Question about Philips 60PP9352 60" Rear Projection Television

60PP9352 60 in. Rear - Blue convergence issue

Hi,

I have a problem with my 60PP93 5217 tv. The Blue convergence went wako and is unadjustable through the convergence menu. I've been reading about replacing the STK ic chip and some transistors. I'm not sure if I should just do the Chip, or the transistors, or both. Or maybe I should try the chip first?

Also, do you know the location of the transistors.

I would appreciate any help on the matter.

    Thanks Jaime, This is really helpful.
    Do you happen to know which resistors I need to replace? I may as replace the resistors and like you said do it once.

    Thanks Jaime, So it looks like the best solution is to just do both the chip and resistors. Do you happen to know which resistors I should replace? I haven't open up the back of the set yet.

Replacing only the ICs MAY solve the problem, however, many people have also had blown resistors requiring replacement. Also the convergence board should be checked for cracked solder. If you replace the ICs and the resistors are shot, the ICs may blow again almost immediately, meaning you may have to do the repair twice.
You do not have to replace any transistors to fix this convergence failure.

    I will check the schematic diagram and let you know later about the resistors that might have to be replace if they are damage.

I have Sony KP-46WT500 Projection TV. For some time it appears convergence went bad. I see multiple images, especially at edges and corners. As many as 3 images Red, Blue and Green. I am an Electronics...


Hi,
It would be great to assist you in Sony convergence issue.
As you said, for some time TV shows bad convergence in picture that shows its matter of lose/ dry solder joints in D board, specially on convergence out ICs pins that need to be re-solder.
There are 2 big black ICs mounted on aluminum heat sink on D Board of TV, below image shows D Board location in TV.
Resolder pins of these 2 ICs and also check any other dry/ cold solder joints in circuit board. I do not think of IC replacement as problem occurs some time.
Let me know if you have additional question.
Thanks.

Convergence IC + Resistor swap = Blue light clicking noise


Good Day,
It sounds like you may have slightly diconnected a cable. Look for the large RED cable/wire that goes to the Blue tube and make sure that they are very secure. When doing this make sure the TV is off.

Good Luck, BIG IRISH.

Color convergence problem


If you follow the instructions on the other thread, you should be able to resolve the problem. Try the simple stuff first. Resolder the pins of the convergence ICs and see if that alone resolves the problem. Sometimes that is all it takes.

Keep us posted.

Projection TV wil not cut on.


You should first replace the convergence IC's, both of them. Also make sure all the resistors on the convergence IC's are good and not burnt. That's probably what you smelled burning. Good Luck
