Question about Samsung HC-P4752W 47" Rear Projection HDTV-Ready Television

1 Answer

Blue Halo Across screen

I have a Samsung rear projection tv that now has a blue tinted halo across the screen. It is more prominent in different screen lighting scenarios. One thing that I noticed (figured the more info, the better) Is that if I was watching Football, and the time, score, down and what not is posted on the top of the screen, this information was duplicated in a blue hue across the screen in an arc shaped like a happy face. The TV has been moved as of late,as I was working around it and had to move it in and out @ 4 times, but when this occurred, it was instantaneous, and after one of the moves.

Thanks So Much!

Re: Blue Halo Across screen

Hello Damianian, I too have this hdtv and had problems with the convergance and self-focus within the first year of ownership. I called Samsung within the waranty period and they sent out a tech who replaced the convergance board for free and did the manual convergance in my home. After this, with the new upgraded convergance board installed, the self-focus was not necessary anymore so I turned it off. Some time later the convergance needed done again so I called to get a price on them coming out again to do it. I didn't like the quote they gave me over the phone (around $200.00usd) so I looked for a Service Manual online and found one on an Ebay store for a total of $13.00usd including shipping. I now perform the manual convergence on this set myself and it's easy to do.
Anyone wanting to get a Service Manual for their hdtv or other technical device should check these guy's out. They now have their own website.
I hope this helps, good luck!

Hi , it seems you are experimenting a light engine problem.Here's how your tv works: Basically there's 3 LCD chips that create the colors and image by blending together.When these chips start to melt you will get those blue spots, pixilation even vertical lines.You will need to replace the light engine. Have a blessed one!

Green "halo" around the bright white images

I have a Samsung HCM5535W rear projection TV that had pretty much the exact same problem-- a green halo around bright white images. I researched it on the net, and determined the most likely problem was with the convergence STK-ICs, or the convergence board. I bought a replacement board with the STK ICs and installed it, but no luck, the problem persisted. I decided to mess with the manual focus adjustment on the green crt (i was seeing a green halo), and that fixed it. As it turns out, no replacement parts were necessary to fix the problem in the first place. Hope this helps somebody out there.
