I see so many here with no sound/nopicture issues:ISSUES: 1. IF sound main fuse/s are good.2. If no power or standby check main fuse, standby power supply and any signsof damage you can see---burnt parts etc.3. almost all these sets the troubleshooting involves checking voltages on the main power board to narrow down theproblem.4. Be safe and if you do not know what you are doing don't open the set.Answers to issues:1. RE:fuses---if a blown fuse is found get a good replacement(not the genericones like Radio Shack). Many fuses are special even aside from amperage--Don'tput a higher rated amperage fuse in the set for any reason.2. RE: power supply in set: if total dead aside from main fuse the set uses astandby power supply that runs 7/24 and a main supply (some are combined andsome not.Here aside from checking fuses you want to examine all the filter caps on thepower/standby to see if any are puffed up or buldged up in some fashion--Iattach a photo of a good one---top should be silver metal and PERFECTLY flatand have no brown material coming out on top or bottom.What happens in the standby area is they use caps with too low a voltage rating(saves money) which causes them to fail in a year or two---the standby runs7/24 and the heat dries out the caps and they fail.3. Trouble shooting consists of the above and then at some point you have tobuy and try a board to see if it fixes it or not.4. Safety first--no TV set is worth getting injured or even killed over.

What is the exact model number to your HP Plasma display? What problems do you face with it? Please give me these details by Fixya comment box. OK

Hi Willianette nice to work with you here in fixya..Actually that problem is usually have 3 causes its either Ysustain,logic/controller or XY board..But commonly need to replace it all that's why plasma TV is very expensive to repair..I have some question for you to help me diagnose your TV..

1. Do you have multimeter and know how to use it?
2. Did you any electronic background?
3. Did you measure the VS and VA voltage on power supply inside your TV..If that so what is the actual reading?

Please answer those questions to help me to fix your TV..Regards,Rossiel

Did it used to work and stopped? I'm ruling out the obvious, replacing the batteries. I would check the Device Manager to see if when you insert the mouse's receiver USB plug, that the device is recognized, and also the driver is properly working. I'm guessing you tried that already... Last resort I would open the mouse and look for any problems with the hardware, and also see if the USB plug is disconnected on the inside. It's also possible for a USB port to "burn up" the trace on the board. This happened to mine for the ports on the top and also thought it was my mouse. I found out that the USB port inside the computer on the top were shorting out the small circuit board. So What I did was remove the small circuit board for the USB ports, and solder in a jumper wire to bridge the gap that was burned out. The cause, dust. I recommend blowing out the case every 3-5 months while it is unplugged with either duster or a compressed air gun preferably. I hope this helps you.
