Static on 50

If you have warranty left- replace it.

What is a static screen?

Hook the DVD to another TV set, this will prove if the player is the issue or original TV

if its old non hdmi forget it blu ray demands to high ?

sounds like a splitter problem try replacing splitters

Hi yes i had the same problem and its basically because the tv needs a software upgrade. I contacted argos and they sent an engineer to sort it and he plugged something into the back of the tv to upgrade it. all in all it took 5 mins to do and not had a problem since.

i have had to replace the hdmi input board on these units to fix them.

Yes the diffusion problem on your tv is due to the pdp panel aging. What you can try is readjusting the VSCAN voltage, there is a test point marked VSCAN using a DVM you can first check the voltage, should be around -- 190 turn the adjustment counter clockwise this should reduce the voltage, watcthing the picture turn control untill the sparkling pixels stop. That should do it. The panel is starting to age this may occur again until you can't adjust it out meaning a bad panel.

If you have static siugnal, sure TV is not dead.

Check the aerial cable, ensure it is well plugged in and getting signal.

If you are using a receiver box, check cables to TV and receiver (freeview, sat, cable etc.), try setting channels on receiver again, if it does not work but you get static, then either the cables or receiver are defective.

Test the TV on standalone , connecting it to an external antenna.
Tune again the channels, and save the preset.
If still no signal then the antenna socket on the TV may be defective.

Try using the TV with a DVD.

If you can watch DVDs, and TV is not keeping channels preset, and you tried all the above, at this point htere may be a fault in the tuner card inside tv.

Call the phone number listed on tv user manual to get support, and eventually repair it.

Is this when you are watching a DVD, or Tape, or when watching TV using the Combo's tuner? The effect you describe is caused by the video signal losing its DC level.
Hope Ya Fix it.
