2 red LED flash (power fault) on Sony Brava KDL 40v2000


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.

If blinks continue without any pause, the main board is faulty.
Search the site by type in the "brand name" to your device, in the "Search box at the top right of the display window of the Homepage" to get gathered related posts.

My tv flashed on and off and left with 6 blinking lights. Did a power reset and tv powers up with Sony on the screen then goes dark but the green light stays on. Screen is dark. Which panel is bad.


Probably the back light inverter is faulty . Before going to buy a new inverter board tey to check the power supply. Which the bellow added video to know how to check a power supply board. You have to check the 24V power sto the inverter board from the power supply. if its not there then the problem is with power board. If its ok then you have to go for a new inverter board. Also try to replace the electrolytic capacitors in the power supply board. some times bad electrolytic capacitors can lead to back light failure.

The screen will get extremely dark (sometimes a dark red or green) and will flicker on occasion as if it's trying to fix itself.


Back - light problem. Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis.
http://electronicshelponline.blogspot.com/
In some models of LCD TVS; the backlight inverter and its T'Con board will be a part of the panel itself, and will be a built-in type inside the LCD panel. If so, they can't be replaced. In this case; a panel replacement is the only repair. For some other models, the backlight inverter section circuit will be a part of the main power supply regulator [SMPS]. To such sets, the power supply section circuit too should trouble shoot. Contact any service technician. The circuit will differ with models and versions.

Why does my Sony KDF E55A20 LCD projection television stopped. It flashes green 3 times at power up and then continuously flashes red in 6 flash intervals


The problem is sort of complex. This could be the main power supply, or the high voltage supply. There is also a chance there is a short on one of the boards and the main supply is tripping to protection.

This is not something you can fix at home. In consideration of the service cost, and most likely the circuit boards and many of the parts will no longer be available, you should consider a new set!

Screen goes blank aftert 10 mins sound stays on though, wont come on again till been switched off for ages, and then picture still only 10 mins then sounds stays on again


when the TV goes dark, shine a flash light on the screen- hold it very close.
if you see a little bit of the image, your backlight has failed. That would mean you would need to replace the LCD panel.

KDL-40XBR4 bought 1/08. Turns on for 30 seconds with screen staying dark. Then it goes off automatically with the stand-by light blinking 5 times repeatedly. Took it to the shop and he said the LCD panel...


KDL- Bravia blink codes (Australian):
2 times-Main power supply voltage error (12V, etc)
3 times-Malfunction of 3.3V line
4 times-Malfunction of 5V line
(Voltage Supply to FE, etc)
5 times-Malfunction of power supply for screen
6 times-Malfunction of inverter or overcurrent, etc
7 times-Abnormal temperature inside unit
8 times-Audio circuit error (amplifier, etc.)
9 times-Fan malfunction
10 times- Digital FE circuit error
11 times-Malfunction of Trident IC or around IC
12 times-BH board error
13 times -Malfunction of balancer
If this is correct the 5 blinks is the power supply having problems, I would much rather change the PS than replace the screen. Also if screen is determine bad, look for class action lawsuit on Sony for defective screen, i am told they know all about this.
