My hitachi 42edt41 42in picture flickers

It does this after it has been on for a while, it will flicker with like green and purple, it almost looks like what happens when a magnet is put next to it, but there is no magnet around.

    Thank you.

    I do have it plugged into a surge protector and it still does this. And i also have no hd components plugged in. IS there a possible way i could get it to go away? or maybe not be as bad?

    The only adjustment in the back that i've done was to fix all the pixels. But i'll have to try the v hold. And im guessing the lamp is about 4 years old or so.

First. Try using a surge protector.
Could also try purchase a HDMI cable that is compatible with 100Hz,

Possible problems:
backlight inverter wearing out

Very Common In The Newer Tv Sets

Tv's have a chemical/molocules called phosphors that can be deentergized when a tv is left on for a long period of time. Not a serious problem but still annoying

    Have you tried any visual adjustments either from your tv's menu screen or by removing the back of the tv, there are knobs. One knob says V-hold. I would try adjusting any settings first.
    how old is the lamp??? this is one of the symptoms of a failing lamp
    Flickering in picture is caused by a leakage current, and hue shift (low output of one CRT) which can only be adjusted by a repairman

Hi, I have a Hitachi 53 UDX that was working perfect and then I turned on my system which turned on the tv which came on, but then screen went out....Now I have a squashed looking oval picture that comes...

Have you checked all of your cables to ensure all are connected properly and are tight? If you disconnect your 'system' (which I'm guessing is an audio system?), does the TV work correctly?

Hitachi 42" plasma 4 yrs old

I have the 55HDS52 and it flickered like crazy. The firmware was V0101.0001 and I called Circuit City and they sent a tech out with the latest fimware for my TV which is V0102.0001 and now the flicker is gone. I kept my settings all the same and watched the same reference scenes over and over and could not get it to flicker anymore. I'll post if anything changes but it seems that this worked for me. please have a look at THIS very long forum on Hitachi Plasma Noise

Hitachi Plasma EDTV has green dots flickering all over screen

that is called diffusion. that can be adjusted out in most cases by adjusting the y sustain pcb but can also be the main pcb, the logic pcb and panel itself but not likely.
