Make	Model	Symptom	Problem
GRUNDIG	ST70-713 = CUC2130	No image and dark osd with sound	Sub d54005 = 6,8v 1w
GRUNDIG	CUC7303	Lose sync. horizon. with weak signal, faded color	Subs. crystal 4.43. Attention it has to be high impedance otherwise it will be colorless
GRUNDIG	T51-645 - CHASSI G1000	When turned on it starts and runs, r116 changed	Sub r116 = 0,22
GRUNDIG	CUC7301	It only stays on by pressing the p+ key	T511 bc549 leaking
GRUNDIG	T51-070 CUC7301	Dark scene, does not control contrast or light	T523 bc548
GRUNDIG	VáRIOS	"crazy" functioning of the ypc, for example the sound goes down on its own, etc.	Replacing the switch may have a leak in the temporary contact, check the transistor t801, it may have a leak, it helps to stabilize if it drops r800 from 47k to 4.7k
GRUNDIG	CUC6300	Osd not horizontal direction	Capacitor c833 6n8 (ic811 pin 26)
GRUNDIG	CHASSIS G1000	Insufficient width, with blurred and horizontally folded image	Replace the microprocessor
GRUNDIG	CUC2030	Destruction of tsl t53001	D52001 c/ fuga 1n4148
GRUNDIG	CUC2030	At some point it goes to stand by	Poor welding no c53009 142pf mkp
GRUNDIG	CUC5350	Rich colors, and sometimes the timing fails. with scart the problem persisted.	Replace ic 2280 -- tda4452 on the if board
GRUNDIG	CUC2030	It doesn't turn on, when you press p+, the power supply seems to start up, ending up going back into standby mode. (voltages at the power supply output are all fine)	Ic 50020, tda8350q, short circuited. The 33r 1/2w r50011 must be replaced because it is interrupted and if the IC does not have +45v power, the protection kicks in and the TV will not start.
GRUNDIG	T51-4201TOP CHASSIS 12.5	The image becomes increasingly white and lacks definition.	Zener zd101 with leakage
GRUNDIG	MW70-2101 CUC2059	Systematic destruction of the power supply transistor t6006 (k2699)	Substituir r6001 (270 k)
GRUNDIG	CUC5303	No sound, you can only hear a low pink noise coming from the speaker.	Substituir t154 bc548
GRUNDIG	CUC4400	Power supply does not generate voltages.	Rataa - crimp
GRUNDIG	CUC7303	Low sound, control doesn't work	Defective infrared receiver ic
GRUNDIG	T63-530	Excess red color	Diode d746, on the trc board, with leakage
GRUNDIG	CUC5303	Sem osd	Transistor bc548 - t833 open at the e/b junction
GRUNDIG	CUC6300	Sound with momentary sound failures, sometimes the OSD appears blocking and it also happens that after a while it ends up with a white screen and no sound.	After checking and/or replacing the switch, memory and cleaning the printed circuit lines without obtaining results, the fault was resolved with a general wash of the chassis.
