Good morning!
My name is Albert. I from Poland. I have problem with my tv Sharp model DV-6303S. First situation: I take out high voltage transformer (screen, focus, hv 1182.5024=HR6475), and connect 60Watt bulb between +153V and collector of 2SD1546. When tv is stand-by, and then, when I press button to switch on, the light is on, on 60Watt bulb. I see light on 60Watt bulb, every thing is ok, and no pictures of course, only characteristic sound-15,625 kHz.
Second situation: I put in that transformer of high voltage. I connect collector of 2SD1546 with returning +153V from transformer of high voltage. Then I switch on the tv. When tv is stand-by everything is ok. This is last situation when tv is working. When I press button to switch on television, I hear horrible sound. Maybe 1 second. The tv destroy 2 transistor-2SD1546, TEA 2261, and fuse 2A. Potentiometer R716 is suspicion. I look at him, and I see that he is breaks. That potentiometer is regulation od TEA 5170. And next, TEA 5170 is regulation TEA 2261 witch regulation 2SD1546, witch safe that fuse 2A.
Please tell me, what is wrong with my television, and tell me please, how many Ohms, of that R716(47k) potentiometer I need to regulation???My English is not good, but I think You understand me.
With kind regards.
