Title: Hitachi 20LD2500 with A Vestel 17MB18-5
Post by: litemoth on March 07, 2010,14:52:30

Hi all,

I'm trying to repair my mum's TV - It's developed a verical white stripe about 2" from the right hand side of the screen - the menu graphics are confused and lined. The TV picture is washed out and shifted left. picture colour is washed out - backlight seems ok.

I cant seem to find much mention of this board or TV, so I'm a bit lost. I'd be grateful for any pointers.

 :wacko:

Picture shifted left with a dreary picture - as if the number of colours available have been drastically reduced - you can see boundaries to the colour zones

Did you try to put an empty memory. I think is a software fault, try to put empty or find proper memory dump. Did you try to make factory reste in SM of TV ?? Regards

Try  menu and 4725. Look for factory reset, don't change anything else. Regards

Menu and 4725 will not bring a Factory Reset, this will bring you to Service Menu where can be performed Factory Reset. Regards
