V-chip is a set of features not a physical chip that can be removed. It is activated by firmware and shows up as menus in the receiver's setup screens.
Dont set it, and it will not activate... or see your manufacturers user manual on steps to re-set.

    The "V-chip" (which, as others have said, isn't really a physical component, as such, as much as it is some extra code programmed into the microcontroller which runs the TV tuner section) does not allow outside agencies to "censor" your TV without your knowledge or permission. It's sole purpose is to let parents control what kinds of programs their kids are allowed to watch unattended, if they care to do so. All it does is allow a parent to program the set not to display programs tagged with certain ratings or content flags unless the parent(s) are there to override the settings with their PIN code. If you don't have any kids, or if you do have kids but don't wish to prevent them from watching certain kinds of shows (who knows, maybe you're one of those lassaiz-faire kind of parents who doesn't see anything wrong with their eight-year-old watching gangsta-rap videos), all you have to do is not activate that function in the TV set's setup menu.

Philips 60 convergence problem

When you take off the back of the TV, you should see a fairly large circuit board with two black chips that are standing vertical. They should each say STK392-XXX (where the X's are typically 100, 110, etc.). The "convergence chips," as they are called, can cost you anywhere from 15-30 dollars depending on where you buy them. You can either go to a TV repair shop and have them order the parts for you, which means there would be a middle man, or you could find some online. has a number of kits available to make the job easier. You just plug in the brand, type, and model number of the TV and you can look at the various kits they offer. Last time I checked it was roughly $70.00 for two chips, soldering guide, online support, and some other stuff.

Another option would be to simply type the chips code (STK3392-XXX) into a search engine (google, yahoo, etc.) and then see if you can buy the chips alone. This would msot definitley be a cheaper option.

Once you have ordered the convergence chips, you are going to have to remove the circuit board/wires and anything attached to the circuit board. Once you have the circuit board out, you are going to need to flip the circuit board over and remove the solder using a soldering gun and some "wick" that will soak up the solder. You will have to do this for both chips, flip the circuit board over, remove the clamps, then remove the chips. Next, I would insert the chip, clamp it in, flip the circuit board back over and begin soldering the pins individually. Do this for both chips.

Chances are, you are also going to have to repalce some resistors as well. To do this you will need a multimeter that measures ohms and a chart telling you how to read resistors. One can be found on under the hints/tips section.

All in all, it should only take about an hour with fairly good soldering skills. So you will need a screwdriver with a "star" shaped head, possibly a philips head screw driver, and a steady set of hands to remove the circuit board. Then you will need some desoldering wick, a soldering iron (I would use a 15 watt iron), some small-diameter flux-core solder (rosin), and some patience. There a PLENTY of youtube videos that go through the repair step-by-step.

It's not as bad as it may seem after reading this article. Soldering is not difficult, however, when working with circuity it can be somewhat easy to screw something up. That being said...a little confidence and a lot of patience should get you through it. Good Luck!!!

The red light on the front flashes and tv wont turn on

1) Convergence chips are shorted....One quick test is to desolder and remove both STK392 chips....then power the set on. If the tubes light up the chips were shorted. You can get new ones from

2) Another possible problem is a bad HVG - AKA the flyback.

Try the convergence chip test first. Note: On some Philips sets you can just unplug cable "1516" instead of removing the chips.

For instructions on how to find/remove cable 1516 visit the website listed above and click on their tips page. On that page click on the "Magnavox DPTV3xxx Checks" link.

Green Swooping Band on Top Of Screen JVC- 56WP74

Your convergence chip, or chips are gone. Easy to replace on this TV via front access panel. Remove the front speaker panel open up the access port and remove the front board. Get the IC's online and solder them in and replace, Make sure to check all of the resistors as they also blow and replace as needed. Make sure to use a good thermal paste like MX2 as this is the baser problem as to why these fail (you will see what I mean when you remove the chips)

My TV too got a "bow" at the bottom of the screen. Seem like many suggested replacing this STK chip and also it's $10/each so I went ahead buy 2 to replace the 2 in my TV.

Below is a pic of the inside of my projector TV with the STK-392-110 circled in green and as you can see it is easy to ID due to the HUGE heat sink that it mount on to help dissipate the heat. (sorry for the small size since Fixya limit the file size to 150KB)


I unplugged the TV for more then 3 days and that seem to discharged most of the components.

So here are the steps I take to do the fixing.
1) Before I even order the chip I open it up to verify the part number and it was STK-392-110. Did many research try to find as much as I could about this chip and make sure I order the correct one... so I made the order. While waiting for the product, the TV had been unplug ever since.

2) Well, in order to even get to the inside I need to dismount the back panel. So it had stayed open ever since, of cause out of reach of children.

3) The components arrived and I prepared:
- soldering iron
- solder
- heat sink compound (used mainly to fill in a good gap for CPU heatsink inside computer)
- and solder sucker (the sucker later I found to be useless).
- Flashlights
- Screw driver
- Plier.

O, and my brother offer his help which I found to be very useful. My 2 hands weren't enough to do this work.

4) Removed the 4 screws which I marked with the yellow arrow inside the pic.

5) I didn't want to remove any cable afraid that it might create other problems but had to remove about 3 cables to make it easier to lift and move the board around a little while fixing.

6) Removed 4 screws that mount the chip to it's heat sink using a very short screwdriver. Very little space to work with.

7) It was extremely hard to remove the old chip with the board still cabled to the TV. Many times I was tempted to disconnect all the cables. What prevent me from doing so was I couldn't think of a good way to document all the cables that I disconnect and there are just too many (IMO). I did take many pics just in case.
Anyway, what I did might not be the best way but it worked. I tip the chip back and forth to weaken the pins to a point that it broke. It took forever but it did work. After the chip broke off that I can desolder and remove each pin with the plier. Again with the little space to work with that made me want to remove it from the TV. The pins holes were still very messy and full of solder. My brother came up with a way to clean the hole using stripped wires. When the stranded strip wires touch the liquid solder, it help suck the solder out of the hole. I'm sure there are better ways to clean the holes.

8) We had a little hard time putting the new chip in b/c a few pins bended a little and not align with the holes on board. And when added the compound to the chip, it made it even harder since now the chip need to stay away from the heat sink or else it'll stick to the heatsink. Finally we got the new chip in the holes on the PCB with the compound and all, so it just a matter of screwing the chip onto this heat sink.
9) Turn on TV and pic is 99% perfect again. Why not 100% U might ask.. b/c I saw a tiny out of align colors on the left of the screen. Not very noticeable but I can see it when I pay close attention.

Cost for the two chips were $20 included shipping. Hey, it's a lot cheaper then buy new TV and only 2 chips trashed instead of the entire TV. Anyway, I think I knew which chip went bad. Because one chip had hardly any of the compound. This compound help the transfer of heat to the heat sink.

Hope this help someone.
