Question about Televison & Video
Hi, Recently i have noticed that i have alot of what i would call " fizzing " of the pixels on my screen, especially when the screen has something dark coloured on it. The pixels seem to flash and appear to be moving constantly? If i turn off the tv for 30 mins or so, then turn back on, everything appears normal, then gradually the pixels start to " fizz ". Have you any idea what could cause such a problem? I dont want to go to the hassle or cost of having an engineer come in and then teel me it's interference from something else in the house, is this likely? Thanks, Walter Cairns.
I have encounterd a simular problem with sets like this. THere are voltages called va and vs voltages that have to be certain levels. when the set warms up thes voltage change and causes the symptoms you decscribe. ussally there is a sticker in these plasma that list what these voltages should be it is relative to the type of panel used in the set.. example the one im looking at right now is va=72 volts vs=175 volts.. there a mini pot adjustment that can be used to adjust these and sometime it might help. WARNING .any adjustment made to set can potentially cause more problems and should not be atempted by non technicians.
