Make	Model	Symptom	Problem
SHARP	C-2006	The/ image, with/ sound	High voltage tripler
SHARP	C-1440B	Does not tune channel	IC1005 (ix37ce is a 33V zener)
SHARP	C - 1632B	This TV has no chroma	The problem was the leaky capacitor c-1053, which is indirectly connected to pin 6 of the microprocessor.
SHARP	TV SHARP14 DIGITAL	Works or turns off by itself power supply is low, if you open the screen it turns off	Causes shorted vertical output. I changed it and it was fine
SHARP	C-29ST58B	Completely off, just a horizontal light streak	Defect q-3701, tda8350 or d3718.
SHARP	C-1425-A	Green fabric	C-859 (10 µf 250 v) e ci-801 (ixo215)
SHARP	C-2006A	Only with a small horizontal band, with normal image and sound.	Case c-509.
SHARP	1452/2052B	Acting protection by turning off alone	Causes c-739 with its oxidized pins.
SHARP	TVC-2199B	Defect without high voltage	Measuring the power supply at pin 7 of the integrated ic-203 I found only 7v where there should be 12v. This power supply comes from the transistor q-702 where 15v should enter through the collector and exit through the emitter. As all of the chopper's power supplys were normal, it could not be a problem with the power supply's primary. I then replaced the c-731 capacitor and the TV started working. Perhaps this defect also occurs in models that use the ix0731 in the power supply.
SHARP	C-1453/2053	The defect in this television is its excessive height.	Cause resistor r-911 also check the electrolytics by replacing them with new ones. another defect the TV does not work ic-104 short or the capacitor c-616 defect without video tail probably diode d-601 with leak defect showing vertical stripes on the screen r-512 could also be an electrolytic capacitor. defect presented acting protection cause of defect d-611 with leak emitting a buzzing defect does not work stop causes ic-501 short. TV defect doesn't work varicap, that's not always the case, check the supply voltages and I found out that the varicap was killing the 5v voltage.
SHARP	C-1453/2053	Total inoperative defect shutting down the protection actuating	I replaced the special polyester capacitor c-666, which has a short. another defect presented was a closed vertical horizontal scratch, so I replaced the resistors r-618 and the capacitor c-618. Another defect that appears a lot on this television is the lack of color. How to solve this problem, replace c-811 and c-813 of 103 with 18pf. Check the channel selector meshes that give access to ground because if they are interrupted, they will also be discolored.
SHARP	C-2025	There is 300v at the collector of the 2sc2365 power supply transistor but nothing comes out at the emitter.	Check if there is a horizontal short, and everything will be fine. I decided to redo the soldering of the horizontal driver transformer. The good thing is that you check the entire board for cold solders.
SHARP	C-2025A	There is high voltage and the filament lights up but there is no brightness, sometimes the brightness appears and sometimes it disappears	Inductor l-605 which is connected to pin 4 of the fly-back. These inductors are usually altered with high resistance as well.
SHARP	C-2025	Power supply does not weapon	I checked the entire board and replaced the 100k r-704 resistance it was open
SHARP	C-1453	Acting protection i.e. switching off after one minute	Check the vertical output if it is shorted or the 22k r-727 resistor if it is damaged, this resistor is very critical
SHARP	C-2013	Turning off by itself, protection acting after 5 minutes	Replace all electrolytic capacitors in the power supply.
SHARP	2053	Stop	C-713 1nf or tda-8380 change them.
SHARP	TVC-11691B		C-709 2.2uf electrolytic capacitor.
SHARP	2040B	Stop	R-601 330r.
SHARP	SHARP C/ 2SC 2365 NA FONTE	Short power supply defect	Replace all parts that are shorted and replace the 10uf 450v capacitor, as this is what caused the power supply to burst.
