    The indicator lite blinks 8 times

  • Anonymous Dec 29, 2007

    When I turn on the tv the screen is blue with a few wavy lines there is a buzzing noise. Then the tv shuts off after about 30sec. The LED on the front at first blinked 8 times now it is blinking 5 times. I looked inside the tv and noticed the buzzing sound was coming from the bottom of the blue crt (lamp). It is sparking at the bottom. I looked into a replacment but the part is dicontinued. Needless to say Im not very happy. The part number is (8-733-656-25). I just bought a Grand WEGA KDS-55A2020 55" rear projection (sony) $1789.00 Awsome T.V.

The problem sounds to be in the power supply board. May also be a horizontal drive problem. Sorry I can't be of more help, but there are may voltage problems ( shorts, open capacitors, bad chip etc ) that couls cause this problem. The reason the set turns blue when it first comes on is that it doesn't have time ( or can't find a signal and the screen default to blue. Wished I could help more.

My Sony KP-46WT500 screen shows the tv image in blue only for a few seconds, then it goes completely blank (as if it were off). Do I need to replace the bulbs?

It is rear projection TV that use 3 picture tubes of red-green-blue to show color picture on tv front screen.
Do you see standby red light blinking when TV shuts off after showing blue image for a while?
If red standby light is blinking, please count it how many times it blinks, there would be 3 seconds pause between blinks so count pause to pause and post it here to find out possible solution.

Turn on the big screen sony tv, but fades to blue

You probably have a bad BLUE CRT. Due to the cost and the length of time it would take to repair, I would not invest the money into it. It would require a Qualified Service Person to come to your home and remove the BLUE CRT assembly and send it back to SONY to be rebuilt. Estimated cost would be around 800.00. I would check prices of a replacement set.
I hope this helps,
