WS-55315 Red Gun Slow to come on

I have a 3 yr old 55315. When I turn it on you can clearly see that the red gun is not on. After about 5-10 minutes, the screen turns completely red for about half a second and then the picture is great. Is there a known problem with the guns?

You could have a bad transistor for the red gun on the neck board or possibly a cracked solder joint on the transistor. The red gun may need to be 'cleaned' by a rejuvination process. The guns can get a buildup on them after time that needs to be burned off to bring it back to life. In some cases, if the coating on the gun is very thin it can be burned completely off during a rejuv. process leaving it totally unusable. It is possible to use a charged capacitor to 'zap' the guns to attempt a rejuv., but it may need more than what a capacitor can give it.

The picture screen is green and red.


It sounds like one of the three color guns has failed and based on the fact that you have red and green that would leave the blue gun as the culprit.

I have a Mitsubishi WS-55315 55-inch tv that suddenly without warning the picture seems to have lost all red color. The picture seems clear but it is mostly green in color. The problem is intermittant...


Hi
Check the componet cables if you are using them for video from the cable box, the red may of came loose.Also you could have intermittent connection the video processor IC or as we techs call it the jungle IC. It is responsible for producing all the small singals used by the set.Tapping with the handle of a screwdriver on the signal board may lead you

The set has a bowed appearance and the 3 colors have seperated. I imagine the bulb(s) are going as it's a old set.


The arching of color can be adjusted on the color gun by slighty turning the screw on the gun Blue, Green, Red. This fixes the arching and or fade-blinking in and out of color. The gun on my 65" sony is inthe front of the set. Removing the front panel grants me access to this. You may have to access it from the back on your model. Looks like a small box with 3 screws ont he front. Hope that helps...

Red convergence problem - Mitsubishi 65


It sounds like your red gun might be close to going, we had the same problem our tv. The red was off and couldnt really be adjusted but the others were alright. We were told that the red gun was nearing the end of its life and it could cost upwards of $1000 to fix, so we just got a new tv. i would suggest having a tv tech come out and look just to make sure, but thats wut it sounds like.
