I just bought Norcent pt4233 second hand. Basically, after watching it for about 2 hours, I get 5-6 vertical red lines. They are very sporadic, and it looks like red pixels are moving around forming lines. I'm sorry for long description, but this is the only wayfor me to describe what's happening.
I usually turn it off for about 10 min and that I can watch it for another 2 hours. I can also increase the brightness and then the lines kinda disspear. Personally, I think that the TV gets too HOT. After I turn it off, I put my hand behind the TV and it's super hot!
I saw some threads on other forums, and people say that Norcent uses LG parts, and that I can order part from some resellers and fix it myself. The problem is that I dont know what to buy! I would greatly appreciate if you'd advise me what to do. Thank you.

Re: Eske told me to ask you!
Are the vertical lines across the entire Screen? If so it could be the control Board. If the lines only go part way from the top but not all the way to the bottom. Depending on where they are it could be the x boards. can you post a picture of your screen with the lines?

hi all i am having a Thin Vertical Red Line on my Acer LED moniter ... the screen is having a part fail(cable or the screen/control board it self.).
If it is not a feature built in to the watch to save power when it needs winding, I would say it has a bad gear wheel inside.
I would go here, join, and ask in the Rolex Forum,
These guys are really knowledgeable.
When you reset the big seconds hand to zero, the hour and the minute hand are not engaged in this function, so, there is no fault with the watch movement. Do as follows: 1) pull out crown and set the hour and minute hands at 6 o'clock (they must be lined perfectly in opposite directions) 2) push the crown in half way back (not completely) 3) push and hold the button at 2 o'clock (set the big seconds hand to zero) and release it when done 4) when big seconds hand is zeroed push the crown back in 5) pull the crown out again and set desired time 6) push the crown back in. If all actions described do not work, you will have to visit your nearest watch repair shop and ask to refit chronograph hand as in this case it is out of balance (not pointed at exact mark).
I would take it back. I know from purchasing an Insignia LCD from them a while back, the TV just died after about 4 or 5 months. They ended up offering me another TV or with store credit. I took the store credit and chose another TV. I also did not have a warranty. I was told since it was Insignia (which is a Best Buy house brand) that replacing it was not a problem. Good luck.
Norcent PT4233 no picture, black screen, but has sound. How to repair
The display (PDP - Plasma Display Panel) at the heart of this unit is a LG 42V7 model. There is a known bad solder "defect" on the YSUS board that causes this board to fall unexpectedly.
The bad news is that you have to replace all the primary boards on the display - ZSUS, YSUS and CTRL boards, as the failure can/often takes them all out.
The good news is that LG makes a repair kit for this panel. Its part number is 687VSNB03E and it contains the three boards LG6871QYH036D (Y SUSTAIN), LG6871QZH041B (Z SUSTAIN) and LG6871QCH053G (CTRL).
