GRUNDIG Repair Guide: Common Issues and Fixes
| Brand | Model | Fault | Detailed Problem | Solution | By |
|---|---|---|---|---|---|
| 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. | ||
| GRUNDIG | CUC7350 | Screen without brightness. increasing ug2 appears white with return lines and little width. ht voltage drops to 65v. I test with a 60w bulb, it doesn't light up. | R60028 from 0r56 changed to more at about 0r20. | ||
| GRUNDIG | CUC7880 | Defect and/or | R503, l511, diodo d438 (33v) e ic430 (tda8350q) | ||
| GRUNDIG | CUC7350 | When turned on, the image appears with a lack of vertical synchronization. after a few seconds the STBY drops | Transistors ct58006 and ct58007 (smd) | ||
| GRUNDIG | CUC7303 | There is sound, there is no image. When the screen is enlarged, light appears with return lines but no video. | Shorted transistor t523. | ||
| GRUNDIG | CUC7301 | Lack of vertical sync on the OSD. is always passing by | R404 (33k) on v sinc line. that goes to the processor. (smd match) | ||
| GRUNDIG | P37-845 FR CHASSI CUC7300 | W/o sound with non-standard image | Sst 19 = bsakkhas | ||
| GRUNDIG | CUC6360 | After a while it switches to av1 or av2 | Tfms5300 ir receiver | ||
| GRUNDIG | T51-070 CUC7301 | Falls into protection. hang up | T511 = bc548 | ||
| GRUNDIG | M84-210/8 IDTV CUC1827 | Image shows wave probe type | C53312 = 142pf 2000v | ||
| GRUNDIG | T50-440 CUC4400 | S/ synchronisms | Mod fi t2243 = bc548 | ||
| GRUNDIG | TVR3740/1 TOP | Does not turn on, stays on st/by | C840 47uf 63v | ||
| GRUNDIG | CHASSIS CUC7303 | No image appears on the screen, if we increase the voltage of the g2 the screen becomes dark, and the return lines appear. | It could be r118 of 4.7Ω, ¼ w, interrupted, this resistance is in the supply of ic 105 (smd) tda4662, the same can happen to r119. |
