SOURCE: Sony KDF-E55A20 55 in. LCD... Problem red light flashes 5 times

A 5 blink error indicates a bad lamp driver. However a lamp may possibly cause this too. I suggest putting a new lamp in if you have one just to verify the lamp is not the problem. If it still fails with a new lamp then the lamp driver is the problem. This part should be replaced by a Sony authorized servicer. The lamp can be replaced easily by you. The lamp replacement instructions are in the TV's owners manual. Good Luck

The red light should be blinking a code. For example it will blink 4 times pause then 4 times pause or 5times pause 5 times pause, whatever the error might be. Let me know what it is and then we can help more.

SOURCE: Sony Vega KDF-E5OA10,picture will not come on, tv goes off.

There is a real good chance that the lamp fan is not turning. If you look with a flashlight in the vent on the left side looking at the rear of the set and have someone turn on the unit, see if it spins. if it doesnt, the protect circuit in the tv will not let the set turn on. Replacing the fan will cure the proplem if it is not turning.
Hope this helps,

TV quits working, screen goes black and red light next to power green light flashes 4 quick flashes . After a second or two of no flashing,red light repeats "code" flash. We pull the power plug at the TV,...


The Sony diagnostic routine for 4 blinks indicates it to be a vertical deflection problem.

Did you see a solid horizontal line in the center of the screen prior to it going out? If so, that is a tell tale sign for vertical problems.

basic sony reset below

The STANDBY light will flash if the television detects an issue within the television. Some of these issues can be resolved simply by following the steps below to reset the television.

  1. Turn off the television. IMPORTANT: For a projection television that uses an internal lamp, wait 5 minutes after turning off the television to allow the lamp to cool before continuing with the following steps.
  2. Unplug the television power cord from the electrical outlet.
  3. Let the television remain without power for 60 seconds.
  4. Plug the power cord back into the electrical outlet. NOTE: If the television is plugged into a power strip or surge protector, remove it from the power strip or surge protector and plug it directly into the wall outlet. If the issue is resolved, the problem is with the power strip or surge protector and not the television.
  5. Turn on the television.

If the issue is still unresolved after following all of the troubleshooting steps, service may be required. Please note the number of times the STANDBY light flashes and relay that information to the service center

Sony bravia kdl55hx729 3d led tv turns on 3 seconds shows picture than four red flashes


Hello,
the error light sequence that you are seeing is indicating a "backlight error". Most likely you have a bad inverter board -the board that powers up the back-lights behind the display panel. They might be available via ebay if you are a DIYer, or you need to call for sony service.
Good Luck!

Red flashing light


  1. Five blinks - AKB circuit (automatic kine bias), the timer/standby indicator blinks for about 30 seconds then goes to the self-diagnosis function. Something is wrong with the video. Check video out, Q705, 732, 761 and other components on the C board, also check Q218, 219, 220 on the A board. In addition, unit could be in IK blanking, try turning up screen slightly.

Sony TV model KDL-46Z4100, standby light flashes 14 times, no picture, no sound


14 blinks to Sony Brand LCDs indicates a 'Backend error'. It means that, the main board to this TV should be checked for fault. In most cases the main board might need replacement, and a software update too. If you wish to know more details about this blinking code, check this link. It has details of blinking codes to several brands of TVs including Sony. Actually the work is a skilled one, need experience.

Standby Red Light Flashing


six flashes corresponds to "Horizontal deflection stop". In turn the "supposed malfunction" is then either Q5013 (H OUT) is broken and/or IC507 (H Jungle) is broken.
however i would check
Video out, IC7101, 7201, 7301 and others in C board circuit.
Q510, 516, 524 (A board).

There are actually three C boards, the CR, CG and CB boards. They are attached to the rear of the red, green and blue CRTs, respectively. I wouldnt attempt to repair the set myself. I would solicite the services of an authorized Sony servicenter.
