Hi,
Unplug tv from AC wall socket for couple of minutes, replug back in and turn it On.
If tv still does not show picture and wont stay On then its internal circuit problem of tv and most probably power supply or back light inverter board got defective for some reason. Local tv repair shop will replace defective board for you.
Hope this info will help you.
Thanks.

I am suffering from the same problem. When I turn on I get sound but no picture, although I do get the backlight coming on when I turn it on, I then get about 1/2 a second of picture then nothing. Even if I select TV specific functions such as the menu, I get no menu screen come up.
Any ideas out there?

My Magnavox plasma screen tv, model number: 42MF237S/37 makes a clicking sound when I try to turn it on. No sounds, no picture, just the clicking noise. Things I have tried so far: 1) Turning the TV off...


You either have a cold solder joint in your horizontal deflection circuits or your or in your horizontal output circuit. please be careful due to the fly-back transformer still holds power even unplugged until you discharge it.( ground it out). Hope this helps.

I have a Philips 30PF9946D/37 no picture


what you have is a bad inverter transformer on the inverter board. I nashed my teeth on this problem for a long time because no diagram is avail. Here's the fix for you:

Remove the invertor board. Take an Ohm meter and measure the outer 4 legs of each transformer. Between pins 1 and 4 (side with the white dot near leg 1) you should read .3 ohms. This side is usually good. Between pins 5 and 8 you should read approx 1.8 to 1.9Kohms. ANYTHING above that is a defective transformer. I'm sorry I do not have the part number for this, I've just been using an old board from a set with a cracked panel. If I can find a part number I will try to post. You can try Encompass parts on the web, they may be able to supply part number and transformer with location number.

When I turn on my TV it goes straight to the menu screen. You can still hear sound but no picture.

Even if I try to use the functions in the menu screen it flashes right back to the main menu screen. Very frustrated...need help!
