Make	Model	Symptom	Problem	Solution	By
SHARP	C-1440B	Pulsates but does not oscillate	C666(1u/100volt)	Substituir o c666(1u/100volt)prox ao th	jarbas santos
SHARP	C-2030-A	Horizontal band, vertical circuit defect dark screen at top and bottom.	Solder the +b track with leakage between diode d503 and resistor r514.		João SF.
SHARP	1453/2053	Turns on and then turns off and or does not turn on with noise from the oscillator	Check q707 (replace with another direct one without testing)		Master Eletronica
SHARP	C 2057	Works for a few minutes and turns off, tsound is a drop in 5v	Check r 102 vlr 2k2 smd changing when heating		MASTER ELETRONICA
SHARP	C 2057	This TV was not bright, you had to raise the screen to see the image, but as soon as you turned it off the problem returned.	In this case it was a factory defect, as this model in stand by, the filament remains lit, and this ends up exhausting it more quickly, so put a jammer in place of the r 607, the c 607 also causes this defect, if not The solution could be the tube being exhausted.	Replace the s 607 with jumper, and replace the c 607	urbieta
SHARP	C2038 161	Does not oscillate +b does not have all voltages zero	Ic 801em curto		benedita
SHARP	C2188B	Vertical stretched at the top	C506 1000/35 e c504 1/63		Diego Uczak
SHARP	C1413	It doesn't turn on, the 115 volt +b only has 35	Troque or ci 701 tda 8380		Paulo Sertel - Itararé SP
SHARP	TVC 2013	The RF signal goes out (out of tune)	Altered t201 detector coil, perhaps damp, oxidized	Replace it for a similar one	Paulo Sertel - Itararé SP
SHARP	20ST58	Flyback with small leak, spark comes out around it and even in the cable and burns the vertical outlet	Black powder leading on the flyback and high cable	Lavar o flyback	joaomvjr
SHARP	C-2057	Flashing image	Put 100k resistor on pin 22 of ic 201 to ground, replace c 507 22mfx50v		HP ELETRONICA
SHARP	C2053 ?	Running away channels 5 and 13 as if it were the aft reel, sometimes it caught, sometimes it didn't catch	I replaced the eeprom memory and the problem was solved.		This email address is being protected from spambots. You need JavaScript enabled to view it.
SHARP	C-2038	Power supply works, high low voltage, when turned on it makes a sinusoid sound in the 16,12 and 13 v speaker with a difference of 4 to 3 v, tsound is no filament	When you turn on the TV, it starts with high voltage and goes down without a filament.	Check the two power supply capacitors +b 105v c725 and c727 in my case it was just the c725 saturated, so I went for the hug	ffeet
SHARP	C-2053	TV doesn't turn on.	Integrated circuit IC501(TDA3653) vertical output defective.	Replace the same.	jheliocavalcanti
SHARP	29ST54	No sound, weak color and upper black band	Ic 751 9v regulator	The regulator was stabilizing the voltage at 7v	Eletronica NDN
SHARP	C-14ST58	Vertical lines at the top	Rakh 05 (AR)		HAVAI
SHARP	C-1453	Audio does not work.	Ic 301	Replace.	This email address is being protected from spambots. You need JavaScript enabled to view it.
SHARP	29ST58	Burning of the horizontal output transistor and driver	1-check the value of the resistor of the base junction – emitter of the horizontal driver, which must correspond to 470Ω, changing the polarization resistor 2-in 29 st 58: r 605 from 560Ω to 470Ω; r 606 from 1 kΩ to 1.5 kΩ /4 w 3-no 29 st 98 : r 661 from 560Ω to 470Ω ; r 6l5 from 1kΩ to 1.5kΩ/4w		JOSE GUSMÃO
SHARP	20ST58	Noise at power supply on stand by	1-remove the capacitor included between pin 10 of t 3702 and q 3701, on the copper side of the PCI 2-include a capacitor in position c 3718 of 100 nf, polyester 3-include in series with the capacitor c 3718 a 10Ω resistor to ground 4-include in parallel with resistor r 3705 a capacitor of 1.5 nf x 2kv 5-in parallel with r 3727 install a capacitor of 1.3 nf x 2kv 6-in series with c 3744 add a resistor of 10Ω to land		JOSÉ GUSMÃO
