Introduction
Go to step 1 ↓The LED light bulb consists of many small LEDs connected in series. Whenever a single LED gets fused, the circuit is broken and the Light bulb stops functioning, even though most of the LEDs are still in working condition.
Use this guide to repair a fused bulb by easily replacing a fused LED with a new LED and completing the closed circuit through which the current flows again and lights the bulb.

I have a large LED bulb with 8 banks of LEDs. The bulb would flicker at times then stay illuminated for a period. After a short time doing this it would completely stop then come back on. It finally stopped working at all. I engineered myself a couple leads from some old multimeter leads I had collecting dusk. I attached those to a fresh 9v battery then checked each bank of LED. All illuminate as quickly as I touch the leads to the first LED in each bank. What’s the issues with this bulb? It’s not due to a bad LED and breaking the continuity. I also prior to testing with the battery went through each bank getting a solid tone so there’s no loss of power from ATo Z. I’m open to suggestions based on your experience tackling this issue. It’s my first rodeo with the LED bulb. Thanks for your help.
