it sounds like your back light might be going out. You might be able to fix this by installing a new backlight inverter board.

Most likely this is caused by a defective main board. Changing the main board will fix the issue about 95% of the time.

To be absolutely sure, the voltages need to be checked on the power supply. If they are not the values listed in the service manual, then you should replace the power supply instead (accounts for the other 5% of the time).

Sony kdl-52s 4100 power supply ok but no sound and display


Well, if the power supply is in good working order, you will need to verify that the proper voltages are getting to the main board. If the main board is getting the proper voltages, I would bet you have a defective main board. The video and audio signals are generated on the main board. Expect to pay $100-$150 for a replacement main board.

Blinking red light. power off power on no success


May I suggest, you have a bad power supply. I did repair this model once, in that case it was a bad signal board. I would certainly think that the power supply is at fault in this case. This would be more common than a signal board. I wish I could provide with a complete repair. I would investigate with my first option. Thanks for asking and show all hands of support!

I have a Sony KDL52S4100 LCD television. The power light is on but no picture is displayed and not powering on


When you say the power light is on but it is not powering up, what do you mean by that (just that there is no picture)?

Sounds like the inverter has died or the backlight bulb. Either way, it needs a techy to fix.

Its fixable problem like power supply board replacement will solve the problem.
Unplug tv from wall socket for couple of minutes, replug back in and turn it On.
If problem still exist then most likely power supply got fired and will be replaced, local tv repair shop will help you to replace power supply board.
Thanks.
