All tubes light up when turned on...when at full brightness, the TV shuts down indicating 8 blinks on the stand-by/timer light. Can anyone help me with this problem. Also, prior to that problem the screen had faint blue curved horiz.lines...any idea of this problem as well? Thanks in advance.

TV turns red,shuts off, stand-by light blinking 8Times

Eight blinks - Problem with the audio (AUDIO), unit goes to standby and blinks the self-diagnosis code. Check IC406 audio amp, PS401, and 402. On some projection models of Sony TV sets, this code means that T8005 (flyback transformer), or the associative components in the high voltage circuits are defective on the D board.

No picture comes up but tv powers up and the stand-by light blinks for about 3 to5 seconds, i also hear sound when i turn it on and change channels

If in shutdown the power light should continue to blink a specific number of blinks which is a error code.

This set is prone to bad picture tubes (has 3) so depending on code may be a fatal issue----sets will before flash bright red, green, or blue when this happens and shut off.

Red light flash timer stand by

Please count standby light blinks and let me know.

6 bliks on sony kp-46wt510

KP46WT510 Shutdown 6 Blinks. 6 Blinks = Low B+ OCP/OVP
SOLUTION: Replaced Flyback transformer. It had no rings on the ringer test.
Comments: Any load on the B+ line can cause 6 Blinks.
Example: If the 200v line is loaded down will cause a drop in B+ due to bright picture current demand.

5 blinks means AKB detected. Try turning down all 3 screen adjustments slightly.

Tv turns self off when turned on

Does it blink a certain amount of blinks pause a second or just blink constantly with no pauses? Let me know it will blink a code if its going into protected shutdown. And it will blink constantly for another reason.

No picture blinking stand by light

I hve worked on a number of these units , your description is typical of a shorted blue picture tube. The protection circuits in the tv detect that there is a problem thus shutting the unit down to prevent further damage. Sony had a bad run of picture tubes in this series. The replacement cost of the tube is about $250 plus labor. My estimate would be for the repair about $400-500 depending on where you live and how honest your local technican is. I will caution you however, that you could replace this tube and the red or green could go. These would not be covered by the technicians warranty. When these sets are working, they have a superb picture and it is easy to get lured into fixing them. Scrivitron
