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 32A400B
v320bj7 		League without picture Only with VGL, without VGH and other voltages VAA line showing low reverse conduction (resistance). Leaking CD19 capacitor. Casa do Computador Muriaé
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...
PANASONIC TC-L42U30B
KM11 		The backlight lamps flash and activate protection, the standby LED starts flashing 1x Cold welding on the power supply transformer position T800. rafaelmoraes99
PANASONIC TC-32F400B
Turn on the panel LEDs and tsound is no picture. Short in the v-con resets the 12V replace or remove the smd ceramic capacitor position CP38. Alessandro B. Barcelos
PANASONIC NN ST654WRUN
Style 		When setting the time and starting, the time does not count and after 3 seconds the relays turn off and the display goes out. Start no longer works. L101 coil, 180k RY Coil L101 next to the 4.7mf x 450v capacitors, and the open 180k RY resistor. Digitecnica Eletrônica
PANASONIC TC-37LZ85 TC-37LZ800
LH71 		The TV responds to the initial on command but turns off after a few seconds. Check F1 in T-CON and IC7001 in TNPA4467 AdamRep
PANASONIC TC-40DS600X
Goes into protection. turns on, image appears for a few seconds, error: LED flashes every 3 seconds Problem with the backlight line, the problem is just one LED The problem is in just one LED, however, the BD8289F controller goes into protection A. Carreto
PANASONIC TC-39A400B
V390hj1 		Turn the LEDs on and off Open leds To remove the inverter protection, simply add a 10k resistor from pin 12 to ground. Eletronilo
PANASONIC SA AKX16
Display does not show characters Add a 47k resistor in parallel with capacitor c902 on the display board Sivaldo eletrônica
PANASONIC TC-L32X30B
Standby LED flashes red 1x Test LEDs and inverter 24v power supply In my case it was the defective inverter board. Eletrônica JJ
PANASONIC NNS 62 BH
Turns off after 3 seconds Micro key for the door to which it is connected together with the relay Replace of the same Marcelo
PANASONIC TC-L32C20B
0000 		Turns on LED flashes 15 times and turns off Faulty display screen Old iron lol.... Jhone eletronica
PANASONIC SA-AKX440
Doesn't start. power supplys arm and then disarm D1001 changed Replace diode with 1n4007 or equivalent marcelo lima
