Panasonic Repair Guide: Common Issues and Fixes
| Brand | Model | Fault | Detailed Problem | Solution | By |
|---|---|---|---|---|---|
| PANASONIC | TC-L42U30B KM11 | TV won't turn on without stand-by | Double diode d806 with leakage. | The diode with minimal leakage but sμFficient to activate the ovp protection circuit. | eletrofepar |
| PANASONIC | TC14RM15 GL1 | Does not turn on LED blinks activates protection raises protection turns on with half screen | See open 2k7 resistor 405 | paulo antena | |
| PANASONIC | TC-40C400B | TV with sound and no image LED bar on | Capacitor (cd13) shorted on the LCD board | Remove the same | iNOVA ELETRONICA |
| PANASONIC | SA-AKX880 | Not calling | The wire of the box is chewed | Renata | |
| PANASONIC | 21FX32L | Constantly turns on and off | Was replaced d1132 zener 5.4v shorted | José delta line | |
| PANASONIC | TC-L42S20B | Red LED flashing 7x | Short circuit on inverter board | Replace switching transistors (fdd8447l) | TVPAULO |
| PANASONIC | TC-21FX30L | Turns on normally after 10 minutes turns off | C818=1/50v e c842=10/50v | ELETRÔNICA CENTER | |
| PANASONIC | TC-32AS600B | TV doesn't turn on, or turns off by itself, or sometimes doesn't turn on and freezes. | Defect in the function keyboard PCI. pci is double sided, and the power button track was shorted to gnd. Loosen all components and test track impedance at x10. | Isolate the track close to the connector and close to the touch switch, and make a jumper with a very thin wire. | rafaelmoraes99 |
| PANASONIC | TC-32AS600B | TV doesn't turn on, or turns off by itself, or sometimes doesn't turn on at all. | SMD touch key on the keyboard has poor functions, causing the TV to have intermittent defects. In my case it was the power key stuck closed, causing the TV to not turn on and remain frozen. | Changing bad touch keys. | rafaelmoraes99 |
| PANASONIC | TC-L42U30B | No image lamps light up | 12v was missing on the tcom | Ceramic smd short main board without position number but next to tcom a15 flat connector | iran alves dos santos |
| PANASONIC | TC-21FX30L MXT | Doesn't start | Standby and turn off | Changing the transistor q850 | ELETRONICA SALES.NATAL RN |
| PANASONIC | TC-P50UT50B | Turns on and then turns off, red LED flashes 12 times | According to the service manual, 12 blinks is a defect in the audio amplifier | Replace IC audio amplifier position IC4900 code BD5452AMUV | shermanflima |
| PANASONIC | TC-40C400B | It would turn on, then the image would flash about 2-3 times, the TV would disarm and the red standby LED would blink once | I thought it was the LED, I replaced the bar, the problem continued, I checked the SMD fet on the power supply near the LED output, tsound was a bad cold solder, I resoldered it and it worked normally again | Lucas | |
| PANASONIC | TC-L32B6B | Turns on the LEDs works and turns off flashes red light | Altered bus with some LEDs burned out or shorted | Replace the LEDs or complete bus | VelkDj |
| PANASONIC | SA-AK36 | 3.3v voltage oscillating between 1 volts is 3.3 volts | Diode d10 on the FR103 power supply board | Replace d10 diode | josé everaldo dos santos ribeiro |
| PANASONIC | TC-L39EL6B | Does not turn on, without stb. | Leaky capacitor on the main board close to IC 8704. | Jadson G Nascimento | |
| PANASONIC | TC-L42ET5B | Turns on BL twice, then goes into protection and the red LED flashes. 1 time | Usually bulbs, but after changing, the defect persisted | Changing protection resistors on one of the LED power channels, against overvoltage, on the inverter PCI, 2 x 684 and 1x 563, a leak would raise this voltage, tsoundfore triggering the protection. | davi.sls |
| PANASONIC | TC-24U400 | Doesn't start | TV doesn't turn on, power supply without 5v | Zener diode with pass d7307--- 7.5volts | oskarala |
| PANASONIC | TC-21FX32L | Blue screen when connecting antenna becomes dark with characters and sound | Rakh D Sakh, Ak | Replace | Eletrônica Mauro Mascarenha - Parazinho Ceara - Tel : (88)981422821 |
| PANASONIC | TC 21FX32L | With sound characters and no image or no contrast | Rakh D Sakh, Ak | Replace | Eletrônica Mauro Mascarenha - Parazinho Ceara - Tel : (88)981422821 |
