Re: Philips 42" 42PFL5432D/37 power light no picture please help
I have a red light when plugged in when button is pushed i get a green light.
No picture, I have tested all caps and replaced bad ones. Have replaced Q901 that tested bad and replaced D912 which was shorted. Fuse F901 which blew several times but is ok now. Replaced IC910 which had tested bad.
I don't have 24v to vbl. Is there a chance that transformer T905 is bad? I read .01 ohms to ground on legs 9,8,7. If anyone has a idea of what i should check next PLEASE let me know.Leave a comment:
