes or so, they lit up, much to my surprise, and stayed on, however even when I turned everything off and turned it back on, there was still a long delay before the lights came on.
Am I totally looking at a new board? I've seen them go for about $50, which for me, is totally reasonable, this TV cost me nothing so far, and is absolutely wonderful. If I can get it up and running, it will replace a big 30" CRT we've had for years that is pretty terrible.
I'm not circuitry expert, but I work at a computer shop doing all sorts of repairs, and I have repaired displays with bad capacitors, but when there are none, I'm unsure about where to go next.
Thanks in advance!
