Tv powers up but no picture. before it wuld take a few minutes to come on but now it doesn't?

Hi Michael,
The main board in your TV appears to be faulty. An experienced technician can repair it or change it.

You don't mention what type of TV it is. But from what you are saying, it's probably bad capacitors on the power supply board. In alot of cases it's easy to determine if the capacitors are bad by simply looking at them and if they are bulged at the top then all you need to do is replace them with the same values and your set should work again.

Normal problem. Cable connections are loose. Do this Unplug all the cables including the power on Wait for sometime - minute or more. Re connect all the cables. See that they are secured in the sockets properly. Switch on the power. Your picture problem should be over.

Hello! It sounds like there are a few things that could actually be going on. If you are getting no picture on the TV(you have a black, blue, or snowy screen), you will want to make sure that the TV is on the correct channel and/or input. You will want to be on channel 3 or 4, and possibly on a Video 1 or 2 or HDMI 1 or 2 input. If that doesn't work, then try unplugging the receiver from the power source for about 10 seconds. If you are still not getting a picture, let me know!

If you have a signal loss message on your screen (Signal has been lost, Partial SIgnal loss, COmplete signal loss, or Acquiring signal), you will first want to unplug the receiver from the power source for 10 seconds. You will get the Acquiring singla message as the receiver reboots after you plug it in, but that should only be about 5 minutes at the most. If you get the message after 5 minutes, you will want to make sure that all of the cables going from the back of the receiver to the wall are tight. If that still doesn't do it, please let me know!

hello,
Read my tips here, may can solve your problem.

Ur tv now power on only have picture few mins,than dead,have sound only?Yes,than the 1 or 2 the long board call the LCD inverter boards are dead.The LCD inverter long boards help the LCD screen to have a backlight to produced a picture.Tries websites like Shopjimmy.com,Ebay.com to buy 1 or 2 long LCD inverter boards for the replacement.

Look at the venting grills to see if you can see any white lights inside the set, if not, the backlight inverter board may have gone out or it is not getting the power from the main power supply sections.

This is very common in Samsung DLPs. The DMD board is going bad. You will need to replace it.

I have the same problem. The only way to get the TV to come on is to unplug it, but once you get it back on it turns itself off again in a few minutes.
