Hi Michael,

Thanks for using FixYa. The issue seems to be with poor or loose connections of the IC you replaced. Please check and verify all the connections. I am assuming that sound on your TV is working and you are unable to view any picture on the TV screen.

Make sure that the focus lead is connected firmly (a wire going towards the focus block, in the front of TV set). Please be very careful while checking this as it contains a very high voltage of charge on it (between 10-30 KV). If this wire is fine then please check if you can hear any crispy or crackling sound from the inside of TV set. If yes then it's due to loose connections on the flyback transformer. Please do accept the solution if the issue is resolved or post a comment for further assistance.


Thanks
Rylee

Picture looks dark


I have same model. First set went out of convergence, and I was able to adjust it. A few days later I had same problem and fixed it again. Then I was no longer able to adjust it. I watched TV the way it was. The picture got darker.Then I was watching TV, and there was a flash from the middle of the picture, and TV powered itself off. I unplugged TV and plugged it in 30 seconds later. I powered TV on, and red LED on front panel blinked a few times, and stopped. TV powered itself off.

From what I learned, the LAMP has to be replaced, and so do the convergence chips and convergence resistors. The TV shop charges around $300 and up just for the convergence chips. The TV is selling on craigs list for $150 to $200 in good working condition.

You have to decide if the repairs are worth your while. Probably not in mmost cases.

I'm getting an overlapping of two colors on the screen.


Hi,
It is common problem with rear projection tv and 3D type picture problem occurs due to failure of convergence output ICs, replacement of convergence output ICs will fix the issue and tv will again show correct converge picture as before.
Let me know tv model number written on back of tv if you want to fix tv by yourself as it needs soldering parts in circuit board expertise and if you feel uncomfortable working in tv circuit boards than local tv repairman will do this job for you.
Thanks.

Convergence chips replaced, tv powers on and no picture


You have to replace the chip with the same kind, or at least crossed referenced, but still exactly the same but diffrent manufacturer.

My JVC model number AV-56WP30 has a flashing convergence screen



Your TV most likely has a Convergence Chip Failure but I have not seen that symptom before.

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.

Bent picture


The convergence circuits straighten out the edges of the picture, putting the 3 colors exactly where they should be for the picture to look normal. There are usually 2 large IC's that handle the 6 convergence channels and if one of them burns out then one of the colors bends dramatically. If the power supply for the convergence circuits stops working, then all 3 colors bend in, the colors do not line up with each other and the image looks almost 3D, and the adjustments in the convergence menu will have no effect. I would bet that is the case with your set - the convergence power supply has quit working. If you do not have experience troubleshooting power supplies and realigning convergence circuits in projection TV's then allow a qualified tech to handle it for you.
