I have a similar pblm. But your first step is to power on with tv's button. Look into the back through holes and look for 4 green and 1 red LEDs lit. If not there are 3 fuses on the power supply board.Fuses can be easily changed.
next step call service.

Our hitachi 43fwx20b has double vision any ideas?


Yes, set uses two convergence chips, either STK-392-110 OR 120.

Both will need be replaced, I have photos and instructions if you tell me how much skill you have.

Let me know if I can help you, parts cost on EBAY under 20 dollars.

Good Day, firstshot;

This is a common problem with this TV, but there is an upgrade to correct the CONVERVGENCE circuit problem.
If you want to repair this concern yourself: Contact: B&D ENTERPRISES,

Picture problem


Most likely there is a strong possiblity that the vertical scan amplifier for the observed colour channel is starting to fail. An experienced TV tech who works on your model type can fix this.

Any fault is fixable. It is a question of the amount you are willing to spend, and the avialability of parts from the manufacture.
