Blue shift on Mistubishi WS55411

U used every components,that came with that kit?Grounding ur self.Used a low wattage soldering iron resoldering the convergence ICS again,no matter what the resistors are in torrence or not replaced all of the resistors,still have the same problems.The 2 convergence ICS got to much heat and stastic ectricity charges it it shorted and kill the 2 convergnce ICs.

bmarino18,

Initially I would have told you to replace the convergence ICs but after reading your post carefully I think you could have a problem with the convergence box. The lines can only be bent/curved for two reasons. One - the yokes are bad causing an undue strain on the power supply and not being able to correct the problem. Two - the convergence box/board is bad and is not holding the settings causing the curve you see. I cannot tell you which problem you have. You wil have to determine this. I do have a tip at http://www.fixya.com/support/r4273935-replace_digital_convergence_box which may be helpful.

Thanks for using FixYa and for the great rating.

Thats the classic sign of failed convergence ICs and resistors. You can get the convergence repair kit for your model at www.tvrepairworld.com the kit contains the parts and the Cd with instructions.

It seems the solder is broken in Vertical Convergence Amplifiers or it is damage internally. This model has 2 Conv. Amps: 1 for Horizontal (Red, Green and Blue) and 1 for Vertical Convergence output (Red, Green and Blue), if the convergence does curve at the top and bottom, it is because Vertical Converegence output is no good. The Conv. Amp. costs around 20 dlls. Thats why you can not fix it with the Menu option. Good luck!

CHECK FOR THE SUFECE MOUNT CAPACITORS AT THE SMALL CONVERGENCE CIRCUIT BOARD

You have a hardware problem, you cannot fix it using the menu. in fact you could make it worse.

Try googling DIY convergence repair if you can solder.

If not then call in a pro, about $300

DA, convergence circuit has failed, the IC`s and possibly a couple of support resistors need to be replaced, your right about it being a good set, 6 years is about average for convergence IC`s, call your local shops for a few estimates and get it fixed, it will run for a lot longer than 6 years, hope this is the advice your looking for, e-mail me if you have more questions, BMW Rider

Par 2 = " I do see the convergence chips..."
Par 3 = " I'm not sure where the IC's are...."
Please verify STK part # of IC's on large heatsinks.....
And then I'll give you step-by-step instructions......T.

Set will need new convergence IC's.Requires chassis pull===technical & mechanical skill mandatory.After repair,re-aligment necessary.

Replace both convergence IC's part# STK392-040. Also check for burnt/discolored resistors nearby.
