Fix your tv with black screen blinking light, popping sound noise. ... Watch QueueQueue ... TV Black Screen - Repair LCD LED PLASMA - Problems SONY LG .... I have a 60 inch samsung DPL tv how can I stop the humming or ... What do I do if my tvturns on but its just a black screen so sound no picture?.

No--this is called a PDP or plasma display panel and no two (even same brand) can be interchanged.

The cost of a Panel exceeds the cost of a new set--broken screen=fatal issue.

Most likely your Y Sustain panel has gone bad. I would have a qualified service center evaluate it to be sure.

I had the same problem -red, vertical bars along the right side of my Samsung 42" Plasma- and this is what fixed it: Removed unterminated cable.
I had hooked up an HD video camera to the set about two weeks ago. While I disconnected the camera I left the other end of the connector cable plugged into the T.V.. As I've since learned from friends who work in television, this is what's called an "unterminated cable" -meaning one end is unconnected. It can lead to problems with electrical interference and appears to have been the problem in this case; When I disconnected this cable from the T.V. the red bars went away.
So, check your cables. Make sure everything is properly connected and get rid of anything that might be picking up interference.

i just had this same problem with my 42" akai plasma and after getting no help no where i finally figured it out on my own. The model i have is a PDP42Z5TA but my guess it will work with yours also.if your remote is like mine there should be a "set" button somewhere up at the the top.hold this down till the "tv" button goes solid red. with the tv on or off keep pressing the power button till the tv turns on or off( dont go too fast) or you can pass it up easily cause when the tv does turn on or off you have to hit enter to lock it in.

Here are specs for your tv
you need a dvi to hdmi cable similar to this one here
or this for US
ask also to your local reseller.
If your pc does not have dvi output you can try a vga to hdmi converter cable, I do not know if vga one will work on your tv.

Make sure that you haven't pressed input by mistake i.e going onto scart or pc input press TV on the remote and try this.
also check that the scart cable is fully inserted into the TV as well as the digi box or VCR or what ever.

sound no picture. well not entirely bad this idicate your signal getting through and you have partial power. however this could mean that the actuall panel is faulty. if so new set time. What is the model and make of set.

ysus pcb that supplies voltage to the panel is faulty

probably you switch was sticking causing it to behave that way.just monitor you tv if it happen once more then it will be time to call the tech.standby my brother.
