Problem with the Toshiba 50H13 50 in. Rear Projection Television. Green tint


The tubes have aged and the colour balance between the tubes has shifted. You will need to redo it using a black/white test image: first the black (the cutoff point), then the white (the gain) on each tube - always start with the green colour. This is done on the final video amplifier of each tube by adjusting the corresponding semiadjustable resistors.

My picture has broken into colour ghosting (it looks like a 3d picture without the glasses on). I'm guessing that this might be the failure of one of the colour bulbs. The wavey colour bands that I see are...

Projection TV sets have two very common problems. One is convergence ( 3D/Warped video) the other is CRT fluid ( Dull Video). Here are more details and solutions for both. Repair kits with instructions are also avail from www.TvRepairKits.com

Common Problem #1) Convergence has gone out

Projection TV sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the video to look normal. When its out of alignment the video will look 3D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the TV menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired.

This is a very common failure on these projection sets and a fairly simple DIY fix. All projection sets including Samsung, RCA, Sony, Philip Magnavox, Panasonic, Pioneer, Akai, GE, JVC, Toshiba, and others at some point will have the same problem.

Common Symptoms include....


  • 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.
  • TV shuts off after powering on. Power light will blink. TV may also make a chirping noise.
Here are some pics of convergence problems.

Common 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.

When i switch my tv on. I can hera the volume but no picture. Then the tv switches off and restarts until both the volume and picture is working. This could take up to an hour


yes. tv has a circuit which controls current to the red, green, and blue piture tubes. you wont get picture until they are balanced. adjust the screen controls until it comes on faster. it should only take maximum 20 seconds for a picture. gaurantee it will fix it. adjust the screen control

Problem with a colour display on Hisense tv


If your picures are all purple it means that the green colour is missing. TV colour is made up by mixing Red, Green & Blue. Removing Green leaving Red & Blue makes purple. Study the green colour circuit for a fault and confirm that the green gun inside the tube is working.

Panasonic 47 HDTV blue looks green


What you have there is referred to as white balance... The Overall White Balance May Suddenly Change And Become More Red, Green, Or Blue Depending On Which Crt Has Been Affected. During Turn Off A Crt Might Arc, Causing D304 (Red), D331 (Green) D361 (Blue) Damage And Leak Changing Cutoff Levels. Replace Diodes With Panasonic Kit # Txask02gser. Kit Contains 3 Diodes And 3 100k Resistors. Install New Diode And Resistor In Series In Place Of Old Diode. Install Annode In Crt Socket Where The Old Annode Was. Then Connect Resistor To Cathode End, Other End Of Resistor Goes Into Pcb Where The Old Diode Cathode Was.
A job like this in my shop we charge $280.00 dollars plus tax which includes the kit... Also a pickup/delivery fee if we have to go and get the unit...
