Question about Samsung HCN5527W 55" Rear Projection Television

1 Answer

Bad picture About nine months ago, the picture on my TV had blue outlines around people (it looked sort of like a shadow). Now, when you look at the TV it is like you are seeing it in double vision, there is a blue line across the screen and all the colors along the top of the screen are red. The model that I have is an HCN5527W. I had a technician look at the TV and he suggested that I have a couple of parts replaced. One of these parts had model #'s STK392 040 and the other parts were on the mother board and were black and cylindrical shaped, but, I could not see a part number.

I have a pioneer tv model pro-720hd. The picture just went fuzzy and everything has a blue shadow around it. What could be wrong?

Sounds like a problem in the blue HV convergence circuit, bad yoke or IC chip that drives the yoke coils.Could also be a bad blue CRT. Look at IC901, STK392-110 and releated components in the circuit, page 97 of service manual.

Blue shadows on my philips projection tv

You have possibly contaminated fluid in your blue picture tube if it has a hazy look.Blacks and whites look bluish and whites have a blue bloom to them.The other problem could be bad convergence amps.This would be double image around letters on the screen.
