Yesterday, the user sent a 29-inch flat-screen LG TV, and the fault phenomenon was three. The user said that this phenomenon is the third time. The first two times were to find another master nearby. It would be nice to spend 80 yuan each time to change something, but telling not to use the remote control to shut down, it is very inconvenient. However, the time spent is not long, about half a year. I am looking for you to repair this time, I would like to ask if I can repair the original circuit. After listening to him, I already have a number in my heart. I can say it, but the repair cost is more expensive than that of the master. I want 150 to restore you the same as the original machine. The user readily agrees, saying that as long as it is repaired. After disassembling, it was found that the insurance was in good condition. The power supply was equipped with a 5-wire module. The circuit did not lack any components, but only one capacitor was missing. Remove the 5-wire module, solder the module I used for the test machine, and simply start the booting. Normally, just fix the power supply. Look for the drawing, the original machine power thick film is STR-F6654, connect 200W bulb in the fuse, find a F6656 installed, solder 100W bulb in the positive B capacitor to make a dummy load, the boot load bulb can be bright, but the voltage is 50-70V Bounce, test F6656's 4 pin voltage 12V is low, further check that R803 positive feedback current limiting resistor is open, replace a 10 ohm resistor, boot everything is normal, at this time F6656 4 pin voltage 16.8V. The original machine is a very simple problem, some people just like to use the module, and therefore permanently lost this user.
Description of Stacked D-Sub I/O Connectors
Antenk's connectors are designed for applications requiring multiple connector ports with limited PCB space
The condensed footprint of Antenk's dual port D-sub solution is available in four industry sizes, three connector spacing options, and six hardware configurations for one of the broadest stacked D-sub offerings on the market in standard and high-density variations.
Stacked D-sub I/O connectors are designed for applications requiring multiple connector ports with limited PCB space. Two right angle D-sub connectors are stacked one on top of another, creating a single dual-port connector with a very condensed footprint.
Features of Stacked D-Sub I/O Connectors
