Hello... I'm a troubleshooting trainer for in a contact center in Florida. I'm hoping to get some help with a television that we are having issues with.
I've been told that there is an issue with contaminated coolant in one of the picture tubes, specifically, the blue one. This was confirmed when I looked at the tube and say the spotted haxy look on it.
In reference to the technician...it was suggested that a qualifed tech would need to look at the issue. I'm learning by experience in my new postion, so any help would really be appreciated. I need to know if it's just the picture tubes that would need to be ordered or if there is another solution for this. The TV in question belongs to a customer that purchased it in '01. I have all the info for the TV if/when you need it.

Re: Question about a Phillips 50
All thats required is for the coolant to be changed you dont have to change the Tube as a new tube wont include the lens coolant assembly or coolant. So just change the coolant in the green and blue red doesnt get affected and you will be fine.

According to " Consumer Affairs. com", the problems with seris of Phillips plasmas are innumberable. And they all start with the flashing red light, from 3 - 7 times. Baased on the information you gave, there is something wrong with the TV itself, not your perifrials. I would contact Phillips/ Magnavox to see if they will pay for an authorized sevice center visit, or even ship you a part to solve the problem.
I would suggest first that you have a technician come over and troubleshoot your problem to determine which stage of the TV is malfunctioning. Then If you want you can have the technician repair the problem or swap out the board. This believe it or not is the cheaper option. I know that today a lot of people think that board swapping is the best thing, but in reality it's just a time consuming object lesson in futility, because you never know if you have fixed the problem or just bought more time. In any event try the option above, and if that is not to your liking try to send the boards to http://www.ptscorp.com/. Contact them to discuss your options on sending them the boards.
This might be an indication of defective CRTs (Cathode Ray Tubes). I would first check to see if the Green and Blue CRTs were functioning or have other issues such as coolant leakage (do visual inspection). Anything other then this will require you to contact a qualified TV repair Technician to troubleshoot the problem. I would suggest for starters that the technician perform a test on the CRTs with a CRT tester, This is the best way to do this it will cut to the possible cause right away, if the CRTs can be rejuvenated, at least you will have about two to three more years of use out of the TV before the CRTs are completely gone. However if the tubes are not the problem then the technician will have to troubleshoot the circuitry the connects to the CRTs.
Your set doesnt have a bulb. Its a crt projection unit. Is the set completely dead? If so troubleshooting the power supply is needed. If the audio works but no picture, then the deflection/HV circuits will need troubleshooting. Let me know if I can assist you further.
