Question about Televison & Video
Check SMPS power supply. DC voltages. First check the power supply
bridge/ diodes. Then check DC votage should be 70% rating of the
capacitor voltage. If the capacitor is dry it will show low voltage.
But the diodes should be OK. Check the high wattage resistors
connected in the power supply. There will be a resistor in the
ac input also. Beyond this check all +DC voltages.
