6 Answers

Strange colors and shadowing and then went black.

I have a 6-year old Sony KP 46WT510 projection tv. This morning upon turning it on the picture was very strange colors and shadows, then after about and hour the screen went black. The standby light is flashing 6 times. What is the cause and what part would you suggest replacing?

    I noticed that upon immediately turning the tv on now it blinks 4 times at the same time it is powering down and then blinks 6 times repeatedly until I turn the tv off. Don't know if that changes your diagnosis. Any way we can fix it ourselves or is a repairman the only solution.

    Since I am not an expert in tv repair I think the solution of replacing the whole mainboard instead of pieces of it was a good idea. Thanks.

I would replace the main board as it would be cheaper to replace the whole board than to go piece by piece. the whole board should barely run 100.00 maybe 150.00 and would solve the problem

6 times blink shows problem of Low B Over Current and/or over volt protection.
Problem can be few parts in A and B boards.

I need bit more detail of strange shadows in picture.

    4 time blink and then 6 times blink.

    4 time blink shows problem in vertical deflection area of TV.

    6 times blink has been already described.

    If you are familiar with TV repair and have necessary experience, basic electronics knowledge and tools then its good to do it yourself. OR local TV repair shop is better choice to avoid further damage in TV.
    Good Luck.

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.
HQ
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.
