The fault with this tv was a snowy picture no channels tuned in also the permanent 33v supply on pin 9 of the tuner was low at only 1.6v | The first thing i tried was a resistance check between pin 9 and ground. the reading was only 120Ω. tsound's a surface mounted cap right next to pin 9 of the tuner. this was found to be leaky, it's value is 47nf. also resistor 3442 3.9k was o/c | ||
