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 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
PANASONIC TC-L42E30B
Turns on with a dark picture on one side and turns off Defect in LED buses and inverter board replace the LED bars, in my case tsound was also a problem with the inverter, I solved it by re-soldering all the resistors on the inverter board ITALOPACZ DOORNEL
PANASONIC SA-AKX710
The device turns on, lighting only the colored LEDs and then turns off. power supply, SMD diode (with flashing) connected to pin 15 of IC1501 Diode replacement. NOTE: I didn't find the specifications for this diode, I put a board cutout on it and it worked. But based on the characteristics of wsound it is positioned in the circuit and the diode impedance test, I came to the conclusion that it is a fast diode, with a higher voltage and is not a schottky. If anyone discovers a specific diode that is correct, please repost a tip informing us to help everyone. Gênios Eletrônica SJ

PANASONIC TC-L42ET5B
No picture C194 capacitor shorted from TCON board, 10microfarads SMD from board Marcelo
PANASONIC TC-L42E5BG
standby LED flashes 3 times. c207 on the t-con board shorted and fuse pa7402 on the power supply board. replace the shorted c207 and fuse pa7402 on the power supply board, I inserted a 10mfx50 volt electrolytic eletronica cachoeira
PANASONIC TC-32D20
Backlight flashes and goes off, standby light flashes red 4x Burnt out LED bars. You can deactivate the burnouts if you have a good bus and it still works normally. Replacing complete new buses in 2024 (200 reais per piece). It doesn't last more than 5 months even with minimum backlight and little use. I don't recommend...
