samsung lcd tv vertical lines

I have a Samsung LCD TV model LA32S81B. @ 2 yrs old. It has random vertical muticolored lines with no picture, but sound is OK. I know Samsung has been putting in bad caps in their power supplies. This one looks OK. I suspect the panel , or the circuit card at the top of the display is bad. Anyone have similar problems with this TV, or know where I can get a service manual?

Hi edspit

LCD's are notorious for bad joints. Look for any hot spots and cold solder joints to transistors, capacitors and re-solder all of them next to the IC's. Visual inspection of the caps doesn't mean that the caps are good, the have to be tested with a DVOM.

Here's a link for your service manual: https://www.manualsparadise.com/Welcome.do

Great prices and excellent service.
