Question about Hitachi 53SWX12B 53" Rear Projection Television

1 Answer

Amps and resistors

I replaced the 3 resistors and the convergance amps on the Hitchi 53 in ultravision (rear projection). But I noticed a problem when I soldered the amps in place that I bridged one of the solder joints, I plugged the tv and nothing happened so I rechecked and desoldered the bridge joint and still no picture. Are there fuses that go when this happens or is the amps no good again. ANY HELP Thanks

The IC is no doubt bad due to powering it up with the solder bridge. may possibly need entire convergence board unless you have the service manual and troubleshoot it.

Hitachi ultravision rear progection converge


If the convergence is so far out that you cannot adjust with your customer access menu then You will probably need the convergence ICs replaced & possibly a fuse or resistor or 2. Then a complete convergence will be necessary & I HIGHLY recommend having a professional technician perform this task.

Picture problem


the problem is convergance the amplifiers (two of them) have failed. posibly some resistors or pico fuses are bad along with them. they need to be replaced then realiegn the convegance. the cost of repair may be $200.00 to $350.00 depending on the tech you get.
