    Same issue, but with Red. I am just going to toss as it appears to be an issue that takes hundreds of dollars to fix unless you know what you are doing.

I had the same problem and paid $300.00 cdn to fix...1 or 2 of your clolr cards are done...they usually last 3-5 years. Its worth the fix. Try adjusting the colors through the convergence setting.

Yes i have a tantus samsung 40" tv and my problem is that the colours are out of alignment red green and blue so your almost watchonf 3d almost can this be rectified can it be fixed


If this is a tube set--and it sounds like it it--it likely needs convergence chips. IF the color and picture was ok before this happened--it is worth a look, but if it was getting dull and fuzzy, BEFORE the convergence problem--it needs tubes and is NOT worth repair.

Hello tv has warped bottom and top screen on a rear projector samsung and blurred vision with red,green blue colurs not aligned tried to tune to no avail Samsung rear projector tantus sp42w4/42w5


The colors tell me of a convergence IC issue, warped bottom and top tell of another.

see this page on reparing the convergence problem yourself
http://cmpalmer.blogspot.com/2006/11/fixing-my-own-tv-part-ii.html

also compair the before and after pictures to see if this is the other problem your having.

Then you have another fault, which im not completely sure of right now. I will look into it.

Samsung rear projection tv smells


I would first suspect bad connections and/or a defective convergence IC. The burning is the current limiting resistors getting hot. I would stop using the set and get it repaired. Replacing the convergence ICs should have a pars cost in the $40-$60 range. The few resistors that should also be changed should only add a few $$ to the cost. Add in the local labor rate for the total repair cost. Also, request that the ICs be changed rather than the whole convergence board. It will be less expensive and won't require a complete convergence adjustment. Dan

2003 Samsung HDTV 1080i 42" wide screen has just developed picture problems distorted and red. Almost looks 3D. MODEL NO.:HCN4226WX/XAC SERIAL NO.: 37083CEX400297E


This is a convergence problem and can easily be fixed either by resoldering the pins on the convergence ICs or by replaceing them if they prove to be defective. Can you solder? Do you feel confident in replacing these parts?
Keep us posted.
