I received a 55807 that has been in storage for a few years. The unit worked fine the first night, no problems. The next day the unit would not turn on and I found fluid on the I/C board and power board. After reading the threads on this GREAT forum (thanks for all the insightful tips!), all fuses were fine and I replaced the I/C convergence chips and had a tray to catch the drips from the 'blue' CRT that was leaking. I cleaned the coolant off the boards with alcohol and dried them over night. The unit started up fine but there was a black spot in the center of the screen right from the start. I do not have a remote yet, waiting for a replacement to run the convergence service menu The unit ran for 2 days and quit again, this time there was fluid from the other 2 CRTs leaking on all 3 boards. Both pico fuses associated with the I/C circuits were blown. I removed all 3 boards and cleaned them again. I ordered the repair kit that contains OEM Sanyo chips, fuses and resistors. The first chips I purchased were not OEM, just a cheap replacement, at least they were only $7 each. I now pulled all 3 CRT to find/repair the seals and replace the coolant and I notice that directly in the center of all 3 CRT's there is a single black spot on the back surface that would match the spots on the screen. Is this permanent and are the CRT's are toast? If not, what are the problems am I facing to dissassemble the CRT's and repair the fauly seals? From what I have read, you are not to remove the spring loaded screws at all on the housing. Why? I believe the leak is coming from underneath the sheet metal guards. I have also read that the spots may be caused by a high voltage spike on the power board. I do not have the equipment to check the high voltage, just a voltage tester, wiggy and amp meter. They are not rated for the 30k-40k volts. Any suggestions or comments are appreciated.
