Question about Toshiba 65HM167 65" Projection Television
The power fuse keeps blowing when we connect it to the cable for the satellite. We have tried a 7 amp fuse and a 6.3 amp fuse. Both keep blowing when the cable comes in contact with the television. The cable works fine with other televisions so the cable is not the problem. What could be wrong with the TV?
You have a dangerous situation here---All modern units (Lamps, TV's, everything) Have a polarized power cord---one side of plug the pin is smaller than other side.
The large side goes to the neutral side of the electrical outlet.
One of two things has happened---either a issue with the electrical outlet which is rather rare except in older houses that have the old style electrical outlets (both pins the same size) Or someone has managed to get a cord in backwards--filed down the large lug on the power cord and put it in backwards.
What happens and can be tested is with it backwards you have "potential" 120 volts being fed back into the cable wire itself--
DO NOT KEEP CHANGING THE FUSE--a simple test with a voltmeter set to AC (wall) voltage from a earth ground (water pipe of metal will show 120 volts on the coax.
The touchy part is any set in the house misconnected can feed this back via the coax!
The cable company may be able to help or NOT> an electrician will be able.
The way I would locate this is with the volt meter hooked to the coax I would disconnect the cable feed from each set or unit in the house one at a time until no voltage reading---then you would know which is causing this issue.
Be advised it can spark which can destroy parts in any of the sets or equipment.
Kind of like if you got shocked when you touched the metal on your car.....something bad is happening.
Please if need ANY help comment here and I will assist.

Hi, I am an idependant service engineer, who is currently looking at one of these actually a 36 inch 36zt29b. So far, it looks likely the digital board is at fault sending an 'off' signal to the digital power board. The digital board itself is no longer available. I am going to have a look at this board, and try to fault find it. If I have any success I will post again.
