Question about Hitachi FDX Series 43FDX10B 43" Rear Projection Television
I had my tv worked on two mts ago the repair man put something on my circuit board then he had to take my tv to his house to reset now its doing the same thing my husband took the back off and it has a red light showing up on the middle circuit board
There is a board on the right side of the tv called the convergence bd
There are little connectors that are on the left of the board
the last one is the power to the convergence Ic's
That is the one that is closest to you. they are little black conectors with wires in them
Carefully lift it up
Then plug the tv back in and see if it fires up
If it does do not run it long
just enogh to see the tubes light
then shut if off
If it goes on
your convergence ic's are Shorted
They have a kit for this tv it is available through local parts distributors
If you can't find it locally just Google HITACHI CONVERGENCE KIT
If you are not good with de-soldering and soldering do not attempt this repair. Remember to replace all the resistors in the kit
If you are not sure about doing this repair you should have your local tv guy do it for you
If it does not go on then I would suspect the regulator in the power supply But
Most of the time it's the ics
