GRUNDIG Repair Guide: Common Issues and Fixes
| Brand | Model | Fault | Detailed Problem | Solution | By |
|---|---|---|---|---|---|
| GRUNDIG | MW70-100/8 | R53021 burns systematically when starting | Substitute coil l 53021 | ||
| GRUNDIG | P37-070 - CUC7301 | The/ image, and/ sound via rf, normal via scart. | Ct840 (bc848) | ||
| GRUNDIG | CHASSIS CUC6300 | Without image, with osd, and in text versions, also teletext | T277 bc548b leaks | ||
| GRUNDIG | CUC5360 | Does not capture VHF, captures UHF with little gain | Tda5931 intermediate frequency | ||
| GRUNDIG | CUC7851 | Wrong layout on the chassis - the printing of the d438 - zener zpd33 - on the soldering side it has the cathode for the ground, it's wrong | When replacing the zener you will have to pay attention to its position | ||
| GRUNDIG | CH CUC3400 | Burns t661 but11a/12a | C667 2.2uf 450v (in the mod that is electrolytic) | ||
| GRUNDIG | CHASSIS G1000 | Image with contours of the image "figures" with tracery | Substituir c. int do vertical tda8170 | ||
| GRUNDIG | M63-105/9 IDTV CUC1822 | Every now and then it turns off. can work more hours at a time | Transfer. chopper, feedback section. of the defective primary. 29201-403.97 not yet available by hr. it has to be original | ||
| 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. |
