the set is in shutdown, someone will need to find the defective board and replace it---not a do it yourself job for most people and HP not exactly easy to get parts from.

If the problem is same with different input devices and you have ensured there are no loose contacts in power outlet, RC jack, cable and sockets, the TV needs servicing.

Display or its board has got affected partially and might require the attention of a qualified service technician.

Check its speakers. The audio output section seems to have no fault, according to your description, because, if it has any short, the main system will detect it, and the set wont't switch On, and will switch off after some blinks of standby light.

If your TV is plasma the only part you need to replace or check is y sustain board..You should replace it to work fine again

The problem here is you cannot even find that---I suggest you either buy the y sustain board as only circuit boards are sold and NO parts themselves or take it to a shop for an estimate.

You most certainly do not want to disassemble the tv. HP has made a valid diagnosis, you would be best off taking the replacement board and tv to a repair shop and have them change it for you. Yeah, it may cost a little, but Plasma TVs have very fragile displays- very easily broken.

See this video. It will give you an idea about this work.

You might want to contact [email protected] we are taking action against HP for selling this model tv with known defects. Consumers should have protection against this type of abuse.

Start with checking the fuse/s inside and then voltages on the power board---these are the essential and beginning steps to find the problem.

I hate to be a smart ***, but if you have to ask, you have no business trying.

Usually, when you replace Y-sustain board, for older plasma, they suggest to replace both Ydrive board (up and low). And sometimes, Z-sustaint. Im not sure your are an expertise in this matter so be very careful when you open a TV because hasardous voltages can kill you in the worst escenario.If you are not, don't work on your TV. It will be your sole responsibility.Check ships on Y drive board (both board are installed on the right side of Y-sustain. They have square black ships that used to get bad. If they don't have aluminum cooler on them, you can see if they are burned or have holes on them. Old plasmas use to have issues with those boards. Before you installed the Y Sustain you should check Ydrive boards. Maybe you damage the Y Sustain because the Y drives weren't good. Try to replace the fuse, disconnect the Ydrive from Y Sustain, turn on TV and check for voltages on Y sustain (panel has a sticker with each voltage). Hope you didn't damage Y sustain and can find Ydrive board to fix your TV.And REMEMBER, you can kill yourself when you work on TVs.
