Convergerence will not get rid off my ''red ghosting'' problem

I recently had a little event 11-16-08 for my 6 yr old and all his friends. They were jumping and banging aroung the living room. After they left, acouple of hours later, A red ghost image appears on my screen. I called the support line for Panasonic and we walked through the convergence steps. NOT EVEN CLOSE TO HELPING THIS PROBLEM OUT!!! I need help and have no idea whats going on, I am an electrician, but have no experience in TV repair.. Did the continuous thumping of the kids knock something outta wack? Is the reflection of the red lense outta place? Any help would be greatly appreciated..

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.

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.

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.

It is likely that there are poor solder connections at the convergence ICs. The extra vibration might have been enough to completely break the connections. If you can solder, you can fix this yourself. Look for large black ICs attached to a heat sink . They should be marked STKxxx. If you can solder, try resoldering the pins first. If that fails to resolve the problem, replace the ICs.

Please note that there are high voltages that can be dangerous inside the set even with the set unplugged.

Keep me posted,
Dan

My hitachi Model recent quit working . No picture or sound. Red light does not come on. Sounds as if power supply went out but really not sure how to check. please advise. Thanks


So you can go to walmart buy a 50" TV for about $500. A power board for your old TV gonna run about $150 and the repairman prolly charge another $150 so why try fix the old one? TVs are too cheap to buy now so no reason fix an old ghost screen.

How can I get rid of the coloured lines?


you should do the following tasks:
Press the left side of the TV with your hand, if the colors got disappeared, fortunately the flat cable inside the TV causes the problem. But
If the problem still insists, the panel board inside the TV got corrupted and you must change it with a new one.

Stuff coming out of AC vents


Thats normal for an older car..
It is debris & foam insalation that is around the ducking..
Worse thing that might happen from that is you loose a little insalation,, and make a clean car a little messy..

GB4308 Ghosting


The cost I don't know, but this can be fixed. There are generally 3 lamps in projection T.V.'s, Red, Green, and Blue. They have to be aligned for the TV to project a clear picture. A credible TV repairman should be able to fix it. Depending on if it's new enough to be under warranty they may cover it as well. Really the only reason to get rid of it is if you want to get a new TV anyway. Depends on the cost of having the lamps aligned.

Sounds like your describing convergence ICs. They cost about 10.00 each and you will need to replace both of them. And possibly the resistors that power them total cost under 30 dollars if you do he soldering yourself. Hope this helps.
