WHY WON'T MY HITACHI PLASMA TV SHOW PICTURE OR SOUND? WHAT DOES THE BLUE LIGHT ON THE FRONT FLASHING 4 BLINKS MEAN?


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.

I have a 4 year old Sony KDF-E42A10 television - the power/standby light blinks red 5 times, pauses, blinks red 5 times again, etc. I have replaced the lamp previously when the light was blinking red 3...


Hi there,
5 blinks means there is a problem with the video board. It could be as simple as unplugging everything, includding power. Wait 3 minutes then plug power only back in. Or it may be a damaged component that requires replacing.
Hope this helps

Typically, 4 blinks mean "Vertical Deflection Stopped." Chances are that you have a problem on the D board.

Sony Bravia KDL 46", no picture, standby light blinks 4 times


Since the TV is still receiving power, the problem is going to be with the TV's mainboard.  After you unplugged the TV and plugged it back in, you said the power light went out again, so I assume the standby light wasn't flashing again?  The flashing standby light is indicating an error code so my suggestion is to contact Sony for service options regardless if there is a warranty or not because service is the only solution to this situation.  Don't forget to provide them the error code or 4 flashes repeating.

Sony KDF-E50A10 No Picture


4 times blink error shows that any FAN is not running in TV as there are 4 fans in this TV.
Please check fan connectors and make sure all are plugged securely.

NO PICTURE


how many times does it blink? if it is blinking 4 times like I think it is... it is a problem with one of the fans (there are 4) in your TV.. It is a simple fix... try using an air canister to clean them. It will require some disassembly though.
