This is from poloroid tv tda-03211c
boy am i lost here... what i did, spent 3 hours reading every post about this IPOS 150 power supply can't get it going..I gotta be close
1) power up tv ...red led not lit on ps board or front of tv..really dead
2)press power on tv....still dead
3)check ps volts on com3...see below
4)check f1 and f2 =good
5)re-solder all old conections and parts
6)checked D10 and D2
7)changed alll capasitors
8)used 2 AA batteries in series to give STB 3V ...I read that someplace. dead..still
9)bridge is good ot 5volts
10)got 7 large transisters or voltage regulators...not sure how to test
11)voltage across main cap is 167v with com3 un-plugged .....plugged in its 320v
only thing the 2 large capasitors are 47uf 450v should be 10uf 450v...someone changed them...would that matter? part of the backlight stage?
STB =0
5VSB =5V
5V =0
20V =0
do have 5Volts dc... somethings alive...
got some pics of the board
I hate to buy a board...thats cheating and no fun
Thanks for any help david
