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

1 Answer

Picture and screen

My tv has a light blue fade over the whole screen. You can faintly see images in the back but after a few seconds (about 10) the picture shuts off then the tv turns off. You can also still hear the channel.

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.

Blue screen after awhile

This is one of a group that had bad picture tubes(red,green,blue). They are no longer available unless they are removed and rebuilt and that is very expensive.

There is one other thing you may be able to do to get the set to function again without replacing the blue picture tube---Reply here to me if you want this information and I will post it here.

The other stuff is probably the Engine as well. Before going any further, have them replace it again and see if the other problems show up. I am willing to bet they wont. These Engines are mostly refurbished units and if they originally had intermittent problems on the Digital Board that comes mounted on the Engine it would get passed on to you.
I would not wait before having it replaced and I would Call LG first to let them know you got a dud replacement Engine. Let me know how it comes out.

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.

Cloudy Blue Color Covering Whole Screen

I think its time for sony to face a claas action, they do not supply parts in less than 7 years, and the unit should not have been sold so $high, they should buy them back, that is the best solution
