Having trouble with samsung projection tv / sp43w6hpx/xeu. done manual convergence and got the picture and colour nearly right but across the top half the tv the picture is bend upward/ what kinda part...


Look for 2 big black ICs they will have the Part number on them,example STK392-110
Mats Electronics has them replace Both ICs. 1-800-628-1118 also in front of ICs is 2 resistors low ohm 2.7 or 3.9 replace them.

Have 47" Samsung HCL743W rear


Here is what to do to confirm what problem is, go to black and white program and make sure color adjustment is turned all the way down to zero.

What you are looking for is what color is the screen?


If it a primary a yellow looking screen (all or most) you have bad Glycol in most likely the blue tube. These sets have a sealed area with a sealed area with Glycol (it is like antifreeze and meant to keep the face of the the three picture tubes cool).

What can happen (usually the blue) is it becomes contaminated with bacteria====note, if blue tube is contaminated you will have yellow screen (red and green=yellow.0

The real easy way to confirm if this is the case is with the back removed and access to the three large lens on top of the tubes look into each lens, if the blue one has no picture and looks like a floodlight, but the red and green have a picture, YOU HAVE FOUND OUT YOUR PROBLEM.

I can tell you if this is the case I can tell you what is involved, this most likely is not a do it yourself repair but i can tell you what is needed.

this issue is caused by a failure in the convergence ic's and possibly a bad resistor and fuse in the circuit if you need instrution on how to change I may be able to help though it is kinda tech heavy

I own a samsung ln46a530 and need to configure it for the best picture.....any recomendatios?


If you haven't already bought a nice set of HDMI cables, go ahead and do so (just dont fall for the "gold plated" cables as they are a gimmick). Unfortunately, while we all want that HD quality, there seems to be some problems with the ln46a530 when switching from RCA to HDMI. On the bright side, they have been resolved in this forum post.

SRS TruSurround XT: On

Blue flashes on screen and then just quits


post your model. Sounds like the blue CRT is shorted. But let me know the model and I will let you know how to test it.

Distorted Color and geometry of Picture


I've posted this solution several times but here goes. Try setting up the convergence through the menu by accessing the convergence setup menu. If this fails to work you have a bad digital convergence box and need a tech to replace it. About $60 to $100 fix.
