| Brand | Model | Fault | Detailed Problem | Solution | By |
|---|---|---|---|---|---|
| PANASONIC | MX-D830 | Turns on, with all normal voltages, but tsound is no sound | Memory locked due to some error in the device | Reset memory mic4 25l1006. temporarily short circuit pin 8 of the 3.3v to gnd while turning on the device. When the device starts up completely, remove the short circuit. | Jump Eletrônica |
| PANASONIC | TH-42PV80LB GPH11DA | TV does not turn on, red LED flashes once. | Cold solder on the bga microprocessors on the main board a. | Resoldering of bga microprocessors position ic8001 and ic9901 | Rafael do Carmo |
| PANASONIC | TC-14RM12L | When turned on, it works for a few seconds and turns off, with the LED blinking. | Defective protection circuit. | After measuring all the voltages and they were all ok, the solution was to turn off the protection circuit (remove r1106) and the device worked normally. | Francisco Oliveira |
| PANASONIC | TC-L32B6B | With normal sound without image backlight on | T-com board | Janilson JD ELETRONICA CAETITÉ-BA | |
| PANASONIC | SA-AKX50 | Turns on in a few seconds turns off | The cause was a high power supply that caused the short in the audio output, I found the ic5799 - mip2f2 leaking in the power supply and the transistor q5720 - ktd863y, I tested it, it was leaking a lot, I replaced it with new ones, the power supply came back with normal tension and in the audio output I replaced the ic5400 and ic5000 - tda8950j both are shorted, I also found swollen and exhausted electrolytic capacitors c5510,c5511,c5512,c5513 - 220uf 50v and c5440,c5040 - 22uf 100v | I replaced all these components and the Panasonic sound was ok. | Eletrônica Dolby |
| PANASONIC | 29KL03 | No contrast | Was replaced r557,res.95k3 open. | José delta line | |
| PANASONIC | TC20A12 | Works - frame reduced to top with flickering image | Ci 451 | Replace ci 451-vertical-an5539=la7840 | EMERSON RIBEIRO |
| PANASONIC | SA-AK220 | When you press power, f61 appears on the display and then turns off. | Sound output (rsn35h2b) and cold soldering on almost the entire amplifier board. | Changing the output and resoldering the amplifier board. | Liani Belles |
| PANASONIC | L24X5B | Blinking LED doesn't turn on | C1110 c1114 orange capacitors replace without measuring | Mega Center | |
| PANASONIC | TV14A12 | Vertical position would suddenly stretch a little and the TV would turn off and blink on standby | C519 open (it is close to the fly-back on the +b line) | naldo | |
| PANASONIC | TC-20A9 TNP4G076 | Blurry image when switching on. After a few minutes on, the image was normal. | It was leaking high voltage from the focus wire at the flyback output. the focus wire was loose from inside the flyback and was oxidized. | Flyback replace. | Rafael Silveira |
| PANASONIC | TC14A8 | Does not turn on with normal power supply | Faulty ic 101 | Replaced and got file | leilson lagoa de roça pb |
| PANASONIC | TC20A10 | Vertical opening only 4cm in the center of the screen | Resistor r425 27k aberto | Replace of the same | mateuspagnan |
| PANASONIC | TC20A8 | No contrast | R564 100k | Replace and go to the crowd | Mega Center |
| PANASONIC | 29KL 04 | Burning q753 | Tvc had output h and q 753 burned out, after the change the tvc kept burning q753 | Replacing the d 556 rh 3g diode - problem solved | zapeletronica |
| PANASONIC | TC-29KL05 | The relay would hit and go into protection mode, it wouldn't turn on | D556 shorted | I replaced d556, q753, r768, c757, c563, r520 and r521 the defect was resolved thanks to this forum I will share it with you | This email address is being protected from spambots.

| PANASONIC | TC-32X30B | Green LED flashes several times and then the red LED flashes 3 times and does not turn on | I released the cable that takes the signal to the display on the side of the main board, the TV turned on the screen. I reconnected the cable to the main board again and the defect returned. Even so, I left it connected and disconnected it from the display side and the defect persisted. I even thought the defect was in the cable. l | I cleaned the side of the cable connected to the main board using an eraser like we do on computer memories and applied contact cleaner to the main board connection, and the TV started working normally again. | jfr |
| PANASONIC | TC-20C5 | Almost completely closed vertical | R455 open | jpsky | |
| PANASONIC | TC20C5 | No sound and no image with horizontal output transistor shorted q501 | When replacing the horizontal output transistor q501 burns out immediately. | In my case I had to replace q501(2sd1632), c511(peak capacitor) 8200pf and also the flyback(tlf15564) simultaneously as they were all burnt out. It is good to check all capacitors and diodes of the horizontal output and also the 180v line and finally check the +b 140volts. | Otacilio |
