Question about Sony KP-46WT510 46" Rear Projection HDTV
I get momentary high voltage. HV-PROT signal (hv-prot), from A board is bringing it down. I keep horizontal out supply voltage (135V, I believe this is controlled by the high voltage regulator). I just loose drive from protection signal applied by CPU.
Is the voltage staying at 135 volts or is it rising?? There are several power supply fix it kits available as well as a way to test the power supplys. please let me know as I have a nice library of sony kits to use as well as a way to test the power supplys. Also a bad Crt can cause a shutting on and off of a projection set as well. If this is the case, try having the CRT rejuvenated and see what happens. please do not forget tp rate this htread.
