Question about Sony Televison & Video

1 Answer

How do you fix a sony kdl 52xbr9 that has a black screen but the green led is on?

I've replaced the power board and the problem remains. I've taken the back off, turned the tv on and noticed that when the room lights are out that I don't see any backlight. I'm thinking backlight inverter board what do you think?

Why does it have six red blinking lights?

Hi Tim
In my opinion
No... the LED's are doing their job
Error reporting
Modern TV's are computers and try to indicate where a problem exists.
Does it need a Firmware upgrade?

Red green or orange lights are on or blinking on the TV

My TV does not power up,Sony KDL-52XBR9,it tries to trigger the relay on power supply board G7N 4 times(RY6101) then it turn to blinking red LED 10 times per cycle.Is it power supply fail?which part?

Sounds like main board fault. These blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices.
Blinking codes details to many popular brand TVs are given. Surf the site with patience.

Sony KDL-52XBR9 power/standby LED blinking. TV turns on for a few second and then turns off.

This is either your LCD backlight, inverter/power board or both. Neither of which are serviceable by the consumer, unless a visual inspection of the power board shows swollen or ruptured capacitors. This you can do yourself and is the most likely problem. Just read the side of the capacitor and go to radio shack, or online to find the right replacement capacitor. When re soldering be sure your negative and positive leads are in the correct holes.
