I need the outer screen for my Samsung HC-P4752W. Mine has a red line that seems burnt into it. Where can I get one?


It sounds like the RED CRT is cracked which will cause a red line. You can verify by looking into the lens of the Red CRT with a flasnlight if you see a line the CRT needs replacement. If no line then chances are the Convergence IC may have a problem.

RED CONVERGENCE SCREEN PATTERN BOWING AND CAN'T ADJUST


The most likely cause is shorted convergence chips and possibly a few pico fuses.

These sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the picture to look normal. This is called convergence.

When its out of alignment the video will look 3-D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired. Convergence problems are very common on all Projection TV sets including Sony,Samsung,JVC,Philip Magnavox,Panasonic,Akai,Pioneer Hitachi,Mitsubishi,Zenith and others.
You can get a convergenece repair kit with instructions from the links below.

Here are some of the most common problems with these sets...

Problem #1) Convergence

Yours may have one or more of the following symptoms...

*Screen Looks 3-D
*Colors wont align
*Screen may look distorted or warped
*No Audio/Video - TV Shuts down - May also make a constant chirping sound

Problem #2
Another common problem is dull or washed out video.

Your set may have one or more of the following symptoms....

*Dull looking picture
*White looking picture
*Halos around objects
*Red/Orange looking picture

Not sure of the part number most use STK392-110 or 120s . You will need to look at the ics in your set they will have the IC numbers stamped on them they will have STKxxx-xxx whatever that number is thats the sanyo part number for those ICs

the convergance amps have failed you need to have them replaced there are 2 of them and some resistors may be affected. the cost of this repair can reach $350.00 depending on the tech you get. this is the most common failure in rear projection TVs. the convergance amps work very hard and are bound to fail. they also have very large heat sinks to keep them cool. heat is the biggest enemy of transistorized ICs.

Samsung HC-P4752W Blurry ONLY on HD Channels


Similar problem, then about 2 weeks later the SD convergence went out. Changes convergence Amps,,, Now I'm trying to learn what 2 red flashes mean now when I try to power it up,,, it flashes twice then shut down into standby mode,,, I got no picture after installing STK392-040 chips, thinking about trying another set as atleast I had blury picture before. No solder shorts of opens that I can find. TV has always been a pain,,, locking up once in a while such that you can't change modes,,,
