The most likely the TV has a power supply related problem. It maybe a blown fuse inside the TV.
I can't say it's 100% the problem because I can't actually look at the tv over the internet.
If by chance the TV is still under warranty, go that route.
If not under warranty and If you have some electronic experience, you can purchase a Service Manual over the internet and diagnose the source of the problem and fix it by soldering in the new part. The Service Manual will give you circuit diagrams, test points, and part# lists. Usually, cost under $20.

I hope I shed some light on the subject for you.

SOURCE: im not sure if the power supply is bad or not... I

It appears like the 5VDC is low from the power supply adapter. This voltage becomes low due to defective capacitors inside the power supply.

Sony bravia kdl55hx729 3d led tv turns on 3 seconds shows picture than four red flashes


Hello,
the error light sequence that you are seeing is indicating a "backlight error". Most likely you have a bad inverter board -the board that powers up the back-lights behind the display panel. They might be available via ebay if you are a DIYer, or you need to call for sony service.
Good Luck!

When I turn on my set, light turns green, then after 30 seconds turns red won't come on


Sounds like there is a problem with the power supply. Try unplugging the T.V. and hold the power button for 30 seconds. Plug the T.V. back in and see if that helps. If it doesn't try switching to another outlet, and if that doesn't work then you may need to replace the power supply which would probably cost anywhere from 140 to 200 for one.

Screen black. Power light on unit flashes red slowly. Power light on switching adaptor power supply flashed green slowly.


Sounds like the battery might be low which would cause the red flashing light and dark screen. Let it charge for a little bit then try turning it on again. If it still does it with the power supply plugged in, make sure there isn't a lens cover on it, and switch modes or try getting into the menu to see if you can get anything to come up. If that still doesn't work then it sounds like there might be a problem with the camera.

Solution is simple....

First, unplug power cable from the back of your TV. You will notice the flashing light is still flashing. Don't worry, go to the Second step.

Second, keep pressing on the POWER button, located on the panel at the top of your TV, to shut off your TV. This will stop the flashing light from appearing.

Third, Plug the power cable back onto your TV

Fourth, press the POWER botton ONCE, using the same button used in the Second step to turn your TV back on.

Fifth, you will see the POWER light comes on, as normal.

Sixth, using your remote control, press the green button to turn on. Your TV should work as normal.
