Well Dr. Hitachi has a sequence of L.E.D lights in back of set that lights up in accordance to what is wrong with set. there are about 8. so you need to first get someone to turn on and while looking notice which lights up first and goes out first. This tell the tech what is wrong with set. From my experience with Hitachi, I have replaced many Convergence amps which are the big STK's392-*** or something close to this depending on the set. But it most of the time gives some kind of indication before going out. Like color problems not matching up. Red, Blue or Green out of line, mostly on corners of set. If no color problems then next would be sound problems, and vertical problems. Either problem will give a no High Voltage problem like yours. Also it has little pica fuses, sometimes yellow in color. These can be open also. There are many areas to check but if you are willing you can find the problem. Remember to be safe at checking anything with set plugged in. Turn off first. Hope this helps!
