Samsung HP-S4253 Plasma TV Problems

[Mathus]

Ive been having serious problems with my Samsung plasma 6th months after buying it. Its been a year now and ive exhausted what i think it could be. As you can see from my screens a blue line appears on the left side of the tv distorting the pixels. It seems to only appear after watching for a half hour to an hour and isn't constant. It fluctuates in a wavy manner sometimes being very small and sometimes very large.

I have a 4 year Best Buy warranty that can handle any repairs but i have not called it in because i feel like if i give it to them they will tell me there is no problem because the problem doesnt appear instantly.

I dont know many technical things about hdtvs but at one point i thought it could possibly be interference from something and at others i thought it could be temperature, but after turning everything off in my room and just the tv on it didnt go away. Also, after reviewing my manual i can see that i am well within temperature range.

My tv,xbox,direct tv reciever, and old sony dvd/surround reciever are all plugged into a flatscreen monster home theater powercenter.

I would really appreciate help with this. If you guys can provide it then i will be very grateful.
