Question about Projection Televisions

1 Answer

The picture on my 32" philips CRT is green. The set is 4 years old and I assume the tube is faulty. Is there any adjustment I can make or what would be the repair cost of a new tube, including fiting?

Hello father,

Though it is possible that the tube is defective as you pointed out, may I offer an alternative diagnosis? Most CRT type TVs are driven by three (3) transistors located in a squarish PCB at the very rear of the picture tube. Each transistor is responsible to drive the red, blue and green guns of the CRT. If the green drive transistor is defective, the symptom you have described would also be the result. It is even possible that the transistor is not defective but any of its pins/terminals might have developed a cold solder.

Should this be the case, then the repair would be relatively easy (replace or re-solder as required) and comparatively low cost.

Should you venture a DIY, please be reminded of safety procedures/precautions when working with high voltages. Should you be uncomfortable going this route, perhaps your best bet would be to seek the services of a qualified professional.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FixYa.

Sounds like you may have just left one of the wires loose from the red tube. Not likely an issue from the gren tube but you can always cover the top of the lens and let just green shine up. That may help narrow it down also.

Here is more detailed info for you also.....

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.

What you will need to do is replace the coolant and clean the crt. You can get a repair kit from TvRepairKits.com . It includes replacement coolant,step by step instructions, support, etc.

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.

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.

Toshiba 65H14 is all green... Tint doesn't change it..


As TVs age, the rate at which the CRTs begin to decline in terms of light output increases. If you go into the customer menu and adjust the color setting to zero. ( no color) observe the image. Is it good gray scale? Or, is the image still green tinted? If so, its definitely a problem with the CRTs( picture tubes) You may need to just re-adjust the screen settings for the CRTs or it may be more serious, a CRT may be bad. Replacing the CRT is a job for an expert and will cost $500-700.

Bad picture


A 10 year old Rear Projection tv is usually at the end of its life. No such thing as "fluid". Best advice, get a new TV.

Bowing at the bottom of the picture


your convergence ICs need to be changed both of them. You can get replacements at the following and they include free installation instructions with free onkine tech support when you do the repair. heres the link your model should take STK392-110 or STK392-120 which interchange but the 120s are a better chip.

Green Picture.


i suggest to have it check by a qualified service technician. there seems to be a problem with your crt (cathode ray tube). because inside this projection tv are 3 crt guns responsible for color red, green and blue, which only qualified technician can adjust it and replace if it is necessary.
