Convergence Problem???

[trgovic]

I have a 4.5 year old Hitachi 53fdx20b. I am having some picture problems. On the right half and across the whole bottom 6 inches, there is a red ghost shadow to everything. Am i right in assuming it's a convergence issue? I read your posts (which are great) and belive i need a repair kit X480297. Is this the right part? All the links you supplied of distributors that carry this dont have a description of what is included. Would this be all i need? Is repair easy? Please help with any advice. Thank you for everything.

There is no way for anyone to know if this is all that you need. You could have problems in other areas such as the DCU. The reasonable service procedure at this point would be to replace the chips and resistors, align the set, and find out if that solves the problem. Be sure to verify that the resistors are the correct ones for your set. The kit comes with a sheet that specifies the model number. I believe the info I posted to be correct, but you should verify with the distributor that this is the correct kit for your set and verify it again with the info that Hitachi provides in the package.

I have ordered the parts. I am gonna attempt to repair this myself. How would i find out about how to align the set? All i have is "magic focus". Is there some other way, like a setup menu i can access, or will the magic focus be fine?

Basic and generic Hitachi info is available at

I am not too much of the soldering type. Is it ok for me to just replace the chips and not the resistors, or do they have to be done together? I was thinking of trying the chips only first, then if that doesn't work try the resistors. Also, do i need to replace all the resistors or is there a way to tell which ones are bad? Thanks for all your help.

You need to replace the resistors that show any heat damage or are open. You do not need to replace them all.

well, i just finished replacing the only resistor that looked bad (rk58). when i plugged the tv back in, it blew again. it smoked and looked a little brown. i think it is out of my hands now. i have two authorized hitachi repairmen in my area. does anyone know of any reasonable people in the pittsburgh area? should i worry if they are authorized or not??? thanx for everyones help!!

Hitachi is one of the few that has open support to any shop that registers with them. Just ask if they are registered on the Hitachi site. If they don't know are are confused by the question, go somewhere else.

Did you change the ICs? Perhaps you missed a resistor or forgot to connect something?
