SOURCE: Vizio GV42L LCD TV screen black when turn TV on first time

If you are using a set top box this might be caused by turnig the box on at the same tie as you turn the tv on or slightly after you turn the tv on.  If you are using compnent or HDMI inputs the set needs to see the signal as it is turned on to know what formt the signal is in.

SOURCE: 50" Samsung Plasma with black screen

I had the same problem and had the TV serviced and found that the y board was blown $350 total. The repair guy explained that the board has a hot transister underneath that slowly leaked onto the board, but says that they can not get Samsung to admit to the problem. Works fine now but only have a 90 day warrenty on the parts.

SOURCE: 26" Samsung flatscreen LCD doesn't power up

Just to be a little more detailed, since I just fixed this problem. It is the capacitors are the problem. However, I think that if you have some minimal skills with soldering, you can fix this yourself. You just need to take out the system board, then the power supply parts are on the top right. The bad capacitor(s) will be bulging at the top and possibly have some brown stuff coming out. The ones that go bad are 1000microfarad, 10V, however you can replace them with higher voltage. I got 35V caps from radio shack for 1.59 each. You just need to solder out the bad ones and then put the new ones in and solder. Remember that the negative end goes on the side with the bold black part of the circle on the system board. Then just cut off the extra ends of the capacitors. If you are capable of doing this yourself, you will spend at most 6 dollars instead of however much a technician costs.

The set will need to be properly diagnosed to narrow down the problem. You could be looking at a bad inverter, bad CCFL lamp, fault in power supply or main board.

The backlight inverter which is also part of the power supply needs to be replaced. If you feel comfortable you can replace the blown capacitors on it.

When tv turned on will get apicture for only a few seconds then screen goes black, but wil continue to have audio. Cannot pull up menu on tv either


Hello.The screen goes black means that the backlights of your LCD is not working.Maybe the problem is the power supply or the driver board of the backlights.They shutdown because there have a shorted parts on the circuit or power supply. Did you try to reset the power and turned on and get a picture or every time that you reset the power it will get a picture and the picture goes black?

This does not seem to be a power supply issue but rather an issue with the backlight inverter board. When the screen goes black, take a flash light and focus it on the screen from a close distance and several angles. See if you notice a very faint image. Try changing the channels to make it more noticeable. Try it and let me know
