Unhappy rpjtv's

Hi,videonut here,i have a problem with a 55inch phillips rpjtv that will not come on.
What i had to start with was it would power up,then the picture would change sizes several
times then it would get what i would call a waist,now it will not power up at all,i was thinking
it maybe a power supply as i remember something like this years ago,right now i can't afford
a new one but if someone on site can steer me in the right direction or have some ideas that
would be helpful it would be appreciated,thank's

Probably a bad logic board.
"Fully on MOSFET = closed switch, Fully off MOSFET = open switch, Half on MOSFET = poor imitation of Tiffany Yep." - also applies to IGBTs!

Hi, star 882, i got your post looked up logic board,found some on ebay but i have not been
able to nail down part # just yet,but it appears that these are not too expensive so i might
be able to afford to take it to a shop to be fixed,right now i am rooting around for a repair
manual,thank's for the info
