Having problems with your Flat Panel Televisions ?

I have a RCA L26WD26D Flat Screen TV. When you turn it on it will say "please wait". This lasts for 30 seconds or so. Then that goes off and the screen turns black with some sections turning white. It will vary the back and white and will stay like this for maybe 20 minutes. Then it will start showing vertical colored lines. They will change also and eventually turn back to black and white. After leaving the TV on for about 5 or 6 hours, the picture finally shows up and looks fine. So now I'm af

Hi coefremont,
\015\012\015\012

This is an indication of out-of-regulation in the power supply section. The very\015\012common caused of this fault is the leaky\015\012electrolytic capacitor in\015\012that section. It will drop the supply from normal voltage and\015\012will disable the unit.It needs a little warm-up to make itself stable but the\015\012symptom will get worst like what you've experienced right now. Sometimes it has a bulged/dome at the top but not all, it is better\015\012that you have a capacitor\015\012checker/tester to determine\015\012its condition. Your unit will back to normal again if the leaky capacitor is\015\012isolated.
\015\012\015\012

If you don't have necessary tools\015\012and test instruments, and can't do the job yourself, I would advice you to\015\012look for a professional to troubleshoot the problem. Don't\015\012attempt to work in the power supply if you don't know the safety precaution of handling it, there some stored\015\012electricity enough to hurt you with a little mistake only.
\015\012\015\012

Also check if your unit is under warranty /extended warranty,\015\012avail it because the manufacturer of your unit will fix it for free. Don't open\015\012the back panel, this will void the warranty.
\015\012\015\012

Hope I helped you.
\015\012\015\012

Have a nice day!

Vizio GV47L...when i turn on the tv, the screen stays black. The vizio light turns white and it makes the click noise like normal but after a minute of it doing nothing the light turns back to amber. I can turn it on and off using my remote. I read other problems where people had to unplug there tv to turn it off. Mine will turn off. Would the problem be the power supply or the motherboard. The slave inverter was making a squeeling noise and i replaced it like 2 months ago.
