Question about Philips 60PP9202 60" Rear Projection HDTV-Ready Television
My TV has a problem with the red and blue convergence and I cannot adjust vertical alligments so it looks like these are shot. Can anyone help? Does anyone know the part numbers of these (IC)units that I would need to repair? I hate to throw this unit away. Thanks Glen
I have the same set and just fixed this problem toinght! I bought a couple of STK392-120s for $20 from www.electronix.com and with a soldering iron, heat sink compound and a solder sucker was able to do the job myself in a few hours. I did purchase the 6.8 ohm resistors too, but they all checked out find so I didn't replace them. There's a great site online at http://home.earthlink.net/~oleg.filippov/ConvergenceFix.htm that shows you the ropes, just not for this exact set. Once I did a multipoint reconvergence, the HD looks like new! This is at least a $600 service call from what I can gather, and if you're handy you can fix it yourself.

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 )

Ok I got this all up and running. There is a wealth of info out there. All you need is to replace the convergence ICs I replaced mine with stk392-180s as the run cooler and can handle more voltage without blowing. Make sure to use very good thermal compound as it helps quite a bit with the coolring. There are also a few resistors you need to replace. You can find out all about this is you just google stk392-120 replacement. Google is ur friends ; )
Words to the wise be careful with your solder job.

OK, friends. Time to fix it !!. Replace two Ic's Stk 392-110, and get in service menu settings , and adjust point by point. After replaced stk IC's, check if any resistor look brown or born, if yes, replaced it with 6.8 Ohms. If you have questions? [email protected] . Good Luck !!

I also relpaced the 2 ic's for convergence and I can now adjust blue but red still will not adjust horizontally. Any ideas?

Hi, You are to change TWO IC'S for Convergence (Vertical & Horizontal) with IC (PHILIPS) 932212344682. Please have a try! Regards, dsr,india
