Various symptoms, time turns on, no sound, hangs on the philco logo. When it doesn't matter, it's just on Stanbay. time turns on and the dashboard LEDs do not light up | I checked the power supply, the memory | I noticed when I heated the motherboard with the thermal blower the TV turned on normally when it cooled down the TV stopped and the symptoms started as I described. I started heating the capacitors on the motherboard and one capacitor in particular when I heated it the TV worked normally and I removed it to measure 100μF/16v volts it had a low capacitance of 47μF. I replaced it with 100μF/25v and the TV started working normally again. | Adriano Miranda |
