Most times with this happens you can repair it by replacing the buffer bds. Sometime the ysus bd is bad and unfortunately the panel can cause this problem. I would say 60% of the time the buffers will correct the problem. I usually replace both at the same time.

I have a samsung plasma tv that the picture color is wonky any ideas to fix??

Sounds like the panel is shot. That happened on a Toshiba I had. If the voltages are good, then its the panel.

Samsung Plasma ps-42s5h has two black lines running vertical with green strip in the middle

Ok we have to resolve the extent of the problem before diagnosing it. Does the black line/green bar show on all inputs and the tuner? Is it visible in the OSD (on screen display)? if yes to all of these questions, it could be a panel drive problem or a bad plasma panel. A picture would help diagnosis

Samsung hps5053 sound but not picture 50 inch plasma has sound but no picture

I have the same model with the same problem. I resolved it by changing energy saving from Auto to Standard. There is another option for Super Saving which I did not try. You can find the option by holding the Exit button for 10 second and you should see the setup menu. Go find the setting and change it to Standard and see if that will solve your problem. I bought this 4 or 5 years ago and this is the first time I have this trouble. Good luck to you.

Check the relay you might have a bad relay board. Also check other things like decoder board. I am sure you might have a stuck relay. its hard to tell behind email.

Snowy color screen & have sound

On the back of th panel are list Vs, Va voltages. Find the test point on the power brd. Labeled on one of the connectors. See if voltages match. If they are slightly off find coresponding trimmers and adj. if way off disconnect x and y sustain boards from power board. if stays low then replaced power board. if it is normal with x,y disconnected then one of sustain boards. if voltages all ok suspect panel. ry checking other inuts first to see if this is a vseo problem or not.

No picture

Common faults that give you no picture and sound on Plasma are often related to Sustain board, buffer and cables problem.

In this case the cost will be affordable, ans surely worth.

In the unlikely eventuality that instead you have a faulty plasma screen , or a faulty digital control board (main board), the cost of repair may be high.

The only way to find out is by having the TV inspected by a technician.

The most common fault that gives you no picture and sound on plasma is Sustain board , lower buffer, or connector, that is repairable.
