Panasonic Repair Guide: Common Issues and Fixes
| Brand | Model | Fault | Detailed Problem | Solution | By |
|---|---|---|---|---|---|
| PANASONIC | SA-AKX600 | Bluetooth connects and loses connection and most of the time it cannot connect | Software update | Software found on the panasonic .com website, on the Brazilian website tsound is no | Renato01abr |
| PANASONIC | TC-L32E5BG | Lower LED current | Change resistor from 20k to 56k connected to pin 15 dp bd9287. so it went from 194ma to 112ma | sérgio | |
| PANASONIC | TC-L42U30B | Sometimes it turns on, and turns off completely out of nowsound, sometimes tsound is no sign of life. | Overprotection circuit being activated erroneously | Zener d7207 on the run, the voltage to activate the protection on the cathode must exceed 6.8v (zener voltage), but feeding with an external power supply, caused the base of the transistor that is connected to the anode of the diode to trigger with 5 volts. | Davi.sls |
| PANASONIC | TC-L42U30B | Normal turns on 3 to 5 minutes... power supply switching... heating up the ic803 a lot | Dz804 de 18volts na base do q817 | I replaced the ic803 and it stopped heating up and switching the power supply (dz804 leaky zener) | Alextecnico |
| PANASONIC | TC-L32B6B | TV turns on and off after a while, red LED flashes once | Pin 7 of the ci u101 inverter board must have 4.8v and it was having 1.7v, note that the LEDs were not defective as they were replaced and the defect still persisted. | Ci defective pin 7 killing the voltage! ci replace | Play back |
| PANASONIC | TH-42PV70LB | After it heats up, the image flashes and becomes saturated, a symptom similar to a defect in the LVDS on LCD TVs. | 8 pin 4d10s smd photocoupler, pc705 position on ysus board | Replacement. | electronicssupplyparts - Gramado/RS |
| PANASONIC | TC-L42U30B | Dead, nothing turns on, not even stand-by | Several leaky diodes. no voltage. only 5v. | Given the various problems, the best solution was to replace the power supply. | SilvioSantosCTV |
| PANASONIC | SA-AKX880 | Doesn't start. When you press power the cooler moves and stops. | Diode shorted on main - d2107 shorted next to ic2101. put an sb320 in place | Alessandro Barcelos | |
| PANASONIC | TC-29KL04 | Turning itself off in less than 2 minutes | I noticed that the strw got very hot and went into protection, causing the power supply to stop, leaving the capacitor charged. I checked the entire power supply and when I removed the cooper, the ferrite was missing a piece at the bottom. | I removed the ferrite from another scrap transformer and repaired hers, the strw reduced the temperature and the TV no longer turned off. | Eliel Magno |

| PANASONIC | TC-L32U30B KM11 | TV activates protection and the standby LED flashes 1x indicating a backlight failure. | Bad pfc capacitor c7212 120uf x 450v, not allowing the power supply to double the 400v | Capacitor replaced | rafaelmoraes99 |
| PANASONIC | TC-L39EM6B | Does not turn on or turn on stand-by | No vcc on ic 7201. defect in capacitor c7206 4.7mf/25v (changed measuring 220Ω). | Moura1 | |
| PANASONIC | TC-L39EM6B | Does not turn on or turn on stand-by | No vcc on ic 7201. defect in capacitor c7206 4.7mf/25v (changed measuring 220Ω). | Moura1 | |
| PANASONIC | TC-L32E5B | LED flashes 8 times | Shorted capacitor smd current filter that goes to the screen, note: tsound are 8 smd capacitors almost under the processor heatsink, remove the 8 capacitors and measure one by one, when detected, leave without the shorted capacitor, it is not necessary, it is necessary make an alternative 13 volt power supply circuit and connect this voltage to these capacitors, one side of which is connected to ground, the other side is necessary to connect this 13 volt power supply, it's easy and it's 100% just make the adaptation | reginaldo moronte,eletronica junior caldas novas | |
| PANASONIC | 32FS600B | Burning leds | LED voltage is very high, around 71v. Tsound are 21 LEDs with a nominal voltage of 63v. | Reduce the LED voltage. remove r7820 and r7821 2r2. the voltage drops from 71 to 64v. | Katutto |
| PANASONIC | TC32A400 | Period, | Mute transistor | Removing q2012 and q2013 is under the board, under the stby keyboard connector. | valdir Macajuba |
| PANASONIC | TC - 20A04 | LED does not turn on, blinking or going into protection | To find out the problem just close the jamp j606 with the jamp j511 and the TV turns on and shows the problem | Resolver | Mauro Mascarenha Tel. (88) 981422821 |
| PANASONIC | TC-55AS700B BT 4LA000193 | Standby stays green for half an hour it goes to red without flashing and even in green tsound is no image | No resolution, mainboard or tcon | Wiliam Martins | |
| PANASONIC | TC-21FX30L | Normal video, low and hoarse audio despite the volume at maximum. | Resistor 257 4.7k open, change it and run for the hug. | Replace resitor 257: 4,7k. | Samuel Infortec |
| PANASONIC | SA AKX74 | Turn on and off f61 | Tda 8950j | Replace entire 8950j | Raimundo |
