I changed my two IC chips and three resistances on my Hitachi TV to fix color alignments. Now the problems is that yellow and blue double image are seen at the bottom of my screen with no much effect on...

Ur tv still have dead resistors parts,test all 12 resistors parts around the 2 STK convergence ICS and changes some more dead resistors parts or changes all 12 resistors parts for sure.If tv still have the same problems after tested and replaces more resistors parts or all 12 resistors parts.Than some how when u handling and replacing the 2 STK convergence ICS and resoldering the 2 STK covergence ICS u short it out the 2 STK convergence ICS by resoldering without proper grounding ur self not to allow for static electricity to kill the 2 STK convergence ICS or u using a soldering iron to high of a wattage for doing soldering ICS work.

Seems two be out of focus with green and red blurr.

The convergence board is what is bad, the Convergence IC need changed out on the convergence board, or the convergence board itself, and you you can also check for blown fuse on the convergence board. The repairs are going to run around 450 on getting it repaired. The red, green, and blue color are alien through the menu, but if they don't line up, it needs repair.

Tv have a problems known as a convergence problems,it dead.Colors lines R,G,B mis alignment,have colors shadows or 3D pictures.The tv convergence board the 2 STK convergence ICS and some or all it resistors are dead.These parts are dead,must be replaced on the tv convergence board to repair the convergence problems.The shop,will cost u $300,350 for parts and labors.

Color out of line i looks 3d in a fake way

the convergence ic of your tv is place at the main board.It is a two big ic that is soldered to the PCB with heat sink. To replace it you need to use a soldering iron ,soldering pump and a screw diver..unsolder it to the PCB replace it with a new one.Apply a silicon compound at the back of the IC before screwing it to the heat sink.

good luck hope this helps..

please rate my help

The picture is clear but every thing has a blue shadow effect and all writing has the shadow about 2" under it.

Your problem is the blue convergence IC has failed, there are two convergence IC's in this unit and I recommend you have both replaced because if one has failed the other is not far behind, better to do preventive measures now then later. One IC controls the Blue and the other controls the Red and Green convergence.

Hitachi Model# 43FDX01B is doing a double image.

You have a convergence problem, you will need to change the convergence IC's STK392-110, there is also 12 6.8 1w resistors that need to be changed, there is also 2 fusilbe resistors that may be open. You can probably Google the IC's as a kit and find them all in one kit.
You can fix this yourself and save about $300-$400 in repair bills.

Convergence issue; red 3D effect. In grid convergence mode blue will converge w/green fixed lines and red horizontal will but the verticle red will not adjust far enough left to converge. has ajustment...

Convergence is dead.Must know how to solders?Must replaced ICS and all of it resistors.Tries Tv repair, for a convergence kit.The shop will cost u $300 for parts and labors.

Hitachi 43FDX01B green is out of whack

The green is not adjustable in the customer menu because it is considered the 'master' color. It is adjustable in the technician mode however but if it is curved it won't even adjust properly that way either. The problem is the convergence ampifier responsible for green convergence has failed. The convergence output IC's need to be replaced.

It sounds like you are going to need to have the convergence IC's replaced. Not really a hard job, but the job requires the proper tools, soldering skills, and a service manual to get the proper part numbers and to perform convergence alighnment in the service menu after the IC's are replaced. Good Luck
