Hi
I have a Toshiba TV MDL40RV525U that flickers for a while when turned on
and after a while it settles down, it gets worse every time I turn it on,
I'm thinking power supply.
Thanks for any advice I can get.

Assuming its LCD can you feed a "black" signal in , to check whether its
backlight problem



The very first thing to check is the state of the electrolytics on the power
supply. If you are lucky, you might see one or two that are bulging a
little, but often, it's necessary to check them all with an ESR meter. Be
especially vigilant of any that are mounted close to any heatsinks. I'm not
familiar with that exact model, but many Tosh's used variations of the
Vestel 17PW xxx series power supplies. If it is one of those, it usually has
it silk-screened in the bottom right corner
