Blue Color GUN ( I want a buy one ??!!! )

Hi,

Firstly, I have to tell you that my English is not my first language, so excuse me if you have difficulty to understand me.

I live in Montreal, Quebec, Canada.
I have a problem with my projection tv: I have the sound but not the image. When the power is on, at the back of the tv the color guns are red and green and there is a small orange light(LED), but the blue one doesn’t light up. It seems like some clear oily liquid have flew under the blue color gun. I think that the blue color gun has to be change, but I don’t know where to purchase one and how much it could cost. I think I would be able to do it myself, but I need to know if it would need an adjustment after.

Do you know where I can find a color gun? Can I purchase one by internet?

I hope that you’ll be able to help me.

Thank you.

The blue CRT is leaking. This can be repaired by replacing the seal and installing new coolant. The coolant is corrosive and will cause solder deterioration but this is all fixable. I will post a link where you can get the servcie manual for your set which is a PTV840 Chassis. The site sells the service manual which they email to you right after purchase, and they provide free tech support that will help you each step of the way to repair your set, They also will have the new seals coolant and etc that you will need .Here is the link your manual is on page 2 of the phillips /magnavox catagory tittled PTV835-PTV855. Here is the Link. http://servicemanuals.vstore.ca/

Check this site for info on how work on this CRTs. The process of repairing a leaky CRT is not difficult but time consuming and yes you will need to make adjustments after changing or removing the CRT.
You might have to change the circuit board assembly that is connected to the blue color CRT, or you can use rubbing alcohol and a soft hog hair brush to clean it.
Good Luck.

I have a Sony KDS-R60XBR1 projector tv and the blue color seems to be fade out. Is this possibly the light bulb problem?


Yes, either the blue gun is on its way out or there is a problem with the video driver electronics for the blue gun.

Have gone from a good picture to green and blue picture.what happened?


Hi:
If you are connecting the unit by componet cables (RED,GREEN<BLUE) check the cables first to make sure all are connected. If you find they are ok then your red tube may not be lighting up. If you are using a cable box try connectioning the set direct to the cable outlet on your wall. You could also be missing red drive signal to the CRT, in which case service is needed.

I have a Mitsubishi WS 55908 and is has lost its ability to show the color green. What could be the problem?


Hi jazz836,
You're unit has three color gun inside, the red/blue/green gun, since you haven't a green color, green gun is dead. This is caused by faulty resistor, tube, transistor, bad solder joints. If you have necessary tools and test instrument look first for bad solder joints in the neck board, re-solder all cold/dry joints, unplug then re-insert all cable connected. Test the parts in that board and also the tube.
If you can't do the job yourself I would advice you to look for a technician to isolate the problem.
Hope I helped you.
Have a nice day!
Thanks for using Fixya.

No Red color at all. The convergence feature does not work either. Lots of green and blue RCA Model D52W59


Red color gun has failed, which will make the picture over saturated with the other two colors(blue,green) the bad news is the three color guns need to be replace in a set(all at the same time) because if you only replace the red it will over saturate the older blue, green guns then your picture will be mostly red.Unfortunently in most cases it's not worth the investment, better off to purchase a new tv. Good luck !

Blue gun out of focus


There is a manual focus adjustment above and between the red and green gun, located in the front of the TV behind the panel; It is a small black box about 3X3" . This has all three adjustments .

The color is screwed up


The projection TV has 3 color guns that focus to produce a single image. The 3 colors are red, green and blue. It sounds like the blue gun went out. You should be able to remove the back panel of the TV. If doing so, use caution as there is a mirror attached to the back panel. Once removed, you can confirm that the gun is not working. The fix, unfortunately is neither easy nor inexpensive. The problem could be simply a poor connection to the circuit board up to needing the replacement of a new light or perhaps a new gun. Unfortunately, there is no magic button to press and nothing you are doing wrong. This is a very nice TV and it may be worth getting an estimate to repair it. Or, perhaps this is a good excuse to go out and get a new 50" plasma! Hope this helps. If you can think of anything else I should know, please comment.
