The light is blinking a code to alert a tech as to the cause of the fault protection being activated, I recently repaired a panasonic, after tracking down a service manual to get the code definitions I found them printed on one of the circuit boards when I got the back cover off. Seems the most common cause is the convergence ICs, in this instance there is likely a short in one of the chips that is throwing voltages off so much that it won't let it power up at all, to prevent further damage. I have the same set and need a schematic, that's how I got here...

The power light blinks 7 times, pauses, then blinks 3 times. have sound but no picture.


Please disconnect the set from AC power for 2 minutes, then upon plugging back in, press and hold the power button for 8 seconds to try and force a reset.
If the TV still does not power up, then the 7 blink code would indicate that there is a short inside the set stopping it from fully powering up.
It is most probable that there is a failure on the power supply board inside the TV. Commonly the capacitors on this board will receive a surge and then fail. They can sometimes be visually verified by removing the rear of the set and inspecting them for bulges or leaking fluid at the top or the base of the caps. This is the most common mode of failure for these sets.
The capacitors are located on the power board inside the set, where the AC cord plugs into and can be replaced by a Tech for no more than $200 parts and labor.
Unfortunately there is no sequence of buttons or reset you can perform to get the set working again. Do you have any experience testing live voltages, or soldering on electronic equipment? If not, take it to an electronic repair shop.

Re: tv kdl-55ex620 red light blink 8 times Do a Power Reset. 1. While the TV is off, unplug the power cord of the TV from the electrical outlet. 2. Let the TV remain without power for 60 seconds. 3. Plug the power cord back into the electrical outlet. (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.) 4. Turn on the TV. 5. When the TV powers on and a picture is displayed, reset the TV to factory default settings.
  • If the Reset message does not appear and the TV turns off and on, begin again from step 5.
  • If the standby light begins blinking eight times, return to step 1.
6. After the Reset message appears, allow the TV to reset. Do not press any buttons on the remote control or on the TV and do not make any other adjustments for 1 minute. 7. Unplug the power cord from the electrical outlet. 8. Allow the TV to remain without power for 10 seconds. 9. Plug the power cord back into the electrical outlet. 10. Turn on the TV.
  • The initial setup screen displays if the above procedures were performed correctly.
11. Follow the on-screen instructions to complete the initial set up. 12. Perform a system software (firmware) update.

Power surge-no picture or sound, just red blinking power light


Any malfunction associated with a blinking redlight usually indicates a circuit problem or defective component. Unfortunately, the days of taking off the back cover of your TV and replacing a defective tube or fuse are long gone. Proper servicing will require troubleshooting procedures that can only be performed by a qualified electronic repair facility or professional television repair person. Ask for an estimate and a realistic appraisal of whether the set can be adequately fixed. Depending on the age and condition of your TV it may not be cost effective to repair.
