Panasonic Repair Guide: Common Issues and Fixes
| Brand | Model | Fault | Detailed Problem | Solution | By |
|---|---|---|---|---|---|
| PANASONIC | TC-42AS610B | Just green LED and no image | Burned out LEDs (check the buses) | Remove the screen carefully, remove the screen support and remove the films in order, turn on the TV and see which bars the LEDs blink, the ones that blink the LEDs are good, the ones that don't blink the LEDs are defective | Gbrito |
| PANASONIC | NN-ST652W | Sets the time by pressing start, turns off and resets the display. on the 10sec key it works | Two apparently normal 4.7x450v capacitors. | I put two 4.7x400v ones and they returned to normal. | XANDARE |
| PANASONIC | TC-40CS600B | Red LED just blinks | Short smd capacitor on the remote receiver board. | Jorge | |
| PANASONIC | TC-20G11 | Doesn't start | Capacitor c811 100uf kept voltage at 170v at most b I changed it it dropped to normal 130 it didn't turn on the diode 602 was open | C811 d602 | Antonio Neto |
| PANASONIC | TC-29KL05 | Black bars on the left side of the TV | Causes diode d558 to short | naelson silva gravata pe | |
| PANASONIC | VARIAS | Access hotel mode and initial settings. input volume and others | Hold down volume minus on the TV and 3x input button on the control | Paial.eletros | |
| PANASONIC | TC L32 | Test rgb | Hold down volume minus on the TV and 3x submenu button on the control | It alternates green red blue white and black | Paial.eletros |
| PANASONIC | TC L32 | Access service mode | Hold down volume minus on the TV and 3x red button on the control | The rest is intuitive | Paial.eletros |
| PANASONIC | TC20A12 | Turning off | Replace r558 (22k) | elj | |
| PANASONIC | TC-L47ET5B | It has normal sound, blacklight comes on, but tsound is no image. | On the t-com board tsound are four capacitors in a row at the tip of the board, one of them was shorted, cap. 161 killing one of the voltages on the board ok, resolved. | Galileu Rocha | |
| PANASONIC | TC-L32C30B | When it was cold, it would turn on normally when it got hot, it would turn off and the green LED would flash, and before it turned off, if you unplugged it and turned it on again, it wouldn't turn on immediately. | I thought it was a power supply, I even changed the board because the symptoms were from a power supply but it was BGA | I did reballing, changing the balls that are underneath the processor | Edivan Eletrônica |
| PANASONIC | SA-AK250 | The device turns on normally, but when it plays audio, it goes into protection (f61). | *cooler * | In this case, maintenance was carried out on the ventilation cooler, it was locked! | Eletrônica Barros |
| PANASONIC | TC-L42G11B | STBY LED flashing 9 times | Power supply board 24v oscillator | As I didn't have the integrated circuit, the power supply board was completely replaced. | ALEXANDRE SOUZA |
| PANASONIC | TC-L42E5BG TPNH0993 | LEDs turn on dark screen no image only sound | Capacitor c140 on tcon board shorted | ALVES.TEC ELETRONICA | |
| PANASONIC | TC-14RM10 | TV stays on and off continuously; 140v power supply drops to 120v when the TV shows the image and the TV turns off and on again | Defect in the primary power supply, the cause was d831 | naelson silva gravata pe | |
| PANASONIC | TC-L32C30B | Totally inoperative, the 5v does not reach pin 1 of the connector that goes to the main board. | Resistor r7314 | Replace r7314. in this case the resistor had replaced its value to a lower value, even though this is difficult to happen. However, sometimes the glue under the resistor that conducts and replaces its value. | Company Tronics |

However, sometimes the glue under the resistor that conducts and replaces its value. | Company Tronics |
| PANASONIC | TC-14A12 | When plugged into the socket it starts then it has 140v at but b when it turns off 70 at but b | It was resistor r631 for 560k | NANDO ELETRONICO | |
| PANASONIC | TC-20RM12L | Does not turn on stand-by LED off voltage +b 207v | Replaced the regulator ic801 str-w6554a equivalent str-w7854 the power supply returned to normal but it did not start. | I searched the components I found two open diodes d867 and d876 in4148 replaced the voltages will return to normal the TV will work again | João eletrônico |
| PANASONIC | SA-AKX220 | Sometimes it disables the power supply as soon as you press the power key or after a few minutes | Arming power supply protection - voltage on pin 8 of con2 connector rises | Flake nose zener d1013 (15v) and d1003 (7v5) - | RUBERVAL SBC |
