Question about Zenith IQB50M90W 50" Rear Projection Television

1 Answer

IQB60M90W blue convergence axis rotated.


The three colours converge whereby all three centers of the axis meet. The issue is that the blue colour is rotated by about 5 degrees causing an angled blue shadow. Is this repairable and how do I do it, which part do I buy?

Problems aligning convergence hc-p4753 projection

Hi,if the converence is wildly pinched in say one corner compared to the other colours then it is most likely that your convergence circuits have failed for that colour. - Warning,Not an easy fix without circuit schematics and can also be costly for the IC's too

My LG rear projection TV RE40NZ60RB colour is ghosting with three colours separating. Colour converging does not rectify

There is a problem with the convergence circuit. It can be as simple as poor solder connections at the pins of the convergence IC or a defective IC. If you can solder, you can fix this yourself. Please confirm the model number of hte set and I'll provide the part numbers etc. required to resolve this.

Replace Both of your STKs if they are STK392-110s do not go back with them use STK392-180s better ICs, The 110s fall apart and do not hold up.

Blue colour not centered. Does not respond to convergence. Rest of colour is ok, sound ok. Blue shadow to the right of image.

This could be a defective convergence IC. What is the make and model of the set? If you can post that info, I'll be able to get you more details.

Three colours don't converge

Shrink, the convergence circuit needs to be repaired, Until someone gets in there and takes a few measurements it`s hard to say what the cost will be, may just need to be re-soldered, good luck, BMW Rider

the convergence board has nothing to do with tuning of tv, the convergence board put three colour gun (red, green, blue) to work with each other, else you get three image, of red , green,  blue or mixture of all as seperate image, the convergence board for american tv and Australian tv is possibly the same what you check to see the board  part number is the same you possibly need to see if the convergence board has got the memory i.c. if that is the case, you need to tune you t.v reset the channel etc good luck.
need more help let me know.
