29″ CRT TV Philips Problem Solved!
I have a 29" CRT TV of Philips, PT2452/94S, which had arching problem at the base of the LOT cable that goes to anode of the tube. Since a good LOT as replacement was not available, I decided to patch up the leak. First of all I discharged the anode at CRT end, removed the connector, tied an insulation tape at the puncture, and inserted an insulation sleeve taken from a piece of underground telephone cable, which was a tight fit. Then I slid on a piece of petrol tube that is used in two wheelers, covering the entire cable upto the CRT connector.
Refit the anode cap, switched on and TV started working, but switched off after a few seconds. In service mode, error code was detected as 11 (problem in RGB). Replaced TDA6107 at the CRT PCB. Adjusted the focus and screen control to its optimum. Set worked fine. As a routine measure, I replaced all the 48 Electrolytic capacitors and also some of the high voltage capacitors around LOT. Set now works like a brand new one!
