Restart Issue Due to Main Board Fault
LG 32LK330 Restart Problem Fix This LED TV came to the Sony LED Repair Center for repair. As soon as I turned on the set, the display would show and then restart again. The fault was also appearing in its display; that is, the LG logo was fine on half the screen, but below it, the logo was showing in a double image. I took the time from the customer to diagnose this fault and kept the set on the lab table to be repaired the next day.
LG 32LK330 Voltage & Resistor Testing
I opened the back cover of this set and first checked its voltage. All the voltages of this main board were OK. This board had a NAND flash and two RAMs along with the system IC. After the initial inspection, i.e., voltage testing, I started checking its resistors. Many array resistors were going from the system IC to the two RAMs, whose values were 56 ohms and 22 ohms. Among these RAMs,
22Ω Resistor Replacement Fix
One RAM whose chassis number was IC1202 had an array resistor with the same RAM whose value was 22 ohms. This was defective. I did this. 22 ohms If I replaced the resistor, my fault would be fixed. The image on the screen would also be perfect. I even ran it on a test run for a long time to confirm that my fault had indeed been fixed. It was completely correct. This way, my job will be done and the customer will be satisfied.

Conclusion
LG 32LK330 Restart Problem Fix It was not just a restart fault, but there was also a problem with the image on the screen. We fixed this fault by replacing the 22-ohm array resistors on the main board. Sometimes even a small part can cause the entire circuit system to malfunction, so we should check even the smallest thing very carefully.
Q&A
1. Why does the LG 32LK330 keep restarting even when voltages are normal?
A: 1 Take the example of the same case where all the voltages were fine and the fault was a malfunction between the RAM and the system IC, which we fixed by replacing the bad resistors.
2: What roles do resistors between system IC and RAM play in TV malfunction?
A: 2 Some processors have external RAM; in such ICs the role of these array resistors becomes very important.
3: Can replacing a 22 Ω resistor really fix a restarting issue?
A: 3 I guarantee this specific model because I did it myself. No content is published on this website that is not authentic.
4: How long should I test a TV after repair to be confident the fault is cleared?
A: 4 I’ve run this set for eight to ten hours, and it’s been working perfectly.
