53UWX10B Red giving problems

The red projector on my tv is not just giving me a strange convergence, but it is giving me thin red lines accross the top of the screen in an up-side down semi circle. The further out from the center of the screen you look the red convergence gets worse and the picture stretches out.

Good Day,

Welcome to the world of having a convergence circuit problem. There two things you can do; get it repaired by a Factory Authorized Service Center or repair it your self. Purchase KIT 10 from B&D Enterprises, 1-800-458-6053. The kit has everything you will need except soldering equipment and experience. Good Luck, big IRISH.

Red screen(rear projector tv)


Most likely bad convergence amplifiers. They are soldered in components.They can become intimentent and the lines come and go, usually red or blue.

Red lines running through tv


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.

Progressively worse red "ghosting" when showing films....


This could be either a connection problem internally or a problem with the red filter convergence. This is not a project to be attempted by an inexperienced person. The convergence adjustments should only be attempted with the proper setup and equipment. If you can solder, carefully open up the unit and look for poor solder joints and resolder them. You can also reseat all of the connectors and cables. If neither of the above ersolve the problem, take it in for service.

Convergence problem


We need a better description of what you mean by shadowing. However I am assuming: 1. You mean it ''bleeds'' off to the right when you have something with a hard red/blue drive. 2. When you turn the contrast and color down a bit it gets better. unfortunatly I cannot tell you how to fix convergence, but I can think of some other possibilities. In this case the red/blue emmision of the crt is dying off and going into saturation when driven hard. To fix, replace with a new picture tube/crt. In some cases you can get a little more life out of that tube (with a watchable picture) by having the screen, focus, cathode bias, and drives slightly readjusted. It will take someone with experience in doing these adjustments on a weak tube to get it looking as good as possible. Given the construction of the cathodes (guns) in that crt, only a very low level crt reactivate should be tried on it. The hard rejuv most crt testers give is highly likley to completely destroy the cathode on that crt.
