GRUNDIG Repair Guide: Common Issues and Fixes
Brand | Model | Fault | Detailed Problem | Solution | By |
---|---|---|---|---|---|
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. | ||
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 there 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 | There 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. |
