hi..It's probably a loose cable. The first one to check is the
green connection but make sure they're all tight. RCA cables
tend to pop out part way which is enough to stop the signal.
If the green signal is lost, you get no picture. If the red or blue
are lost, you get a picture with bad coloring.

If you still have the problem check this
LOOK in the back of the TV when you have it turned on. Look in the slots near the top for a white glow coming out of it.

IF you see it, you need your signal board replaced...

IF NOT, then you need your power supply board replaced...

Hi,

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

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

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

Hope I helped you.

Have a nice day!

Thanks for using Fixya.

This is the main fault, that most Sony LCD TVs. The actual cause is with a faulty T'Con board. For most Sony LCD sets, this part [T'Con board]; will be a built in part with its display panel, and can't be replaced. Display panel replacement is the only repair work. Nothing can be done, even for the authorized service center. If you wish to get some details; check the site linked here. Pull up older posts. Surf the site with patience.
