Samsung HCN4226W picture is concave	Can't Post

Is there a quick fix to this. the picture dips in towards the center on all sides. What is the cause of this and is there a quick way for me to fix it. everthing else seems fine about it

?Replace the TV with another set? Smile

Otherwise try posting a pix (or link to a pix).

I think we both have the same problem; I posted a question but I'm still waiting for help; I'm not a TV tech but I have been reading in other forums about problems like this in these units. Take a look at this board with the Big IC's (STK392-040). When those IC's burn out you have problems similar with what you are describing. Do some reading on the CONVERGENCE BOARD it might help you.

If you look at the pictures posted by KLong on this post http://www.tv-forums.com/...ence_problem_P44442/
that is what my tv is doing. Appears to be a settings issue to me. If it is a settings issue like mute 1+8+2 or mute 1+8+3, anybody with the instructions for mute 1+8+3 on how to set it and what each button on the remote does would be greatly appreciated

Entering or making changes in service mode by untrained persons can cause significant and permanent damage to your television. If you are not qualified to service your television, please DO NOT ENTER these service menu codes.

(remember the guy in that thread regretted NOT writing down original settings).

SERVICE &/or Training manual time (possibly with the educating to go with them). Unimpressed
