Sound but no picture on Philips 42pf9731d/37

Hey folks, this is a new one to me. I was recently able to fix my LCD TV that was stuck in standby mode but now have the problem of no picture but sound on a different TV listed above. Would blown capacitors cause this like before or is this something completely different. I remember hearing about a Zener Diode that might fix the problem but haven't looked into it. (the TV in question is a friend's and I can't take a look at it since she lives 7 hours away, lol.)
Anyhow, she said her son went to turn down the volume and the picture quit.
I spent $5 to fix my TV and was hoping I could fix hers for as little as possible also, thanks in advance for info I don't know, lol.---ahltru

    I have same problem with my Aquos 42 inch stuck in stand by. Sears came out and replaced all 3 boards @ 500.00 a piece then gave up and bought me a new TV. I still have the old TV, how do you get it out of standby mode?

I had almost the exact same model. Mine was a 9631D, built on the same architecture I believe. I can say, if you heard a POP noise, before the picture went out...You are most likely looking at your Y-SUSTAIN, and Z-SUSTAIN boards. Don't let this get you down. Look closely for any blown caps. And You can not only replace one board. unless it's the Z. If you only get the Y, without the Z, or vice versa, you can damage the new board, and end up in the beginning scenario.

Hope I helped,

Adam

37" Philips LCD sound but no picture


Check the inverter on the sides of the TV. This sounds like the inverter is going bad and that's the reason why you have sound but not picture.

26PF8946/37 Red light


Hey habo,

The red light you are referring to most likely is the power indicator light. On many newer TV's this light will appear red when the TV is off or in "standby" mode, and green when the TV is in operation.

Please keep in mind that some TV models may use the power indicator light to notify owners of ay potential hardware problems as well, so you may wish to refer to your owner's manual documentation if you have been encountering any problems during TV operation.

Hope this helps you out.

Sincerely,
Aaron

Rest the tv by unplugging it from the wall for a hour. If the picture is still gone replace the small signal board.

Philips plasma 42pf5520d pictures has gone?


My Philips Plasma TV model 42PF7220A/37 went into "no menu exit" mode on 11/28/2007. I went to www.usasupport.philips.com and downloaded an upgrade. Just followed the instructions and my TV is all better.
