I have a Samsung Rear Projection TV with an HDTV 1080i Monitor. I know the convergence is messed up because the blue would not move when I tried to adjust it on the menu. So, then I tried to make it


You will need to replace both convergence Ics and the pico fuses that blow when the Ics fail. You can get the replacement Ics and pico fuses from www.tvreairworld.com they also provide free tech support to help you install them

Hour glass bowing on the top and bottom of my HCP4752W Samsung


Check the resistors near the ic, and the fuses to the ic's, i bet you will find an open fuse. the fuse will look similar to a resistor without color bands. use a dvm and set it on ohms, with the tv turned off.

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

You can see some more examples and find a fix herebb0cf99.pnghttp://www.fixya.com/support/r2861467-solution_video_looking_whiteish_dull

I would quess that its most likely a resistor that opened when the origional IC went out. I dont have the specifics on your set. But rule of thumb is to run the set for a minute then shut it off and the affected IC will be much hotter than the one thats not having difficulty. I will try and locate a service manual for your model and look it up for you. I will repost if I find out which IC controls RED.

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

Samsung HC-P4752W Ghosting, seeing yellow, bowed lower left


What might be happening is that your convergence is out of adjustment. Before removing the Convergence ICs try to adjust your convergence either from the onscreen adjustment (see your owners manual) or by using a signal generator (if you have one). I am against this "lets start swapping parts out" craze that has become the norm because you never fix the cause of your problem just the symptoms. I would suggest trying to adjust the convergence first. Thank you, Shuttle83,

HC-P4752W Blue Convergence??


You can replace the whole board, or opt to replace just the 2 IC's and a resistor or 2 that has probably failed. Lift the chassis & inspect the pins of the 2 IC convergence chips for hair line cracks around them. Inspect the small resistors out in front of the IC's for discoloring or burnt look compared to other similar resistors. The convergence board will cost much more than having the above repaced. Chips about fifeteen a piece, resisters .50 cents each plus shipping. Convergence board $100 plus.
