Hello I have a Thomson 50DLY644 chassis ITC250 and some problem with flicker screen i looks like colours are les and more bright. I try strat TV without colour wheel and effect was the picrue black and white but still flashing, another time I tray to start with the another lamp-stil flashing. I'm examined the light source turning the lamp on the wall and lamp lokks fine (no flashing). What I need to tray next, maybe power supply capicitors. I have no ideas. I wonder about the dmd board. Conections with signal board is made by hdmi cable i tray conect with my laptop but the tv' is going down and redlamp on the front panel flash. Have anybody any ideas how to start it? or what is cause of flickering. Sorry for my English

hello,
you are correct this can be a power supply or ballast issue, but if you have not changed the lamp in a while, this might just be a lamp failure, how long has it been since you have replace3d the lamp?

New lamp was pluged 3 weeks ago. By the way I live in Poland an I have big problem with the repleacment parts but I try find new ballast on ebay. If it helps I give Message. Thanks for help.

so you have a new lamp, screen flickers and there's some discoloration? I think this might then be an issue with your colorwheel.


if you still want to take a look at the ballast, here is a link below!

To eliminate colour whell I made follow experiment. I start TV's without colour whell inside of the light tunell but still conected to electronic. Tv's start normally but the pictrue was black and white and the flicker issue was still noticeable.
