GRUNDIG Repair Guide: Common Issues and Fixes
| Brand | Model | Fault | Detailed Problem | Solution | By |
|---|---|---|---|---|---|
| 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. | ||
| GRUNDIG | T51-4201TOP CHASSIS 12.5 | The image becomes increasingly white and lacks definition. | Zener zd101 with leakage | ||
| GRUNDIG | MW70-2101 CUC2059 | Systematic destruction of the power supply transistor t6006 (k2699) | Substituir r6001 (270 k) | ||
| GRUNDIG | CUC5303 | No sound, you can only hear a low pink noise coming from the speaker. | Substituir t154 bc548 | ||
| GRUNDIG | CUC4400 | Power supply does not generate voltages. | Rataa - crimp | ||
| GRUNDIG | CUC7303 | Low sound, control doesn't work | Defective infrared receiver ic | ||
| GRUNDIG | T63-530 | Excess red color | Diode d746, on the trc board, with leakage | ||
| GRUNDIG | CUC5303 | Sem osd | Transistor bc548 - t833 open at the e/b junction | ||
| GRUNDIG | CUC6300 | Sound with momentary sound failures, sometimes the OSD appears blocking and it also happens that after a while it ends up with a white screen and no sound. | After checking and/or replacing the switch, memory and cleaning the printed circuit lines without obtaining results, the fault was resolved with a general wash of the chassis. |
