Make	Model	Symptom	Problem	By
GRUNDIG	CUC7350	Screen without brightness. increasing ug2 appears white with return lines and little width. ht voltage drops to 65v. I test with a 60w bulb, it doesn't light up.	R60028 from 0r56 changed to more at about 0r20.
GRUNDIG	CUC7880	Defect and/or	R503, l511, diodo d438 (33v) e ic430 (tda8350q)
GRUNDIG	CUC7350	When turned on, the image appears with a lack of vertical synchronization. after a few seconds the STBY drops	Transistors ct58006 and ct58007 (smd)
GRUNDIG	CUC7303	Tsound is sound, tsound is no image. When the screen is enlarged, light appears with return lines but no video.	Shorted transistor t523.
GRUNDIG	CUC7301	Lack of vertical sync on the OSD. is always passing by	R404 (33k) on v sinc line. that goes to the processor. (smd match)
GRUNDIG	P37-845 FR CHASSI CUC7300	W/o sound with non-standard image	Sst 19 = bsakkhas
GRUNDIG	CUC6360	After a while it switches to av1 or av2	Tfms5300 ir receiver
GRUNDIG	T51-070 CUC7301	Falls into protection. hang up	T511 = bc548
GRUNDIG	M84-210/8 IDTV CUC1827	Image shows wave probe type	C53312 = 142pf 2000v
GRUNDIG	T50-440 CUC4400	S/ synchronisms	Mod fi t2243 = bc548
GRUNDIG	TVR3740/1 TOP	Does not turn on, stays on st/by	C840 47uf 63v
GRUNDIG	CHASSIS CUC7303	No image appears on the screen, if we increase the voltage of the g2 the screen becomes dark, and the return lines appear.	It could be r118 of 4.7Ω, ¼ w, interrupted, this resistance is in the supply of ic 105 (smd) tda4662, the same can happen to r119.
GRUNDIG	CHASSIS CUC5310	Flickering in the image, light variations.	The capacitor c681 4.7mf 350v, disabled, this component is inserted in the +c 200v voltage circuit.
GRUNDIG	CUC6300	At startup it generates mat but within 1s it returns to stby, leaving no +b` (output from the ic676 lm317) and no line signal.	Replace trc. it was shorted.
GRUNDIG	CUC4400	Power supply does not generate voltages	C661 and c662 with low capacity. to replace.
GRUNDIG	MW70-2700 16X9	Doesn't work.	Cause r 220k which is part of a set. of series parallel resistances in sec. from open power supply, which causes the t60006 irfpc50 to short out
GRUNDIG	CUC4400	T644 systematically shorts out	C680 with leak
GRUNDIG	CUC7303	It does not start, the power supply does not generate voltages in the secondary, it only has 300v.	See r663 of 10r 1/4w in the primary, it may be interrupted.
GRUNDIG	G1000	It ticks, the power supply does not start, the secondary part of the power supply is fine!	See and replace the c111 1nf/1kv. This capacitor is connected between the collector and the ground.
GRUNDIG	T63-640A TEXT CUC6310	Tda8145 with excessive heating and the rv’s, e/w adjustment r462, 460 and 431 do not work.	L569 with shorted turns due to excessive heating caused due to a previous fault on this line. or, d566 shorted. Also check the following components: c461(100mf/35v), c412(1000mf/35v and c413(1000mf/35v). rewind l569 using new wire.	Duartes
