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...

...OK to begin troubleshooting this. Unplug the set and leave for 1 min then plug up and leave for 2 min push the power button and let light blink for 2 min.... now push and hold at the same time the MENU and DEVICE buton st the same time. this is the self diagnoses feature ... the lights should link then pause then blink again... this 2 digit code will help narrow it down. Also have you check the lamp yet?

BLINKING STANDBY LIGHT AND NO POWER


there is a possibility that the power switch capacitor has bubbled or leaked a remedy is to unplug the unit from the outlet for at least an hour then try to power it back on.

i will try to look for more information about other work-around's or which of the other parts are defective or almost defective, that is causing the problem.

Sony Triniton Wega Model KV 32HS510. After pushing the power button,the tv starts to power up, then the standby light blinks 7 times then pauses before blinking 7 times again. It continues to do this,...


This is usually an indication of a failure in the scan amplifier sections. When the scan amplifiers or high voltage sections fail, the main power supply will usually also require servicing.

It is very common that the fly-back and high voltage multiplier and also the horizontal output stage fails in these sets. Along with it, the power supply will usually require to be serviced. On rare occasions, the vertical deflection amp fails.

Kds55a2000 red light flashing


The SONY Owner's Manual for the KDS55A2000 does not state what the 4 times blinking Power LED means.

However, my Sony Extended Care Service support insists that the projection lamp is the cause for the 4X blinking LED
Power light.
I do not agree but am forced to buy a replacement lamp (not cheap) to prove that the problem is probably the fan, as the TV Technician states elsewhere in these FixYa support questions and answer
