Question about Samsung HCN553W 55" Rear Projection Television

I did try messing around with the color settings, the coverting settings, they all do affect the tv but does not seem to make the ziggy zaggy lines get worse or better. Is there anything else that I could do at home before I call in someone that charges me a lot of money just to look at the TV. One other thing is that it seems to have a lot of yellow color around the boarder of the tv. Please help!

You will need to replace or have replaced the two convergence amp IC's on the convergence board in this set. They are the STK-392-040 IC's and the original replacement numbers are available at MCM electronics. Go here to see. Or you can call PTS corp, as they have rebuilt complete convergence boards or can rebuild yours for you at 1-800-844-7871 Good Luck

Colors on the screen are messed up with ghost HITACHI

Its not clear what kind of tv you have but it appears to be older rear projection tv with three picture tube. This problem does occur due to the convergence board going bad. Needs professional help to repair unless you know a lot about soldering ICs. Check out at for more answers on this problem, repairs and costs.

When moving the 51pw9363 will the color be affected by weather and movement, TV's color was good and then moved to the basement now the color is all messed up tried the convergence seem to have no effect

Usually temperature will not have a big affect but high humidity will. I would suspect the convergence amps have possibly developed loose solder joints from the move. They are mounted on heavy duty heat sinks that can move a lot and crack joints. Hard to say. Thanks for using fixya.

see if there is a "default" option, if not set everything back to the middle, if the colors are still off you sure its not the convergence?
most big screens allow you to change "color temperature" it's like a default adjustment for 3 different brightness levels.... ie...COOL, WARM picture will show obvious changes in brightness

Samsung HC-P4752W No Color

Do not automatically think you need to go into the service menu. I bet you 100 to 1 that you pulled out a plug or a connector somewhere OR one is not seated into the plug all the way. If the set worked with color before you messed with it, there is not a problem in the service menu. The service menu is not the fix all thing. it is there to make fine alignments and adjustments, and as a matter of fact, messing with a service menu even with the service manual is very dangerous. I have seen peeps ruin TV sets by messing around with the service menu alignments. STAY out of these alignments. they are not going to fix a problem that all of a suddenly comes up. Repair the problem in the circuit first. Good Luck
