Make	Model	Symptom	Problem
SHARP	DV-3760S	Does not start, voltages always vary, LED flashes, does not oscillate	See and change the tr q605=bc636
SHARP	DV-3765 S -DV-3760H	Very weak image (negative type) beneath a red background and without luminance	Ver r616=22r + dz 608=22v + q 603 =bc557 + q 604=bc547
SHARP	81GF66E CHASSIS DA100W	It goes into standby very frequently, and sometimes the front LEDs flash, other times they don't	Tuner
SHARP	DV3765S CHASSIS 4BSA	TV without image and with return lines, RGB power supply ok, never gives an image by adjusting g2.	Replace ic501 (tda8170).
SHARP	CV5407	Sometimes it makes attempts to start or, starts and harnesses. correct power supply voltages.	Q605 (2sc1815) with leak
SHARP	63ET-01SN OU 70ET-01SN	No horizontal deflection	Replace mkp c-613 of 0.68µf/250v with one of 400v. also check r-613 of 2k2, and the resistance r-610 of 10Ω, as well as the capacitor c-619 of 2µ2/160 volts
SHARP	DV-3760S CHASSI 4BSA	Everything ok except not opening tuning mode	Defective eeprom
SHARP	DV-5450	Just stby, correct voltages but no oscillator signal.	C1006 (22uf) on/off circuit, I also found r621 (3k3) open
SHARP	37AM-12S	Doesn't work. +d voltage and 30v and all other supply voltages below 2v.	R704/705 560k open
SHARP	37EM-33S	Does not start (normal voltages)	Q209 (bc338-40) and q602 (bc636) damaged
SHARP	DV-3770S	Turns on, the LED turns green but the mat does not turn on	Replace the horizontal output transistor which after testing seemed ok
SHARP	37AM-12S	Turns on and off about 5 seconds later, lowers the +5v on pin 35 of the ic801	See q708=bc338 in the power supply output
SHARP	54 DT-25 SC	Vertical shrunken, q 502 and q504 overheating	Substituir r 508 - 33r (smd)
SHARP	63DS-05SN	Occasionally destroys lines output	L601 4.7uh change value (with signs of heating) c607 330 uf dry, check c723 !000 uf
SHARP	DV-3765	When cold, it takes time to start. The red LED flashes for about 30s until it starts.	C604 1000mf/16v with low capacity.
SHARP	CV-5130S	Does not turn on does not oscillate	Sub r625 = 100k
SHARP	DV-3765S	Stays in st-by and only starts after a while	Cnd c604 seco
SHARP	C-2053	Turns on and after a while it turns off. If you unplug it and plug it back in, it will work again for a few minutes and then disarm again.	Tube. I made a new bearing to power the TRC and it worked.
SHARP	C-1413	Stop. normal voltages and won't turn on	In the tda8360 noise.
SHARP	1453	Power supply with 50v and varying	The three 1r resistors open, place exactly the 3 1r resistors, it is between one pin of the fet and the ground.
