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. | ||

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 | |

T63-640A TEXT
CUC6310 |
Image very cropped on the sides and half-moon. | C567(360nf) totally disabled | Duartes | |

ST63-640 CUC6310
CUC6310 |
Image very cropped on the sides and in half moon, e/w adjustment res r462,460 and 431 do not act. tda8145 with excessive heating. | Power supply of fault l569 with shorted turns, or d566 shorted, check tda8145, check c461 (100mf/35v) - c412(1000mf/35v)- c413 (1000mf/35v) | Duartes | |

GDR5400
|
Device completely inoperative, 12v v953 regulator very hot. | Regulator v953 very hot due to short circuit, the culprit was identified: capacitor c605 on the board containing the tuner with a resistance of 0Ω. sent by: mfm | ||

GV400 / GV440
|
Display shows "locked" sometimes timer is blinking | Cassette loading is at fault, replace loading gear complete | ||

M70-1690 CUC6369
|
Dead, si621 1.6amp blown apart | Replace si621 1.6a, si601 2.5a, d620 b380 c2000/1500 rec, t644 irfbc40 mosfet, ic631 tda4605-3, c633 100uf,25v, this was caused by dry joints on c648 | ||
| GRUNDIG |
8214
|
Poor linearity / vertical deflection problems | Check +d voltage on pin 12 of the vertical deflection module. if this voltage is less then 35v or has ripple replace c628 3300uf, 50v, also check fuse si627 t3,15a. sometimes this fuse has resistance causing a voltage drop across it | ||
| GRUNDIG |
CUC3500
|
No sound av-mode sound ok | Replace ic2210 u2829 | ||
| GRUNDIG |
CUC4400
|
E.h.t very weird, e.h.t. transformer makes strange sound, no image | Measure pin 1 of the tda2579, if there are vertical pulses then measure pin 11 of the tda2579 for hor. pulses, if missing, or voltages are very low mv replace the ic. the ref. voltage on pin 12 will be present if the tda2579 works correctly. measure on pin 10 of the ps | ||
| GRUNDIG |
CUC4400
|
No image from tuner. image from av input rgb is rolling over the screen no synchronisation | Check if teletext is present at the top of the screen. if this is ok replace the tda5931 normally the sound will also be missing | ||
