Make	Model	Symptom	Problem
GRUNDIG	MW70-2700NIC/DOLBY CH.CUC2059	Doesn't start	T60006(irf-pc50),ic60010(tda4605/3),r60001 270k
GRUNDIG	CUC3400	The p+ key on the panel does not work, it does not go into stand-by.	Change the on/off switch.
GRUNDIG	CUC7851	Loading emergency data into IC850 EEPROM.	After changing the eeprom => connect pin 1 of the ic850 to the chassis and turn on the TV using the switch. the ic850 eeprom is loaded with the default data.
GRUNDIG	CUC7851	It works ok but when it turns off, if you try to turn it on again it won't start.	Change the eeprom that is on the zf board. If you put the empty eeprom it starts ok but tsound is no sound - it is necessary to load the emergency values.
GRUNDIG	CUC7303	Image with pulses in vertical synchronism	D444 (low voltage)
GRUNDIG	CUC6300	After a while the sound becomes noisy until it stops.	Electrolytic capacitor c377.
GRUNDIG	CUC5350	No sound, increasing the volume to maximum makes noise	I.c. msp2400
GRUNDIG	CUC6300	Image with abnormal color type switched in NTSC	Transistor t127
GRUNDIG	CUC5365	Image with floating ripple horizontally and out of position.	Transistor t522 (bc548)
GRUNDIG	T51-440 / CUC4400	It does not turn on, or it only turns on after a few minutes and works until it is turned off again at the switch. If it is put on standby it works ok.	C633 (100µf/25v) connected to pin 6 of the altered tda4605 - typical failure.
GRUNDIG	CUC5303	Tsound is no image. it is white with return lines. has sound.	Tr833 on line u/data. (typical of failures of that line)
GRUNDIG	CUC2103	No vertical linearity (image cut off at the bottom of the screen)	Smd transistor bc847, position ct50015 shorted between emitter and collector.
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.
