KDL-46V3000 "Just a green light"

[amoparx]

Hi All,
I have a Bravia KDL-46V3000. 2/2008. For the last 9 months or so, when I turn on the TV all I get is a solid green light. Basically, doesn't turn on. (dark screen, no sound) I shut it off and back on a number of times and it will finally turn on. Other than a couple vertical lines (had for almost 3 years) the TV works perfectly fine. (but that's another issue) I started to just leave the tv on since it was so hard to turn on. A week ago, I accidently turned it off. It had been on for about 2 weeks. Prior to this, If I left it on, it was just for a day or two. It will not turn on anymore. I replaced the power supply board with no luck. I've checked all connections. Any ideas?
Thanks in advance!

Apparently this isn't something that happens often? I've searched for the last few days and can't find anyone else with the same problem.

Could be bad caps on the power supply.
Please post pictures using manage attachments. Close, well focused are needed.

I replaced the power supply with a known good one. This is the only thing I've replaced. The caps look fine otherwise.

It's sounding like a typical Sony main board issue. They don't normally have many cap or PSU issues; mostly main board issues and panel issues (that's probably the other issue you're experiencing ). Did you try turning it on using the remote and by using the power button on the TV?

Yes, I've tried both ways. I did read somewhere that the main board kind of controls the second half of the power supply? Not knowing anything, The, main board was my next "guess" Thanks for the reply. I have heard a lot about the panel problem. I've put up with it for 3 years now. I'm use to it. It hasn't gotten much worse. The lines I have are right at the edge of the blacked out area when you don't have a full screen. So I don't see it all the time.

Well, so much for the "new" main board I bought off ebay. A cap fell off when I pulled the clearly "used" board out of the box. Now I'm responsible for the price of shipping it back. They said 10 available. Kind of makes you believe they're new. The way the cap was soldered on, I'm guessing it would be hard to reattach.

I got another "Main" board today off ebay. The TV works fine now!
