If you see something leaking from the blue tube it is probably coolant. You will need to find the leak and repair it and fill it with the proper amount and type of coolant. Projection TVs with CRTs have to have coolant covering the face of the CRT or they will overheat. Sometimes they can develope a leak. You will need to unplug the unit and remove the rear lower cover. Looking at the blue CRT from the top you should see 4 screws holding the lense on to the crt. Do not remove any other screws or you will change the mechanical focus. Remove the lense and look for the leak. If it can be fixed use good epoxy to seal it. Order a bottle of CRT coolant from http://www.mcmelectronics.com . There should be a filling port on the top of the crt. Fill the chamber to the required level, close, reassemble and you should be back in buisness. If the leak cannot be fixed you would have to replace the crt. I have a tip for that at http://www.fixya.com/support/r4573850-change_crt_in_projection_tv which explains how to do this.
You have to take front projection screen off of tv. When you have taken screen off, turn on tv and observe light coming from the three crts. Look into the face of each crt and you will notice some contamination inside face of one of the crts. Most crts are sealed, so youll have to replace the burnt crt causing spot on picture.
The CRT will need to have new Coolant and new seals installed, and any circuit boards that were dripped on will need a very detailed cleaning to remove any residule as it can ruin the circuit board traces and solder connections
Hi jkclay841 i live new york and have a RCA REAR PROJECTION TV 61" MODEL # P61960 CHASSIS NUMBER PTK195Y06T
IT POWERS ON BUT IT'S OUT OF ALIGNMENT ON ALL COLORS AND MISSING THE CLOTH THAT COVERS THE SPEAKERS HAVE THE REMOTE SCREEN IS IN GREAT CONDITION ALSO HAVE SOME NEW CRT COOLANT RUBER SEALS ,AND THREE NEW LENCES THAT I WAS GOIN TO REPLACE BUT CHANGED MY MIND PLUS NO TIME.
HERE IS MY NUMBER 347- 847 -3348 IM JOSE
The CRTs in modern TVs do not hold a charge because the HV circuit shunts it to ground whenever you power down the TV. You can clean the lens of the CRTs but you can't change the coolant or should you even try. You'll notice that its sealed from the factory. If you suspect a problem with the coolant or that it has dried up or leaked out, you must replace that CRT.
this is a crt type tv- no lamps just crt's if it was moved recently then a seal could have been damaged on the crt cuasing coolant to leak down the neck getting into the socket. this will cause trouble for sure also could have a crack in the crt. look for a sticky liquid in the bottom of the unit.
sometime the crt's can ark and rip out a video output chip on the crt socket check it out.
not common but not unheard of.cheers
No xtended warranty .......common problem bad seal(s) allow
leakage from CRT(s) onto PCB (s)........CRT replacement needed and PCB repair.....check out MO/YR made on sticker on back of set .................!...................T.
Sounds like your Blue CRT is leaking coolant.It will affect the hue for sure and it will also destroy your circuit boards as it is corrosive. Clean any coolant that has spilled onto your Chassis before it causes corrosion. You can buy coolant to replace this, however you will need new seals. This is a proceedure you may be able to handle if you are dilligent and pay attention to details. Replacement coolant can be purchased at the following Link http://www.matelectronics.com/ or this link http://electronix.com/
The seal will probaly have to be orderd through RCA, I am not sure if the links mentioned carry the seals or not you might give them a call to inquire. If I can be of any addittional help let me know.
Yes and that stuff is poisionous. So be careful, not to get on hands, if do clean really good, it's antifreeze like you put in a car. It's called CRT coolant, and it keeps the bulbs cool in your set. Yes it's repairable, If you get it on the circuit board it will damage your tv. You must clean completely if dropped on PCB. You can purchase at places like MCMelectronics, bluestar-online, tritronics etc.
While leaking it must be a bad seal need replacing or screw loose.
