I have a 51mp392/h17 tv. I replaced the convergence chips and the resistors. At first, I could not adjust all the color bars. Went back and found a terminal not soldered. Fixed that but when trying again all I got was the popping sound when the tv was powered up and then when it stopped. Did this repeatedly. I checked on this site and others to find possible causes. The picture would not come back on before but now it will come on when I plug it in after being disconnected for a few minutes then goes back off with no popping sound. I have checked the pica fuses and they are good. What can possibly cause this problem.

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
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.

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.
SOURCE: convergence bad
resistor along the convergence are 2Watt size or less. they are easy to find as all of them are in pairs. if you find one is not the same on the other, then replace that resistor. change the 2 convergence IC at the same time. let us know.
