50PB560B Repair Guide: Common Issues and Fixes
| Brand | Model | Fault | Detailed Problem | Solution | By |
|---|---|---|---|---|---|
| LG | 50PB560B | pictureless | Defective Controlling Plate | Replace Controlling Plate | Eletronica NDN |
| LG | 50PB560B | pictureless | YSUS in short | replace Q552, Q554 both SMK0460, R561 - 10 Ohms, C672 - 102K 1KV, C671 - 471K 1KV, D556 ES1G, IC 551 - P155E, D552 - CDZ55C56, comes only 56 in the zener 56V 500MA encapsulation | Eletronica NDN |
| LG | 50PB560B 00000 | Just one image pulse then erases | C 205 smd with leakage below r 201=2.2Ω | Replace without testing * good luck! | Jhone eletronica |
| LG | 50PB560B | Turns off and on (restarts) with operating time of about 20 minutes | *only detected on the open Globo channel, on other channels and HDMI works normally | Via the remote's common menu *options*interactivity (dtvi) deactivate the function and solved the problem. due to some incompatibility of the interaction with the video circuits, it goes into protection causing a restart. resolved* helping strengthens! | |
| LG | 50PB560B | No image | On the p131 connector tsound was vs and va, but tsound was no 18v on the y-sus board | Q507 and d502 shorted near the 220k resistor. | Eletronica EASI |
| LG | 50PB560B 50PB650B 50PB690B | Does not turn on, only 5v standby, when activating the power the standby flashes and comes back on. without va, without vs, without 18v. auto-gen does not activate. | After inspecting the y-sus, z-sus and trying the auto-gen on ctrl bd, without success, I checked several cold soldering points on the power supply PCI, in addition to the IC that switches the va and vs voltages in short. | Complete resoldering of the power supply, replace ic801 (ncp1397bg) | WorldTV + Eletronica Tecnotronic |
| LG | 50PB560B EAY63168602 | TV turns on looks like the logo with a weak image or full of red dots then goes into protection | Defect is a double diode showing low anode resistance for catode 150 to 190 homos, the correct one is that it presents a resistance of 390 homos upwards as an fcf10a40 was used instead and resolved the defect or use an equivalent in the place, this diode is in the el40 position on the board. power supply wsound it feeds tension from you. | Bruno trindade | |
| LG | 50PB560B | Image disappears after 10 to 15 minutes | Check c445 | Arnaldo Murta | |
