Panasonic Repair Guide: Common Issues and Fixes
| Brand | Model | Fault | Detailed Problem | Solution | By |
|---|---|---|---|---|---|
| PANASONIC | TC-32F400B | connect, then turn off, without picture and sound | LEDs Burned | Normal tensions in the food, go to check the LEDs as possible and had a burnt when replacing TV worked normal. | WellingtonLCC |
| PANASONIC | NN-ST27JWRUN | Do not turn on the display if the membrane flat fits the display lights | In my case it was the membrane shortly replaced the membrane and run to hug | jorge assistencia tecnica cotia sp | |
| PANASONIC | TC-L39B6B | Without picture, with blacklight access, looking like a symptom of defective display | IC5421 on the back of the burnt plate | replace of IC5421 or plate | LEANDRO VOSS |
| PANASONIC | TC-P50G11B | Tsound are times when it gets the green LED and the light screen but it doesn't work, and tsound are times the red LED flashes 7x or 6x | Very dirt/dust inside | Make a complete cleaning on all flat cable connections | Wsmartcell |
| PANASONIC | TC32D400BE | The TV turns on then to flashing the green LED simultaneously | It was sensor from TV | It was a larger capacitor that has on the sensor plate, I removed the capacitor from the place and the TV called normally, more for the service to be complete put another in place | Toinho antenas |
| PANASONIC | TC32D400BE | TV turns on with green LED flashing simultaneously | It was a defective TV sensor on the larger capacitor | I removed the capacitor and the TV went back to work, but put in place after | Toinho antenas |
| PANASONIC | TC-39AS600B | TV calls and shuts down 3x | Advanced LED bar, lit only half of the LEDs, the other half was lit, but with weak luminoside. | LED bar replacement | MISAEL |
| PANASONIC | SA-AKX700 | CD doesn't work | This sound arrived at my workshop with the following defect, I press the Open and Close key, it doesn't open, I opened the device, repaired it, the motors weren't working, I checked IC SA1466, it was shorted, I replaced it, resolved the CD, it was ok | Carlos | Carlos |
| PANASONIC | SA-AKX700 | Usb does not work A and B | I opened the device, analyzed the board, tsound were 2 shorted ICs, 5 SMD pins IC9002 and IC9003 code VBYQ = TPS2051C I bought Panasonic resolved USB A B worked perfectly | Andrei Electronics | Andrei |
| PANASONIC | L32U30B | TURN ON BACKLIGHT AND STANDBY BLINKING NON-STOP | CAPACITOR C7212 -120UF 450V | LOGANKLEITON | |
| PANASONIC | SC UA7 | F61 when turning on the device | It doesn't turn on, it only stays on the display f61 | Claudemir Dias pestana | |
| PANASONIC | SA-AKX700 | Sound does not turn on | TPS54240 and diode Code 36M9B I put the SS36 diode in its place | Resolved | Andre |
| PANASONIC | SA-AKX700 | Reduce power supply voltage at 40V output | To reduce the voltage of the Panasonic sound power supply so it doesn't burn out TPS54240 Regulator, First place a 4k7 resistor pin 5v connected to pin 12 PCONT of the power supply, I just soldered it, I turned on the test power supply it was giving 38.4 V output, I reduced it near IC1701 pin 1 to 4 resistors in series 182 = 1K8 / 0 ohm /333=33k /0 ohm, I just replace 1k8 for 15k and 33k 10k, I did the procedure and turned on the power supply, voltage dropped to 32.1V. | It doesn't go beyond the TPS54240, sound working normally | Andre |
| PANASONIC | TC-L32C30B | turning off | replace resistors R7830 and R7829 from 470r to 1K | oskarala | |
| PANASONIC | TC-L42U30B | It turns on, the picture appears and goes off, it does this 3 times and then the standby LED flashes once at each interval | Activating protection. In the power supply board connector that goes to the main one, on the power supply side, remove the wire from pin 12 and ground | Eletrônica Barbato | |
| PANASONIC | TC-L32E10B | Pulse power supply and screen | R814 | R 814 replaced on the power supply board | Marcelo |
| PANASONIC | TC-L32E10B | Pulsing screen and font | R814 replaced from power supply board | Marcelo | |
| PANASONIC | TC-40D400B | ON AND OFF (RED LED FLASHES) | BACKLIGHT MOSFETS GETTING VERY HOT, ONE OF THE BARS WAS AT 60V, THE OTHERS AT 48V. THEY SHOULD BE 48V. replace THE LED BARS RETURNED TO 48V AT THE OUTPUT WHICH WAS 60V AND STOPPED THE MOSFETS TO BE WARNED. | REPLACING THE LED BARS | LEO DA MEGA |
| PANASONIC | TC-32FS500B | No picture | Burnt out LED (1 LED) | After replace the LED bars, reduce the current on the IC drive's ISET pin. With the original circuit, if the voltage is above 60V, replace the ISET resistor, put double the value, then check the current/voltage if it is within acceptable standards. | Cesar762 |
| PANASONIC | 49ES630B | TV turns on normally with sound, no picture, but LEDs on | T-CON Board Defect, shorted board | replace capacitors c135 and c136 on the t-com board | Eletrônica EMB |
