PANASONIC	TC20RM10L	Horizontal shaking and losing width	Changed resistor r502		genilson
TV PANASONIC	29KL25	This TV arrived at the workshop with normal sound but with a horizontal scratch	Checking the circuit I found cap c 563 330k 250v as I didn't find the same value I associated 4 of 100k	And defect resolved.	BF.COLATINO
PANASONIC	TV20A10	When turned on, the protection is activated. There is no sound and no image.	Diode d402 shorted at the vertical output.		Rubens
TV PANASONIC	14RM15L	This TV was completely stopped and when I opened it and turned it on, I noticed that the r-850 resistor was getting very hot, causing the q-850 to short out, but when I replaced it, everything remained the same, not even the std-by LED lit up.	All vertical voltages are present except pin 5 which has 0v and should have 28v and pin 6 which has 15v and according to the service manual it should have 29v.	Solved, it was the micro	BF.COLATINO
TV PANASONIC	TC20C20	This TV has no color, I checked capacitors near the do-it-all, resistors and everything, and it didn't solve it	Solved, it was the tda4665.		BF.COLATNO
TV PANASONIC	14RM151	I received this TV when it was stopped, and when I turned it on I noticed that the r-850 resistor was getting very hot.	The cause was the transistor q-850 shorted, I replaced this tr and even so the device still stopped, I noticed that in the lamp in series the device showed consumption and I found the zener d-883 shorted, after replacing the device the LED turned on std-by and it started to work on and off and with the vertical closed, I tested the entire vertical circuit and even replaced the vertical output but the defect persisted..	Resolved, it was the micro.	BF.COLATNO

TV PANASONIC	29KL04.	Q753 shorted from emitter to collector. r768 open, 10r 2w.	Defect in correcting the cushion effect. pin cushion circuit. (solved)		BF.COLATINO
TV PANASONIC	TC 20C7	Side lane	The defect was in two electrolytics that are next to the power supply's chooper transformer. values 47mf/16volts		BF.COLATINO
PANASONIC	TC1410	Does not turn on, in the c823 it measures short	D817 shorted		Bruske
PANASONIC	21FX32L	White screen with lines	Broken print on rgb +b line		luiz gonzaga da silva
TV PANASONIC	29KL04	Doesn't start	Horizontal output shorted. When replacing it with another one, it heated up too quickly to the point of burning your finger if left standing on top of it. Checking a little more, I found d 556 with a leak.	Just replaced it and stopped testing and everything was fine.	BF.COLATINO
TV PANASONIC	14 TC14C4	White lines at the top of the screen	I changed the cp px of the 100/35 volt vertical TDA.		BF.COLATINO
PANASONIC	14R12	Turning off	The TV turns on but passes for a few minutes and turns off, the protection circuit comes into action, turning off the TV.	Capacitor c 519 of 333 mf 160 volts sem carga.	BF.COLATINO
PANASONIC	TC29A11 BR2	Turns off a few seconds after power on	X-ray acting	In this case the defect was in the vertical ci, it activated the x-ray protection, pin 36 of IC 601. This ci (vertical) was replaced and the TV started working normally again	dias
PANASONIC	SA-AK78	F61	There is cold solder on all relays. if it's normal, change the stk-470-050		aureliopr
PANASONIC	TC-14C7	Vertical closes after some time of operation	Resolder the ic401 pins, including the heatsink pins		MARCELO FOUREAUX
PANASONIC	TC 29A8	Volume at maximum, can't lower it even with the control	D 2312 as leakage (6.8v zener)		CABEÇÃO NATAL
PANASONIC	SA-MP11	Mains input fuse blown due to lightning, when changing the fuse it blows again.	Audio output short ic501		This email address is being protected from spambots. You need JavaScript enabled to view it.
