Set was on and made a loud pop noise and the picture went off. the red light was flashing and no picture. then it made a strange buzzing type of sound a few times. turned off for a couple mins and then...


It sounds like your screen inverter has just gone >bang< unfortunately.
Most screens inside use 2 main circuit boards, and you are most likely going to have to change one of them.
It's possible also for it to have been just the backlight bulb making the loud pop noise too. The inverter may have given out too much power and blown the bulb (a lot like you hear when a house bulb goes bang).

If you can't actually hear any TV sounds (normal sounds like music, voices etc. when they should be there), then it means the problem is more serious, and would need a specialist repair place to check out the electrical circuit inside.

Sony kp-51ws500...i turn it on and get a blue screen..can hear audio..but the standby/power light flashes then turns off.. count 8 flashes please help..thanks


Sounds like from your description the Blue CRT ( picture tube ) is shorted. I believe they are no linger available. If in doubt, I would call a service company to verify this.

Tv turns on w/pic then pic dissapears light blinks 4 times


I have the same issue, we've had to change our bulb three times in less than two years. now we have 61" expensive paper weight. Our current bulb is less than 6 months old. The TV is only 2 years old and like i said this is our third bulb.

the blue light blinks 4 times. you get sound. then a few minutes the the picture returns... then it goes out, and the cycle goes on.

A solution to this would be greatly appreciated.

Blue flickering light, no audio


You will need the service manual in order to get that chassis out. once out it is an easy repair to replace the capacitors yourself. I just did one the other day. You will need the service manual for sure it will save you alot of money on repairs. heres a link where you can get the factory service manual.
