Tcl L49S6500 dead fault When this set (Tcl-L49S6500) came to me, it was showing 12 volts and 5 volts. The 5 volts were going to the 3.3-volt buck converter, but the 3.3-volt output was extremely low, showing only millivolts. Upon checking, I found that the 3.3-volt line was shorted to ground. After further investigation, I
Sony klv-50w652d dead condition System IC in this Sony model There are two reference points By making two sets of voltage dividers resistance 1 kilo ohm If the reference point system of both the voltage dividers goes to this then this system operates as In the second case, the system is not operate like this,
SONY GT3 POWER SYPPLY REPAIR The power supply of the Sony LED TV model KLV-32S550 was fluctuating. The feedback reference, which should be found at pin 2 of the CXD9841P, was missing. This reference is generated by the TL431, and the voltage divider resistors were found to be faulty. Using a TL431 as a
KLV-40W652D The Sony KLV 40W652D television had a fault where it was completely dead. The issue was found to be with a 75-ohm resistor, which was faulty. After replacing the resistor, the television started working fine. This resistor connects the NAND flash to the system. Facebook page WhatsApp Pinterest Expert Sony led TV Repair Center
SONY LED TV REPAIRE CENTER It seems like you are referring to DDR4 (Double Data Rate 4) memory, which typically operates at a nominal voltage of 1.2V. Key Points About DDR4: 1. **Voltage**: DDR4 memory operates at a lower voltage of 1.2V compared to its predecessor DDR3, which operates at 1.5V. This reduction in voltage
