Bad Convergence circuit board

I was told by my TV repairman that I could not get a convergence circuit board for my Mitsubishi's (model #V550805) 50 in. TV.
Is this true? Are there any rebuilt one's out there?

Red and green doubled words on tv is this a bulb problem


No, it is convergence problem due to convergence output chips failure in rear projection tv.
Local tv repairman will fix it because it requires soldering work to replace bad chips in circuit board.
Thanks.

Red distorted color near top of screen not having much luck with trying to converge the lines on the tv set form. already tried factory reset


Reset will not cure a convergence problem.

this model (ws-65711) uses a single convergence chip located on the middle circuit board (see photo).

If convergence is skewed and will not adjust in customer menu the chip needs to be replaced.

Good news: I have start to finish, step by step instructions for this repair in this set. They tell you everything you will need and exactly how to do the repair.

No two sets with convergence problems will look exactly the same but I will also attach a few photos of this kind of trouble.

If the photos or what I have told you told you something you did not know and you want the instructions (free) rate this solution as very helpful as I do this here for free.

I was told by a repairman that my convergence module is bad on my ws 55511 or best buy model ws b55 was wondering what a convergence module cost. my power went off and when it came on the red images were...


Any shop with experience should be able to replace the convergence ICs which are the likely problem. This type of repair will cost less than the boaqrd replacment and won't require a conmplete reconvergence adjustment. The parts cost around $25-$40 each (there are 2).

I would look for someone that is able to change the ICs rather than the entire board.

Boe in blue dynamic convergence curcuitry. Swapped deflection yoke on two tubes but problem still remains. Unplugged convergence plug on yoke and bow disappeared but unable to adjust dynamic convergence....


what's the number of the board where you unplugged the conv yoke, should start with 930_ that is the board you need. Try the partstore.com with the part number or type in the brand and model when you have the number on the board, and they display price and availability.

PCL5415R conv. board problem. Having trouble finding part number. I have the manual Samsung


I'll take a look if you want to forward them to me:
freetek@lycos.com
This convergence board problem seems to be very common and if they are not too model specific (firmware embedded) there may be service companies repairing them. I don't; haven't done a whole lot of service for years partially due to the difficulty of trying to pry stuff out of the hands (or shelves) of Asia.
