Question about Sony KP-51HW40 51" Rear Projection Television

1 Answer

Sony KP-51HW40 51 in. Rear Projection turns blue

My television turns on fine but within just a few seconds/minutes the screen fades into a full blue screen. The only way to get the picture back is to turn off the tv and then again I only get a few minutes at best. I have already reset the tv, turned it off and let it sit for five minutes, moved all other electronics away from the tv and still it fades to this blue screen. Please let me know if anyone can help. Thank you.

First reduse the G2 voltage for the blue c.r.t,and watch if the unit works for longer period (offcource blue colour will be not present).After reducing G2 voltage to blue c.r.t still behaves the same than c.r.t is faulty and you have to replace.
Pls count the red led blinking when it goes off,incase it goes to std by mode.

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,

Picture comes on then fades to blue

Check the info from this website to see if you are able to fix your TV. You should turn the blue screen control down slightly counterclockwise. If that did not work, then more likely you have a video amplifier IC defective or a blue CRT.

The fix for this is here somewhere, as I had the same problem last January and the solution was posted here in March last year. I'll try to find it and post the link to it for you, later.

Blue screen

This is easy to fix, pull off the front grill and turn the bottom left trim pot anti clockwise until the picture comes back. I am asuming the picture there and then it fades to blue. There is a step by step instruction on how to get the whole thing apart
