Recently, fans have been asking me, "sensei, my tv is black, it's not working. "don't hurry! Just follow me one step at a time, 90% of the cases will be solved

1 power module failure (45%)
2 fired fuses (20%)
3 software dead (15%)
4 ️⃣ keyboard failure (10%)
5 poor access to external circuits (10 per cent)
I'll show you my hand
Tool preparation: all tables (electronic also), screwdriver (cross/one word), insulation tape
Step 1: preliminary judgement
1 confirm if the plug is electric (light light with mobile phone)
Two, hold the power button for five seconds to see if it works
3 try remote control + key double
Step 2: in-depth testing (focus!)
Take it off and cover it off
Found the power module (long smudge)
(normal 3. 3-12v)
Inspection of fuses (type f101/f102)
See if there's any burns on the main panel
Step 3: final validation
Restart circuit board: two minutes after power cuts
Update system: enter project mode (code required)
Cleaning of circuits: tampons with alcohol wipe interfaces
Don't do this
Change main panel directly (high-cost roller)
Welding elements with electric branding (possible to increase failure)
Forced start-up test (damaged main panel)
Correct: power out! Then test! Last repair
