My Philips 33FD9944/01S is now working having changed several electrolytic capacitors in the power supply. The television only as a VGA input and works well when connected to my computer. It is normally connected to a Philip FTR9964/12S receiver unit. If I connect a television to either External 1 or External 2 SCART and push the power button the following happens:
The power LED is red for an instant, the relay on the power supply energises. The power LED turns orange. After about 2 seconds the picture from the analogue tuner appears but without sound. The picture remains for about 6 seconds. The power LED turns green, almost immediately the relay de-energises and the power LED starts flashing.
I’ve checked all the electrolytic capacitors in the power supply in-situ with a Peak Atlas ESR meter and all appear to be satisfactory. I’ve also bridged each voltage output from the power supply in turn with a large capacitor. This made no difference. I’ve also tried a large capacitor across the input to the 3.3 volt regulator (7009) and a 47 mfd capacitor across its output, again with no change.
Please can anyone help?
I have managed to download the manual for the 33FD9944/01S but have been unable to find a free download for the FTR9964/12S receiver unit.
