I haven't had any issues reported to me regarding any incompatibilites with samsung TVs. Also our equipment is compatible with almost any TV so my bet would be that it's compatible, you may check Samsung's website as well.

The capitors on the back might be bad this I have fixed on these tv's many times. That could be one of the problems and the capitors are on the power board inside the tv. If you do not know how to work on electronics I would have a pro do it they contain hight voltage so be careful if you try to fix it yourself.thanks

You should have to contact the authorized service centre for Samsung in this case. Plasma screens are not available by open electronic spare part market. Gopakumar Gopalan Google

FixYa expert monitors advised me to not give people this advice, but I am a TV repair specialist with pretty solid experience in LCD and plasma TVs and there is only one good advice I can give for those cases.

So I am a bit in a conflict here as the website managers asked me not to tell people what I know is the best.

So I won't.

I am not telling you to replace the TV and I am NOT telling you to not waste time trying to fix this.

There...I didn't say it!

BTW the hiding and re-appearance of the line(s) had really nothing to do with the cable at the back; it had more to do with you applying physical pressure to the TV frame, something that may yield some result even now, but it can't be used to successfuly restore functionality in long run.

Do you have video? Start with making sure the "Mute" feature isn't turned on. Also check the menu, some sets give you the option to turn off the internal audio !!!

Check its speaker/s first. If found OK, check and replace damaged component/s at its audio output section circuit. If you wish to get some details, check this link. http://electronicshelponline.blogspot.com/ Selecting the view option, either to Mosaic / Timeslide / Flipcard, can be selected by the drop-down list, at the top left of the display window, will make surf easy. You can also do a search, by type in the brand name / model number / IC used, in the search box at the top right of the display window.
