A 6 flash shutdown can indicate power supply problems or an open thermal fuse. To be sure, you should have a technician verify your problem.

My 12 year old Sony KP-53V80 TV suddenly turned off and will not show a picture just a small rainbow at the top of the screen, then a whistling sound, crack and turns back off. can you help?


sounds like the inverter went bad...There's a high voltage device in there that runs the whole "picture" thing. There are capacitors involved with it that have probably failed leading to this mess.. That would be what that "crack" is...If you try to turn it back on does it just "click " and then stay off?

The standby/timer is flashing 6 times on my Sony KP-53HS30 TV


no the 6 blinks indicates a missing voltage. If your talking about a sony lcd KD or KE model you probably have a bad thermal fuse. You must also clean or change the Lamp fan so it won't blow again.

Sony KP-53xbr45 problem


on your model which is a RA-1 chassis the power light blinking steady just means the standby voltages are operating, so you will need to trouble shoot the power supply. you will either need the service manual or training manual to trck down the faulty component.

30 seconds then goes to the self-diagnosis function. Something is wrong with

board, also check Q218, 219, 220 on the A board. Also unit be in IK blanking,
try turning up screen slightly.
