Make	Model	Symptom	Problem
GRUNDIG	DAVIO CHASSI BEKO 12.7	Power power supply. doesn't always start	C610 10nf (smd) with slight leakage
GRUNDIG	P37-830TEXT CUC7303	No video input through scart	Transistor ct840/bc848 short between base and emitter
GRUNDIG	CH CUC7303	Changes in tuning: is working well, starting to deviate slightly from the programmed tuning	Short circuit between the 33v line for the cr2853 and the tuning voltage for pin 2 of the tuner. replace one of the connections with an insulated wire. cut the other. Note: this happens on TVs that are in places with higher humidity.
GRUNDIG	T63-430 CHASSIS CUC4410	Without sound and/ image.	T2213 (bc338-40) in the I.F. module.
GRUNDIG	FAMILIA DAVIO CHASSIS 12.1 DA BEKO	Doesn't work. When turned on, it goes into protection. disconnect the x502 connector from the deflector, it no longer goes into protection and voltage appears on d607 (107v) when measuring diode d504 in the circuit it does not short	Ic701 stage final rgb
GRUNDIG	CUC4510	Out of phase horizontally, the 12v of the b' are slightly muffled.	T835 with leaks causes line b' oscillation
GRUNDIG	CUC5361	Image sparkling, jumps vertically, if you adjust rv freq. horizontally, the symptom decreased.	Replace or ic520, tda8214b.
GRUNDIG	CUC1893	Bright image at the edges, more pronounced the stronger the digital noise correction in the menu.	Open the feature box (100hz) remove the support IPs, clean the contacts. Due to the high heat of these IC's the supports swell, ultimately the support has to be replaced.
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	There is sound, there 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.
