    Samsung LN-T4661F - Sometimes when I turn on the TV I get sound but no picture. The screen stays totally black. I leave it on for about 30 minutes, then turn it off and back on and the picture will usually come on. I called Samsung about this, but the phone rep said there was no info about a known problem. So, I reported the problem and will work with Samsung to get it fixed. I hate to have the TV fixed, because sometimes you wind up with worse problems. I like the picture, etc., of the Samsung, but I am fed up with this happening.

    I have the SAME issue with this TV. I'll turn it on, the picture shows for about a second, and then *poof* it's gone. I'm not sure if this is a coincidence or not, but I turned the TV on, hit the "menu" button on the remote the second I saw a picture and that seemed to fix it.

    Again maybe a coincidence but it's worked twice now...

    This is the 3rd time this has happened on my tv. It's about 18 months old and after not being on for a night or wkend .. come to turn on and sound, but no picture. We have extended warranty, so even though it fixed itself last time... I will not wait for this to happen again. Tomorrow I'll be at Best Buy......

    This has happened to my 2 year old Samsung LN-T4661F three times now. The 10 minute rule did not work, nor did somebody elses recommendation of turning the AC on during humid weather. After reading about other people's experiences, will definitely call Samsung and go back to PC Richard's where I purchased this TV. Lucky for me I got an extended warranty.

I think you have problems with the digital main PWB.

If the power PWB failed, turn off and change the pilot ligth to red.

Could be the signal board has a bad cap, in this case it sounds like you are getting intermitten power to the inverters....when the tv goes down and of course you have audio....Shine a flashlight on to screen and see if you have a picture...look carefully. If this is the have the above problem!

TV picture goes out after 10 minutes of viewing with popping sound

It can be a couple things. Something bad on the power board. Or the vertical output circuit. How long ago did you purchase the television. Your best course of action is to have it serviced.
If you need any information or other assistance let me know.

I have a Philips Plasma tv 42pf5321d/37 with sound but no picture

Thats the great sound of Exploding capacitors on either the power supply board. or another one in there. Now the set is in fault protection. It tried to warn you with the RED blinking LED that there was something amiss by shutting itself down. When you unplugged you reset the error and allowed it to do it again.

Best Regards and Smper Fi

Sony kv35s66: No picture, just sound and red blinking

This should be a quick fix. Try resoldering the vertical IC. This is a small flat IC attached to a heat sink with about 11 pins. It should be marked LA7837 or something similar. That should resolve the problem.

Keep us posted.

TV Picture Goes Black

I had the same exact problem.
I removed the bulb and cleaned it. There is a small screen at the top of the bulb and it was covered with dust. Once it was cleaned I replaced the bulb and it solved the problem.
Thanks to those who posted the solutions
