60pp9352 convergence ic replaced multi points corrected but image squeezed

Hi

I have a 60pp9352 I replaced the convergence ic chips didn't see any resistors blown. fixed multi points but now colors are fine but the image is squeezed on the screen like a bowing on all four sides..

    thank you I'll check them out

    Hi



    I checked the resistors around the board with the Ic chips. the the 6.8 ohm resistors were ALL giving me a reading of 2 ohm on my multimeter I had it set to X10 I did't take a leg out of the circuit I touched the probes to opposit sides if the resistors. do you think I shoudl change all of them?

  • gore308 Mar 28, 2008

    seem like alot work to check . do you recomend a good place to start example the ones cloest to the IC chip?

  • gore308 Mar 28, 2008

    also do you know the volts on these?



    thank you

  • gore308 Mar 28, 2008

    thanks again I appreicate it.

  • gore308 Mar 29, 2008

    Ok



    it is the 30 ohm's that are bad they only sell 33ohm in my area

    Can I use those instead?

  • gore308 Mar 29, 2008

    2 15 ohm ?is that just tieing them togeather or do I have make asome type of bridge.



    thanks again

One of the resistors must be open, you cant always tell by looking if theyre open you have to remove one leg out of circuit then test them for resistance they can only be 5% out of tolerance, any more than that and they must be replaced.

    Let me know if you need any further assistance with your set.

    you will have to remove 1 leg of the resistor out of circuit to check them so you are not getting a reading from the resistance in the circuit. Cause even a blown resistor can register resistance in circuit.

    Just check the 6.8 ohm resistors next to the ICs those are the ones that will affect the convergence.

    No use only a 30ohm resistor, However if you cant find a 30ohm you can use 2 15ohm and hook them together in series. or 3 10 ohms in series any combination to arrive at 30 ohm. A 33 ohm will only burn another componnent .

    they have to be hooked in series to add up the values. Just hook them end to end in line like a string.

Double image, red is 2 inches off main image. convergance ic amp?


Yes, your Convergence ICs have failed. Replace the STK chips, check fuses and the resistors next to the STK chips. Replace as necessary and re-align via the service menu.

I have a panasonic PT-47wxc43 projection tv. I have green and purple halos coming up from the bottom. The screen has purple and green double images which are worse from the bottom up.


Hi,
This problem is due to convergence output ICs failure and both chips will be replaced to fix the issue.
There are two big black ICs installed with aluminum heat sink on deflection board, these are convergence output ICs and will be replaced to correct the problem, it is common problem of rear projection tv.
Below image of deflection shows ICs (marked in red) that are need to be replaced.
IC number is STK392-110 and available with Part Store for $32 each.
Click above link to see an image of IC.
If you are handy with electronics stuff repair and can replace parts in tv circuit board then can replace these parts yourself or ask local tech to help you.
Hope these info will help you.
Let me know if you have additional question.
Thanks.

Multi- color bands - twisting wave pattern cross the middle of screen and can not get image to lock -flickers both horizonal andf vertical. Would this be the same 2 IC chips- last time i had this problem...


Ur tv have convergence problems,it dead.U must have soldering tools,solders and know how to solders to fix convergence problems.U must replaced 2 STk convergence ICS,and some or all it resistors.Tries websites Tvrepairworld.com,Tvrepairkits.com to buy a convergence kit to repair it ur self.The shop will cost U $300-$350 for parts and labors.

Convergence problem with Philips 60PP9352




You have a convergence problem. Here are some of the most common symptoms. 

Screen looks 3D
One or more colors can't be adjusted when when using the convergence menu. 
Screen is bowed in but stationary.

Solution: 
You need to replace the convergence chips and convergence resistors. Check the site www.TvRepairKits.com. They have put together a kit for your exact model. The kit inlcludes a photo instruction guide, original Sanyo STK chips, convergence resistors, etc. Everything you need to fix it yourself. Its an easy fix.

60PP9352 60 in. Rear - Blue convergence issue


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.
