My TV has a problem with the red convergence and I cannot adjust ,so it looks green & blue. 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.

Re: Philips HD 60 No red convergence
They are the STK 392-120's ic's on the big heat sink , depending on the numbers in there they may have been replaced with the upgrade or are original , also this could be the cause of a resistor on the chips connection lines (6.8 ohm) , or even a bad solder connection , testing of these should be done before getting the ic's and heat sink compound or solder wick and solder for the job

If the screen is a bright red its indicating an issue with the CRTs could be the red has shorted or the coolant in the blue and green is needing replacement which makes the red Dominate. Looking into the blue and green lenses will verify if its a coolant isssue or not. The convergence issue is most likley failed convergence ICs and the associated 6.8 ohm resistors need replacment.
Projection TV sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the video to look normal. When its out of alignment the video will look 3D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the TV menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired. This is a very common failure on these projection sets and a fairly simple DIY fix. All projection sets including Samsung, RCA, Sony, Philip Magnavox, Panasonic, Pioneer, Akai, GE, JVC, Toshiba, and others at some point will have the same problem.
Common Symptoms include.... •Screen looks 3D •Colors don't line up •One or more colors can't be adjusted when using the convergence menu. •Screen is bowed or warped. •TV shuts off after powering on. Power light will blink. TV may also make a chirping noise.

Ur tv convergence are dead.Must know how to solders?Must repalced 2 STK convergence ICS,and some or all it resistors.Tries websites Tv repair World.com,Tvrepairkits.com to buy a convergence kit to rerpair the tv ur self.The shop will cost u $300-350 for parts and labors.
bad convergence would cause show to look as if it was supposed to be a 3-d movie, if a bulb was going out then people would look purple blue -green,or some other off color, so likely the green bulb is going out from the color of the people you described.
If the colors look 3D or if you can't adjust the blue or red convergence the convergence chips and resistors should be replaced. You can get a repair kit and photo instuction guide for this exact model from www.TvRepairKits.com. Hope this helps
Look for the STKICs mounted on 2 big heatsinks.
I would suggest to replace both of them once you have the TV taken apart.
I think the part markings are STK392-040.
Let me know if you need further assistance.
Jennifer, adjusting it won`t fix it, the convergence IC`s have failed, major job to get them out and unless you have tv tech skills with soldering equipment and volt meter you`ll have to call a tech for this one , sorry to be the bearer of bad news, BMW Rider
Each color (red,green & blue) has an amplifier IC (STK-).
When there is a convergence issue,the first step is change both
IC's for reliability. Then check for open fuses devices,usually
pico fuses.Then re-check convergence alignment.......T.
