    I am having the same problem. A blue mirrored image is displayed just above. This is occurring only from the middle on down. Any suggestions? The television is a Toshiba 61H70.

this sounds like a convergence loss... the most likely cause of this is what is known as stk's or convergenc ic(chips) have gone bad.. also it cound be the output resistors. most likely need replaced

Hi olchap

your tv is projection, maby the heat is causing the bulbs to brighten and dim, you should try to keep the room its in fairly cold or try and have the bulbs replaced to ones that are not as strong,

hope that helps a little ^-^

this is a crt type tv- no lamps just crt's if it was moved recently then a seal could have been damaged on the crt cuasing coolant to leak down the neck getting into the socket. this will cause trouble for sure also could have a crack in the crt. look for a sticky liquid in the bottom of the unit.
sometime the crt's can ark and rip out a video output chip on the crt socket check it out.
not common but not unheard of.cheers

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.

My toshiba 57 inch rear projection tv every once in awhile makes a loud pop similar to a spark noise and the screen either goes black or flickers. do you have any suggestions what is causing this??


THis could be one of the CRTs (Color Tubes) is bad or the high voltage is leaking somewhere.
Toshiba projection TVs have history of yoke problems.
My guess is one of the CRTs is arcing inside. This TV has 3 CRTs red, green and blue. Replacing a CRT is not easy or cheap to buy if you can find it. If you like this try calling a TV technician to track down the high voltage arcing. DO NOT TRY TO DO THIS BY YOURSELF.

Best of luck my friend.

Alot of rear projection t.v.'s have a convergence option in the menu on the t.v. There you can set the try to set the colors back how their supposed to. Mine has a cross in the middle of the screen and you just have to try to get all 3 colors to line up. Unfortunately, the actual lens inside mine has to be aligned so it doesnt work. Just something to try though, hope it helps.

Tv color not bright enough and just replaced lamp


Clean the small mirror in front that projects the image onto the rear mirror. The Rear mirror always stays good but the front small mirror gets dusty and the colors and bright levels get affected and appear dim.

50inch toshiba color problem


Projection TV sets are known to have two common problems. The first problem that is common to these sets is convergence failure. When this happens the TV will usually look 3D, Wavy/Distorted, etc. It may also shutdown and blink an error code.

The second common problem with Projection TV sets is dull video, halos around objects, white looking video, or red overpowers the screen. This is commonly caused by the fluid in the lens being clouded overs.
