60PP920217F Convergence Problem?

I've read about the convergence problems and what to get to fix them, but I'm curious if that is where I should start. I got the tv from the couple that bought it new, and they had apparently had the convergence fixed on the tv once already. Then, a few weeks later, the tv messed up again. They called the same repair place and the guy said that it was the same issue and quoted them like 400 to replace the board.
I got the tv home and plugged it in and all it does is chirp and the power button lights up red.. Any ideas on where to start? This is my first time in a tv, but I have alot of experience- mechanical and electrical with automotive applications as well as being a senior mechanical engineering student.

    I read some of the other posts about this tv set, so I unplugged cable 1516 and the tv screen lights up for about 5 seconds. Is the tv-kit-011 what I need to fix this issue? I will check the resistors also. What all is included in the kit? Would I be better off just getting the chips and the resistors?

First- On the conv bd. check all the resistors I beleive most of the bias res. are 6.8 ohms, they are usually paired that would mean 3.4 ohms. Any that have changed in value must be replaced, we use 1watt/2%. That set should have lasted a lot longer than two weeks. Probably bad resistors that were not replaced. You will have to replace the STK's again.2- (STK392-120 ? ) Let me know and hope this gets you started.

    That's the +15 and -15 volt source for the IC's. That's why it will start temporarily. That rail also has IC2 bus line on it that monitors the fact everything is ok and of course it is not so it tell Mr Micro to shut down. I don't recommend you buy the board, reason being, if you have never done a complete convergence with the template you'll never make it. It's best for you to try and repair the old one. Let me know..

    The numers are on the IC's, you can try Encompass Parts,,,,MCM Electronics,,,MAT Electronics.

Here is a quick test....

Using your original remote go-to the tv settings then goto the convergence section.

Try to adjust the red and then the blue convergence.



You should be able to move them up, down, left, and right.

If you can't move them in all directions your convergence chips are bad and should be repla60PP920217F Convergence Problem? - 2c07611.pngs a common problem.

You need to replace the convergence chips and convergence resistors. Check the site www.TvRepairKits.com. They have put together a kits for most models. If you don't see a kit for your set send them a quick note and they will put one together for you. Their kits include a photo instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, etc.


Problem #2 CRT Fluid is Cloudy

Projection TV tubes have a liquid coolant that is used to keep them from overheating. After many years the coolant in the blue and green tubes will become cloudy and cause the screen to look dull, red/orange, etc. You may even see halos around images.

Picture of a set that needs the fluid changed.

What you will need to do is replace the coolant and clean the crt. You can get a repair kit from www.TvRepairKits.com that includes replacement coolant, photos. instructions, etc.

Convergence problem please help


You likely did not do all the steps required to fix it. If you bought a complete repair kit from sites such as Tv Repair Ktis go back and ask them for help. If you did not get one of their kits you can still purchase just the convergence repair instructions.

I have a Philips 60"


The set will need a convergence repair kit. Or to turn the red CRT off you can turn the screens down on the red CRT untill it shuts off, But the set will have a very blue or green picture and will not be very good to watch. A convergence repair kit is the best way. You can get the repair kit with instructions from www.tvrepairworld.com

PHILLIPS BIG SCREEN TV IS BUTTERFLIED


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.
