May need to readjust voltages to the PDP. be sure to copy the original settings before you adjust any of them as you will need this reference point. If that doesn't help may need X or Y PCB. as last resort the PDP itself may be the fault.

My suggestion would be to go the section marked TV repair, not vacuum repairs.

The only solution to this problem is to have a technician look at it. Sounds like your TV may be going out. Not Good.

You may want to check the power supply. This is an internal power supply so I recommend you take the unit to a qualified technician.

Sounds like you have it in the 4x3 format where it is closed on both sides several inches.

If it has a Aspect button on the remote or the set use that. Note that some cable or sat boxes will format some channels in this format, cannot do nothing with that.

Unless you get an original remote you do not have much of chance to change the format, a few sets have a button or you can enter the menu manually but not many.

If you cannot call around and have a tech come out and hook everything up right the first time. The more equipment you have the harder it gets to figure out what needs to go where.

Quite frankly, alot of times a TV like this can be replaced cheaper than it can be fixed.

This board is called T'Con board, [Timing Control Board]. Just try this link and see its picture.

Good luck, parts are not marked as they are not sold and they do not want a board fixed, they want you to buy another one.

I have a copy of the supplement service manual that has an instructions on how to reset the unit to factory settings (Page 15). You need to make your remote control as "service remote control" to perform the reset. It has an illustration on how to make it. Email me at [email protected], I will send you the copy.

Good day!!

That problem is usually cause of bad/faulty capacitors on the power supply board..So you have a better chances and easily locating the faulty capacitors if it is look like leak/bulged on the top..

So please try to follow this instruction on how to do that..

1. Open the back cover of your TV.

2. Look at the power supply board..Its normally connected to the power cord..

3. After that,,try to look at the actual image of capacitors if it is bulged on the top so that you can easily determine the bad capacitors..

4. After that,,try to replaced the bad capacitors using soldering iron and soldering lead..replaced the capacitors only with the same type ratings and value..

5. Some of the capacitors not bulged so its better if have a capacitance meter..

Hope it helped..
Thanks for using fixya...

Plasma and LCD TV sets are prone to having capacitors in the power supply section fail. This is the most likely cause for the probem you describe. When capacitors fail your will commonly see one or more of the following symptoms.
  • No video, Power light is on or blinking.
  • TV is making a clicking noise.
  • TV takes a while to come on
  • Screen is very dim or flickers.

Again, You can get a power supply repair kit with the parts, detailed instructions, and support from sites such as . Or just click here to see more details on their kit.

Here are pictures of capacitors...Notice that the ones below look bloated. They have failed and will need to be repalced.

Capacitor being replaced! Fairly easy DIY fix.

the 1inch black line is either a buffer board gone bad or the ribbon cable from the plasma screen to the buffer board, the snowy picture could be many things, including y-sus, xsus or tuner boards

Hello - The fact is that your TV, as a HDTV ready device, is really a display monitor that does not contain any TV tuner. There is no place to attach your coax TV connector.

To view TV on the unit you would have to either subscribe to cable or satellite TV service or buy yourself an external TV tuner such as listed HERE (I'm not recommending this tuner just showing the kind of device you would need.)

Regards and thank you for using Fix Ya.
