Red streaks across my screen of my tv

Tried everything to +- to even them out but it didn't work. How do I remove the red streaks ? I have a 65 inch Mitsubishi Medallion HD1080. It just happened one day all of a sudden. Could it be the red lamp?

    Red swoosh across screen. I used the remote to go into the menu to adjust the red convergence +- but it helps a little but red streaks are still there.

    its kind of hard to tell but it looks like your convergence chip (the red one) is shorted. usually about $250-$400 if you take to a tv repair shop.

My JVC projection television AV-48WP30 has green and red streaks at the top with one long blue streak going across the screen. I tried everything that I could to fix it by the tv and remote and it still...


Your TV most likely has one of two 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 around images.

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

JVC 65 inch AV-65WP55 tv, the color red is failing


The tube is old. You need to contact a service center. He may try to boost it from inside. If it doesn't work, then need a new tube.

Mitsubishi tv problem


im assumiong you checked the tint in the menu options. if not go check it. other wise it sounds like you have a weak tube, or you do not know how to adjust the screen brightness. this is how i adjust the brightness (you dont need to touch the focus). turn the red up until your whole screen is tinted red, then do the same with the blue and the green. then go through each one and turn down just a little till your pic darkens a little. good luck

The lines you saw, i;m sure they are the ones called retrace lines but know the failure could be located on the red CRT board. Most likely the video amplifier is defective and not necessarily the CRT.
What is the model number of your TV?

Yes the red tube is shorted. I will post a link to the site where I work as they have an entire AV48WP30 with a bad tuner they are selling parts off of including the Tubes. they also provide free info on how to switch out the tubes as a unit which is a fairly easy job. Heres the link.
