Question about Projection Televisions
When I plug in the power, the relays click on then off. Some times I can plug it in, hit the power button and get the same results. I have pulled the power supply board and checked and resoldered cold connections. Found 1 cracked soldier, but it still does the same.
This is manufactured in 4-92 , model sd-p5065 pioneer.
I can't find an online manual. I have a little knowhow of the basics. I can't see any burnt capasitors or popped resistors, but if I could get help to test volt and ohlm levels, and led in the right direction, I think it would be doable.
I'm trying to get this working to hook it up as a dedicted gaming tv.
Please advise. Larry firstname.lastname@example.org
Good hints Paul, I had him on Live Chat for a while but lost him somewhere. We parted with him checking the HOuts off board since he has access to a soldering iron and a desolderer. I have initially briefed him on the B-C-E forward and reverse testing as well as the possibility of the B-E resistor and C-E shunt diode which might throw him off.
Any developments with your unit?

Hi i tried answering your chat session but didnt answer quick enough the best place to look is near where the power lead goes into the telly where it goes into the board you will find transistors these will need checking as the do cause the kind of problem your having so check these you can find out the sort of readings you should get by using search engine and type in testing transistors this should give you some sort of idea on what results you should get ok.
Also have you typed in schematics for (then give make and model )see if this locates the schematics for your telly often this helps and does find them i have came across all the ones i need this way
