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.

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.

It only turned on without the vertical ci In my case, the problem above was solved by changing the horizontal oscillator ci. tip sent by: laureano
