I had my 42 inch orion plasma for about 1 year when i unplugged a camcorder from the s-video while still playing and about 10 horizontal lines appeared accross the top of the about another year...

Unplugging camcorder haven't damage your set. Looks like you have an issue with you main/signal board. while you pull the plug, you may stress the connections on the board, what about to be happen, anyway.To diagnose and fix plazma you must be an expert, definitely not a beginner. If you want to take a chance of braking the display, you may try to poke it open, face down on soft surface(about 50 screws) and tap on the board with all of plug connections, wile tv is working, but need someone to help you, by holding tv on it's bottom(if there are no speakers) or top.look at the screen and see, if tapping makes a difference. If it is, you've got lucky! If not, surrender to experts.
good luck,

42 inch LG Plasma TV - Lost picture

Most likely what happened is one of the capacitors went bad. When a capacitors goes bad it produces a popping sound. This could be an easy and cheap fix if you find the bad capacitor or capacitors. The bad capacitor will have a bulging top most likely on the power board but could be anywhere.

You need to replace the Y scan board. Sadly, all of the PL4260 models have the same problem... its just a matter of time before it blows. HP has offered a "free fix" but only to those sets that fall with in their so called serial range of those with faulty parts. Like I've said in another post... I called HP yesterday (3 December 08) and they admitted to having used sub standard parts in all of the PL4260 models, not just the serial ranges they (HP) stated.

HP isn't going to fix yours.... and I'm willing to bet your serial falls 1-3 digits outside of the "free fix" serial.

Solution: you will need to purchase TNPA3243AB-PA and TNPA3242-PA to fix your issue. Or you can go ahead and let HP come out and fix your tv for $700+ The difference, you order the parts and fix it yourself...$250-300 plus your time and effort.... you pay HP $700+ for their tech to order the same part from the same distributor, and they put it in for you... either way, you're not getting a warranty or at least thats what they told me....

There are several shutdown circuits on this unit. The X main or Y main are the usual suspects. Call 1-800-Samsung for a qualified servicer in your area.
