I replaced the two IC (part # 932212344682), but I still have a problem convenging the blue and the picture is concave at the top and bottom. I want to replace the resistor mentioned from other post(6.8 ohm 2 watt)
, but I don't know which one. Can someone please let me know which resistors am I to replace, location, number and color if possible? And where can I get a diagram for my TV Phillips 60PP920217F?
Thanks and appreciate any help.

Re: Phillips 60PP920217F Convergence Problems
Sounds like you are on the right track, yes you need to change also the return resistors, they will be located close to the convergence amps you have replaced. There should be several resistors standing up around the IC's, you can lift one leg and check all resistor and the ones with same color should be the same resistance. Another way is to just replace all of them. I don't have a location for you but I have replaced a similar set 51pp9303h/17 and I think the boards are similar. So if you are this close then by all means replace all the resistors, You can go to MCMelectronics, Bluestar-online.com, Tritronics, etc. To get part and also you can buy schmatics on line. Don't quite remember site but you can search. I think it was 11.99 for downloading for my set. So hope this helps.

thats a problem with the Blue CRTs coolant needing replacement. If you look directly into the blue and green CRTs while its playing you should notice a bunch of crud inside the lens indicating that the coolant needs replacement. You can get the coolant replacement kit for a phillips at the following link which includes the coolant and instructions http://servicemanuals.vstore.ca/
what about blue? this is an indication that maybe one of the convergence ic have failed. generally you replace both. falure of the ic can also be sympton of other problems.. The oputput ic resistors. the covergence power fuses. but the first step is to replace the ics
You will need two STK392-120 Convergence ICs and about 4 6.8 ohm 1watt resistors. You can get replacement ICs and resistors at the following link and they provide free instalation instructions with pictures so you can do the job yourself. Here is the link. http://servicemanuals.vstore.ca/
Are the colors out of alignment and unable to converge back? If so its the convergence ICs need replacing. If the convergence isnt out of alignment you have whats called a pincushion problem. If you would like a link to where you can obtain the service manual for this model let me know.
replace ic chips pt# stk392-120 or stk392- 150 and there are 12 resistors located near ic clips pt# 6r8 ( color code blue - gray - gold - gold ) board location no#s 3149 thu 3160 if you look close you may find two resistors discolored as i found on my convergence circut board , also use heat sink compound on new ic chips , take your time to mark all wire connectors going to board from tv , also use .022 dia gage rosin -core solder and a 15- 25 watt soldering iron you may have to adjust the red - blue convergence afterwards my tv set is 3 yrs old also ( thanks holbert )
