CTG-100
|
Does not light | Solve pinos do flyback | ||
| PANASONIC |
CT-9022
|
Does not light | Q803 and d810 leaking | ||
| PANASONIC |
CT-9012
|
Power supply does not regulate | Q803 and d810 shorted | ||
| PANASONIC |
G-9
|
The trekking was not there, so there was crosstalk, very intense! | Change the power supply capacitors, the biggest ones there, are generally gray or green... pure old work! | ||
| PANASONIC |
NV G46
|
When a power supply doesn't work because the processor doesn't send the power-on - and when the relay doesn't even arm!! | The relay circuit always has several transistors, generally they are depolarized (without resistors or capacitors connecting their electrodes), therefore closing a short in them, especially in the first one, the relay should arm without the signal from the micro! - be careful when doing this, carefully examine the diagram - they must be depolarized! otherwise, babau... | ||

NV G-46
|
Burning power supply zener (20v) | Change the low capacitance capacitors - 1, 4.7 to 10 micros... otherwise the zener will burn again! | ||
| PANASONIC |
20C6
|
Volume stops increasing before halfway through the scale and the function mode does not work. | I changed the memory (eprom) and it worked normally again. | ||
| PANASONIC |
GV 850
|
Inoperative with humming at the power supply. | It is generally an electrolytic at the power supply with a value of 800uf (very difficult to find). So, put a 1000uf one, and this thing will work properly (without fear of being happy)!!!!! | ||

TC20C2
|
Retrace lines, screen with excessive brightness, screen control on the flay-back cannot darken the screen, and when you try to darken it using this setting, the screen is completely blurred with green. channel indicator characters showing image folding (inverted) along with them. | Capacitor c519 - 4,7uf/450v aberto (seco) | ||
| PANASONIC |
TC 29 V 50B
|
With sound and without image. | Friend, check if there is a transistor without a heatsink on this TV, if so, and it is the cause of this defect. | ||
| PANASONIC |
TC20A10
|
Doesn't work | 24 volt zener connected to the photo-coupler...in the diagram it is right below the power supply circuit...! | ||
| PANASONIC |
TC20A10
|
It doesn't work! | 30v zener diode in the power supply shorted - it is connected together with the photocoupler. | ||
