Question about Projection Televisions

1 Answer

I am helping a friend to connect a 60 inch Hitachi Projection screen, model no. 60u85b it says on the back, to a Sony str485 amp that can run 6 devices - to get the sound from cable TV to come out the amp. There is the cable box, the amp, and TV. Some how could not get it to work. Forgive me so being so stupid. I ran the TV cable from the floor to the cable box, and then ran a coxial from the cable box to ANT B (antenna B, I presume). This produces sound from the TV, and was how it was set up before I came on the scene. I think I am not getting the signal from the cable box to the amp. I tried "audio out" on the cable box to "video in" on the amp, then connected the speakers, but have no sound at all. I thought this should have done it. This is where I get lost, I guess. The amp only has one coxail. Should I run the coxial from the cable box to the amp instead of to the TV; then a video out from the amp to a video in on the TV. I haven't tried this yet, because I didn't think of it until I started typing this letter. If so, then I will have another problem. To run a line from the TV, (called) "monitor" to the "monitor on the amp is tricky. The jacks from the TV are 3way RCA, and the jack into the amp is a 1way RCA. Is there such a jack. And would complete the circuit, as it where, of from the ampt to the TV, and then the monitor from the amp to the TV. At my residence,I am currently the cable, so I cannot just look at mine to see how I did it. Have I given you enough information? Can anyone tell me what I am missing? Can anyone help, please? All help is appreciated. Thanks

The coax should go from the wall to the cable box to the TV, just like you have it. Then you should run audio only (L and R RCA) from the cable box (if it has it) to the amp. Don't worry about running a video signal to the amp.

You have a defect in the convergence circuit. Both chips will need replaced and possibly a resistor or two. Chip part numbers are STK392-110. Typical repair runs around $350

I would first check and see if any software updates are out on this set, you can call Hitachi, if not that then it could be the engine assemble having problems.

Hitachi-picture goes out but can still have sound


If it is a Hitachi 60V500 LCD projection TV, then I would suspect the lamp being the problem.
