Magnavox 60 Replaced the chip for shrinking and now I have an inward bow at the top and bottom of the screen.

Yes, and also check all low value resistors in convergence circuit.

The curving is caused by bad digital convergencr chips (2) located on large signal board. They need replaced along with blown pico fuses and the convergence resistors. Chips are huge compared to a regular IC. 2" x 1.5" and they will be bolted on fairly large heatsinks. Cloudy picture is most likely the coolant needs replaced in the picture tubes. This needs to be done approximately every 5 years.

This convergence out ICs failure symptoms in TV and you need to replace two convergence out ICs in convergence out section / board in TV
if you are not familiar with TV repair then call qualified Tv tech to fix it.

Your TV most likely has one or more possible problems.

Problem #1: Convergence Chip Failure ( common problem )

Here are some of the most common symptoms and example photos of a convergence problem

• 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.

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 replaced. This is a common problem.

Solution #1

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.

Solution #2


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.

You have a convervence problem. You will need to replace both convergene chips and possibly the resistors. You can get more information and a repair kit with instructions from www.TvRepairKits.com 

If the screen is bouncing...expanding/shrinking you need to get a repair kit from www.TvRepairKits.com

If your screen looks 3d in color, has a stationary bow, or if you can't adjust one or more colors from the "convergence" menu you need to buy a convergence repair kit. You can get one from the same site listed above. 

Hope this Helps, 

Recently had same issue and after EXTENSIVE SEARCHING found all three ICs and replaced them. TV works perfectly, also, replaced convergence ICs at same time. The one 16-pin IC for the regulation ckt. is $49.95 the other 16-pin IC is $19.95 and the 8-pin opto is about $10. This price is for a minimum qty. and must have a business for quote.

Check the fuses 1007 & 1405. If they are blown in will cause an Arc.  

Note: If the screen shrinks/expands you may need a chip kit from www.repairkits.com

im not too sure if those are compatable chips.... if they are then at least you would have to service mode converge the set. something a tech would need to do.
