PANASONIC	TC 37LX80LB	Does not turn on, red LED flashes twice	Inverter plate	Inverter plate	Eletrônica NA
PANASONIC	TC-14RM10L	TV sometimes turns on, sometimes it doesn't. When it doesn't turn on, the secondary power supply remains at zero.	Changed power supply regulator. strw 6754" "be careful" this ci, tsound are many fakes.	Replace power supply regulator.	MARCONES DE ARARIPINA-PE
PANASONIC	TC14A12	It started turning off after being on for a while, and then stopped turning on altogether.	D511 ma4108, zener diode (x-ray prot circuit) and 10.8v 1/2 w open.	Replaced the diode and it worked normally again, it is close to the fly back on the back of the board.	José Dias
PANASONIC	TC-14RM10L	In AV it works normally in RF it didn't tune at all	Varicap	Replace it with another and run to another	Antonio Carlos (Eletrônica Renascer)
PANASONIC	TC-14RM10L	Image shaking after a few hours on	D810 ars150 or b0eakt000018 leaks after it heats up.	Replace d810. In my case, I put a byw95c in its place. recommendation from a friend, Zezinho, of Araripina telesom electronics.	MARCONES DE ARARIPINA PE.
PANASONIC	TC-L42E6B	Give up the sheep	Shorted capacitor close to the cable that comes from the power supply (one of the four that are together) you have to test one by one to know which one is defective.		Bruno Nicácio
PANASONIC	TC-L32C30B	Turns on and off then the green LED flashes several times and then turns red	The connectors p5 p6 p7 and p8 of the lamps with poor contact	Eliminate the connectors and solder directly to the board	ELETRÔNICA POPULAR
PANASONIC	TC-14A10	Turns on normal image is shaking both on the channels and on the av	Tufted capacitor underneath c853 - 220uf 50v I replaced it and it stopped shaking and the image was normal	Defect resolved	Andre
