The coolant is clear ethylene glycol and can be purchased at any electronic parts store or online. Look up "projection tube coolant". Usually you can get by with only changing the liquid in the blue and green tubes, and be prepared for a messy job. You'll need a small bucket to drain the tubes into and make sure to pour a straight stream to avoid liquid getting into lenses. Just take your time and this repair is very simple to accomplish. Also, I use a marker all the way down the side of the tube and on mounting frame to assure that I don't get it turned around when reinstalling. Make sure you clean inside of coolant chamber thoroughly. Good luck, Russmann.

Hi,
The coolant inside each of the tubes need to be flushed cleaned and refilled.Over the years of the TV's use, the coolant gets cloudy from heat. usually this kind of service can range from $350-$650+ dollars.

Convergence bowed


Hi

the coming out is glycol oil (coolant). If still under warranty or if you have no electronic repair experience you should take the set back to the shop or to a repair person. Some of the solutions described below can be dangerous, TV's are very hazardous to service. Even when plugged out, TV's can store very high voltages.

Looks like a picture tube problem.
Try to reduce the contrast, maybe it will be better.

Look into the three tubes while the TV is running, and observe the
picture quality of the three. If the red and green are crisper and clearer, and the blue's all hazy from bacteria growing in the coolant, then the fluid needs to be replaced. The CRTs of the colors that seem hazy need to be removed from the light box to be
serviced. The coolant needs to be drained, the CRT assemblies
disassembled and totally scrubbed clean and refilled, then reinstalled and converged. If the coolant is
clear, it can be a weak CRT.

Also the convergence STK ships might need to be replaced, and the soldering checked.

Good luck

Changing coolant


I would recomend the service manual as they explain how to change the coolant, then re-align everything once your done. I would change the blue and green. Red never seems to have an issue with the coolant . I believe it has to do with the color spectrum. You wont need any special tools. The service manual will explain the safe way to discharge the CRTs as they can store energy till they are properly discharged. I will psot a link where you can get the service manual emailed to you if you would like. I work for that site and the service manuals are great, cheap prices and they offer free tech assistance. I am one of their techs. Let me know if you would like the link.
