Replace the green projection gun

I am attempting to fix my fathers RCA Projection TV and ordered a kine-green projection gun part #256714. I need to know how to put the coolant into the gun and how much to put in. Also should I check the red and blue guns for the correct amount of coolant??? How would this be done? Thank you for your help...

Re: replace the green projection gun

This is a very difficult repair to try and make. You not only have to replace the tube, but when the tube is replaced, you will have to perform convergence adjustments, which are very difficult. The green tube is the worst to try and replace because the red and blue tubes are converged onto the green which means now you will have no reference point to start from. It's not just a matter of dropping the new tube in and turning the tv on, also if you but the tube as an RCA original, it will come already filled with coolant.

Re: replace the green projection gun

I have almost the same problem, but it was with the blue CRT tube. The coolant leaked onto the underlying PCB and caused short-circuits and sparking or arking. I purchased an exact replacement PCB for the CRT, but I suspected most of its coolant had gone, so I need to re-fill the coolant for the blue CRT to stay cool.

I have an RCA Scenium HD DLP 50" TV Rear

What is the Model Number that is printed on back of TV?
You say TV is DLP ,but you are posting Model# HD52W59 that is for Projection that has 3 Tubes Red/Green/Blue Tubes.
If TV is DLP then problem will be the Color Wheel
If it is Projection then it has a coil on the deflection board that either needs to be replaced or
resolder ciol and take a Glue gun and glue over the top of coil. Coil LL037 on the right handside of the FBT flyback transfomer.

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 !

Thin vertical lines

Those lines are called retrace lines. They are there all the time on projection TVs but you should be able to see them. When you do see them, that's an indication that the kine screen settings are too high or the supply voltage to the kine driver circuit is low or missing. There is a small, black control unit located behind the speaker grill assy in the front of the TV that has 2 sets of 3 controls. A red, blue, and green focus and screen controls. See if you can make the lines dissappear by turning the screen controls counterclockwise. If you can't you'll need to have service come out to troubleshoot it.
