इस वीडियो में जानिए कैसे करें #MicrowaveOven PCB की प्रोफेशनल रिपेयरिंग, जिसमें खराब हो चुकी #LNK364PN IC को बदला गया है।

अगर आपके पास LNK364PN IC नहीं है, तो उसकी जगह कौन-कौन सी alternative ICs लग सकती हैं — वो भी हमने बताया है।

हमने external power supply से MCU को कैसे चेक करें, यह भी step-by-step डेमो के साथ दिखाया है।
साथ ही यह भी बताया गया है कि PCB पर आने वाली *output voltages* को कैसे पहचानें — कौन सी लाइन 5V DC है और कौन सी 12V DC।

देखिए कि relay output आ रही है या नहीं, और #RelayTest करने का सही तरीका क्या है।

📌 वीडियो में शामिल प्रमुख टॉपिक्स:
LNK364PN IC replacement
External power supply से MCU check करना
Output voltages की पहचान: #5VDC vs #12VDC
Relay working test
Alternative IC options

English:-
In this video, learn how to repair a MicrowaveOven PCB by replacing the damaged LNK364PN IC step by step.

We’ve also explained which alternative ICs can be used in place of LNK364PN in case you don't have the exact part available.

Using an external power supply, we show how to test if the #MCU (microcontroller) is working properly or not — even when the main supply is not active.

You’ll also learn how to identify the output voltages on the board — which line is 5V DC and which is 12V DC — with a clear voltage testing method.

We demonstrate how to check if the relay is switching correctly and whether the output is coming or not.

📌 Key topics covered:
LNK364PN IC replacement
External power supply testing for MCU
Identifying 5VDC vs 12VDC output
Relay output testing
Compatible IC alternatives
