SHARP	C1417	Normal alloy activates protection after a certain time	Replace zener diode 4.7 v- dz615		nonato
SHARP	C 2038	Reduced frame, sometimes it turns off and goes into protection	Head. 7n5/ 1k6 polyester	Replace of the same	eletronicaapolo
SHARP	C2057	It was stopped o + b was ok 115v + it didn't fluctuate for a long time I looked for the defect I decided to change the memory and to my surprise it started working again, but what a poor joy it didn't last long I saw that the image after 5 minutes the screen starts to blink until it turn it off and now to start with a lot of research on the ci tda 8374a on pin 22bean-cur input terminal for stage abl tsound is a capacitor c230 that goes to ground 220p so I decided to put another 10n capacitor in parallel and then tsound was a file, then this TV gave a beating on me is the victory of those who persevere	Change memory and place in parallel a 10n cap on the c230 cap		fernando timbauba .PE.

SHARP	C2026H	Tv doesn't work	Zd708 120v zener diode shorted (note: this diode shorts out because c712=220uf for 35v loses its capacity and the power supply keeps varying; tsoundfore, whenever you find zd708 shorted, also replace c712, otherwise the diode will short out again.. .OK.).	Trick zd 708 and 712, looks great.	Armando da Eletrônica só Tv.
SHARP	C1453	Protection acting	Q 706		c@rlinhoselectro
SHARP	2057	When turning on the TV, the voltage transistor driver Kai is 6 volts 8 volts	Solution to change the memory in my case was the memory could also be the computer	It was replaced and the memory remained	fernando ferreira
SHARP	C14R12	Doesn't start	Modified horizontal transformer drive	Trafo drive was replaced and the defect resolved	thiago
SHARP	C-2013	TV doesn't turn on and keeps beeping	Horizontal output (q602) shorted. The horizontal output was replaced, the TV turned on, but the horizontal output burned out again within a few seconds. wide capacitor (c616) of 8.2nf had its value changed to around 1nf and burning the horizontal output. The problem was solved by changing the horizontal output and the wide capacitor.	Replace of c616 and q602	sergiofne(at)gmail.com
SHARP	C-2013	TV doesn't turn on and keeps beeping	Horizontal output (q602) shorted. The horizontal output was replaced, the TV turned on, but the horizontal output burned out again within a few seconds. wide capacitor (c616) of 8.2nf had its value changed to around 1nf and burning the vertical output. The problem was solved by changing the horizontal output and the wide capacitor.		sergiofne(at)gmail.com
SHARP	C20T51	Vertical closed and opened and buzzed loudly on the video card	Tube socket	Replace the tube socket	eletronica shalon
SHARP	C-21ST54	No audio/normal image volume scale on normal screen, audio signal at the output indicating that the output c.i. is good.	Eeprom=l24co4p w/default	It was replaced for a 24c04 from the Atnél brand and it was... ok.	Armando da Eletrônica só Tv.
SHARP	C2017	Complementing "flashing" screen defect.	Cold welds in the power supply region.	Analyzing the defect further, c716 was also found to have a defect in the solder and thus correcting the others in the power supply area. Before these corrections, it was possible to observe that the voltage on the collector of the horizontal output transistor was very reduced and after re-welding it returned to the correct values.	py3ig
SHARP	C2017	"flashing" image.	Screen reduction and resolved.	This device comes with focus and screen for external adjustment and also possible user adjustments.	py3ig
SHARP	C2899	Burning d1556	1.6k capacitor that connects to the tranzistor emitter		isaias s machado
SHARP	70GS61S GA10	Eht surge then stby or stby with no surge	Q709 (+5v reg ic) is defective, output voltage drops to bellow 3v when under load.		AusieNick
SHARP	DV1416	Does not start the power supply	Trans 706 [bf437] resistencia 728 [15k]		digitecni
SHARP	C2899	Horizontal transistor burnout	Changing the 1.6k capacitor that powers the tranzistor emitter	Substituted 1.6k capacitor	isaias s machado
SHARP	20ST58	Stop	R203 de 33r zener de 33v, e cinescopio	Apparently it seemed to be the tda, but when enlarged and reduced the screen the image appeared weak	EDSON
