SHARP	C 1453 OU 2053	When turning off the screen, it remains on without an image. Like the screen was washed, that is, it did not turn off completely	Change q706 of the power circuit		pedrinho tela quente
SHARP	20R12	Plug it into the socket, the TV turns on directly if you turn it off using the control or key, it won't turn on anymore, just remove it from the socket and	Photo coupler and the capacitor in the 1000uf 35v power supply	Replace	EletroClaudio Aguas Belas
SHARP	C-20RS03	Does not turn on power supply ok 115v ok 5v ok but does not turn on.	R676 10k aberto	Replace it and run for the hug.	toinho eletron
SHARP	C1632 OU C1432	When turned on, it makes a beeping sound and the power supply is turned off	Flyback	Check the horizontal output collector line, disconnect pin 3 or fly if the voltage returns, replace it	joaomvjr
SHARP	C1632 OU C1432	High secondary voltage burns 2rm diode	R706 (10r) non-primary, open.	Replace	joaomvjr
SHARP	C2999G	Stop	Replacement of zener diodes d2001 with leakage, d2081 open.	Replace zener diodes d2001,d2081. both 5v6	LIDER ELETRONICA
SHARP	C-20R12	Vertical closed, just a line in the middle of the tube.	Diode d661 shorted and r656 open.	Replace them	toinho eletron
SHARP	C2188	Vertical folding at the bottom	1000mf/35v cap, low capacitance and good esr.	Replace do cap c506 1000mf/35v	LIDER ELETRONICA
SHARP	C1467	Don't care! secondary zero! I don't have the strength to leave	1.8m r704 open	Replacement	orlando lott
SHARP	C-2017	Doesn't start singing like cricket cri, cri, cri etc...	Capacitor c721 ceramic 103k 1kv shorted	Replace it and ok	TONIO DA ELETRONICA
SHARP	C2040B	Very low sound	I changed the output and capacity of one thousand x 25 volts, it didn't help		beto
SHARP	TVC :SHARP C-21 ST 54.	Protection activates 2 seconds after turning on the device	In this case the short was vertical; check the vertical stage, starting with the shorted or leaking diode, ceramic capacitor in parallel with the diode, check 100 mf x 35v filter, resistor r/504,390r/ open	Lastly, changing the vertical output .tda 3653-bq >will solve the problem.

SHARP	C-2040B	Vertical closed just a strip in the middle	Broken r645 and r606 solder c507 exhausted	Resoldering of r645 and r606, changing the c507, which made it work again	fbio
SHARP	C-14T51	When it turns on it makes noise at the power supply	Stk 73907 of poor quality		Eletronica Bianca Ipirá BA
SHARP	C2999	Dark screen with no image. normal sound.	R 882 120k open	Replace res.	DEBIQUE
SHARP	C-29ST58	TV didn't oscillate, all good power supplys, well this TV appeared in the electronics already messed up, in the oscillator circuit I found a toasted resistor r 609=5k6 I changed it and the q602 = tr oscillator and nothing. Then I found it in the vertical output r505=33r toasted and a cap:de100uffor 63v with low capacity and the ic501=tda8350 shorted, I changed it and nda.it was then that in a partnership with my friend stefanio we discovered that it didn't have the 8volts of q754, these 8 volts are what starts the oscillator circuit of the pin 40 of ic200=tda 8375.	Cause in q754 which has 8v it only had 3v, with the help of my friend stefanio we discovered that the cause of everything was the q760=bc858 a smd tr (pnp) that was shorted near the micro.	The q760=bc858 tr smd was replaced, the TV worked and the sμFfering ended uuuuμFa...!	Armando de Olímpia:Eletronica evolusom.
