I have a 48" sony color rear video projector television
model number: KP-48s65
right now my problem is that the television turns on, has sound, but the screen does not display any picture. i took the whole upper body of the tv off to get a good look at all those boards, and chips and things. and i didnt have a clue what i was looking at. but i noticed when the tv is on, that the 3 projectors do have a line the color of the projector in them. i guess its just not bright enough to go on the screen when its together. also my friend said he talked to someone and they said it may be a main switch diode?
i was looking up on some q&a pages for this model tv and it said for that problem it maybe not getting high voltage, or the crt's? are not getting a video drive, or the horizontal output transistor is open. and if thats the case ill have to change that out along with the flyback? and HV divider block.
is most of this right? and if it is any help on telling me what the horizontal output transistor/flyback/HV divider block/main swithc diode look like, and what they look like if they are bad? or even maybe which circuit board they might be on! im sure someones going to come and say if you dont know what your doing blah blah, well i dont know what im doing but im not going to learn paying some body to do it. ide rather try it on my own and either be happy cause i fix it, or not care if i dont. tv was free anyway.
