pull the light assembly out clean it with a vacuum and some pressurized air spray and place it back in the TV, while it is out check the fans on either the inside or in the removable assembly for damage or other interference in operation...If this doent help dissemble/remove the rear of the enclosure ( 6-10 screws) and clean the insides carefully and then turn the tv on - being careful not to be touching ANYthing and see if you locate the culprit.....

Follow the power cord into the set--it goes almost directly to the ac line fuse inside the set.

what is the problem in convergence?

If you are looking to repair the set for a convergence problem or other which part are you asking about?

Samsung HCM5525W... | Answered on Jun 03, 2012


A few possible reasons--the usual if dead is power supply or set is in protective shut down--means someone has to open, check for voltages in and out of the power supply.

The "its happening more and more" suggests a more sinister possible issue.

This set uses 3 picture tubes and is well known for the coolant in one or more (seen one with all three leaking) leaking the Glycol--as more leaks it gets worse.

If someone opens the set and looks for signs on the wires above the main boards and on the boards below (will be if there seen in first 6 inches or so from front of set--signs of what looks like even a small amount of clear liquid--Glycol has leaked.

DO NOT if you see signs of it touch it---very toxic and more toxic than antifreeze which it is except more concentrated.

It causes all sorts of problems as it dissolves metal leads and parts.

Let me know (you have to look carefully!) if you find this.

This is from another fixya article but its relevant to your 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

  • 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.

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 aroundimages.

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.

If this set is new, a problem like this would be covered by warranty. If it is no longer under warranty, locate the convergence ICs which will be large black ICs attacked to a heatsink. Try resoldering the pins on these ICs first. If that does not resolve the problem, replace the ICs. These should be marked STKxxx.

Keep me posted,
Dan
