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