LN55C650 Side light on right side is out, picture is fine but is just dark on the right side. What PCB do i need to change or what do i need to check to see where the problem lies

Have you double checked the compatibility of the TCON for your brand and model ?
All TCON are not same.

there is a T con error please replace the T con in this condition

Hi, this sound like the same fault as i had, our tv only had half the screen go off also, the right side, after looking up on the internet i found a video for a fix, what you need to do is remove the back cover, there will be ribbons that go from the front screen to the main panel, i removed each one at a time and rubbed the contacts of the ribbon with a rubber on the end of a pencil, plugged them all back in and switched it on and it was now spot on, thats more than a year ago and its still working spot on, hope this helps

I had the same issue occur on my ln55c650 (screen flickering, not the actual image but the front lights flashed which was too distracting) and they had to replace the power supply pc-board. Seems some issue with power module in the TV rather than the side panels. Luckily for me, TV was still in warranty.

You may need a drive PCB. This PCB can cause the picture to be too bright, no brightness or picture too dark, intermittantly or permanantly. Do check the bulb though and see if it is foggy looking or dull especially if it has not been changed. Thanks for using Fixya.

Z-Sustain PCB will cure it.

It is inside the TV, on the Right Hand Side.

www.chsinteractive.co.uk or Google for a replacement.

bad panel

60PL9200D/37 When I unplug it for a while and turn it back on, the picture starts to come on, but it turns dark. And the red lights on the left and right side of the power button blink. Sound but no picture.

the LCD backlight has failed, you will need to replace the LCD assy (about $200)

Assuming you don't have a trailer connector the bulb failure warning module might be you problem
