Question about Sony KP-51WS510 51" Rear Projection HDTV-Ready Television
I've checked the pico fuses(PF80001 ~ PF80006), they all show ~ 5 ohm, seems ok. (my ohm meter probes pos & neg touched showed 5 ohm).
And I also checked two TPs(+22V and -22V), the +22V showed +32V and the -22V showed -6V ...
Any idea ?
Should I replace a new "D" board ? but I don't know how to remove the two red wires(they seem for high voltages, and they connect to a gray plastics box and the box soldered to the board)
Hey man, I have some possible solutions for you, I had a similar problem. Can you please e-mail me at firstname.lastname@example.org?
We can chat.
Also, I would REALLY REALLY appreciate it if you could give me a few service menu values your TV displays. I have an idiot cousin who tried to converge and messed some things up and didn't write down defaults.

You should get service manual and new ohm meter to check parts.
If tools are no good, results will not be good in any case.
I do not compromise on tools quality.
D board replacement is so early decision. As I told you, +22 and -22 should be available in D board. If such voltages are not there, how can convergence ICs carry out the job?
Please have service manual on any online manual store and check power supply area, why +22 and -22 are not being supplied.
Pico fuses should be checked out of board or at least one pin should be unsold to test fuse.
In circuit test of fuse is not good idea and can misguide you with wrong results.
