Sony BRAVIA Fails to fully Power ON. TV shuts off when backlight should kick in, after logo lights and fades. 'standby' blinks 6 times.


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.

TV goes to blank screen standby after one second of normal functioning green power light on. When in standby state, the TV is blank like it's off and the red standby light blinks FOUR times.

Model WS55819: Shut off by itself. Power ON with remote, Green light next to power button on TV flashes twice fir 10 cycles and shuts off. Unplugged TV for 30 minutes and for 4+ hours. Same results.


The Error Code designations indicating a malfunction, or no malfunction, are listed below:

"12" ... indicates no error has occurred.

"21" ... X-Ray Protect circuit.

"22" ... Short Protect circuit.

"23" ... Horizontal Deflection failure.
"24" ... Vertical Deflection failure.

you will have to count the blinks, then there is a short pause and then following a second set of blinks this tells what is wrong with set.

Sony KDF-50E2000 shuts down and blinks repeatedly twice.


The 2 blink error is a temperature error and the 6 blink error is a thermal fuse error. You may need to unplug the set and get you a can of canned air, take off the back lower cover and blow out all of the fans inside the set.

If blinks continue without any pause, the main board is faulty.

Tv keeps turning off?


cutta, you will most often hear a click on boot then the fans start up and lamp will then fire. The picture will start to show up....at what point does it shut off? and do you hear a click when the tv is turning off? Is it the complete tv shutting down, fans and everything that turns off? Do you see any lights on the the front panel "POWER", "STATUS" or "LAMP", what are they doing? If you see a Power, Status or Lamp light after it shuts off the below are what they mean if there is an issue. POWER - STATUS - LAMP - CONDITION/ISSUE: Off - Yellow - Off - Temp. high/dirty filter/excess room temp Off - Off - Yellow - 4000 hrs. Lamp usage warning Off - Off - Blink Yellow - Lamp Cover open Off - Blink Yellow - Off - Air Filter Cover open Off - Off - Red - Lamp failure (failed to turn On or broken) Off - Blink Red - Off - Fan Has Stopped Off - Red - Off - Circuit failure (short) or DVI cable disconnected If you want to check for the last "Error Code", after you first turn the TV on, by pressing the front panel ?DEVICE? and ?MENU? buttons at the same time and holding them for 5 seconds, it activates the Error Code Mode. The ?Power LED Light? blinks/flashes (1/2 sec delay) and then flashes again denoting a two digit Error Code indicating no problem or an error has occured since the last Initalization. i.e. "Power light" blinks 3 times (1/2 second delay) and then blinks 4 times then 1 sec delay and repeats a few times. This would mean "Error 34 - Lamp abnormality". See below for error codes..... Error Code - Description or issue 12 - No Error detected, check Power Supply 32 - Lamp Cover is open 33 - Air Filter Cover is open 34 - Lamp abnormality 36 - Light Engine (DMD or LAMP Fan stopped) 37 - Exhaust or Lamp Ballast Fan stopped 38 - Lamp temperature high 39 - DMD temperature high 41 - Short is detected 44 - DVI cable between FMT & Engine disconnected. Sorry for the long answer but it was an open ended question.
