Couple months ago i had problem with SHARP LCD TV LC-32DH66E that won’t turn on.
Symptoms: power up was slow, and getting slower over time until stop won’t turn on (green led)
TV have inside build in self-test that should show source of problem by blinking led in pattern described in service manual.
Unlucky problem is, failed capacitor don’t trigger this error warning.
Fix is very simple, replace showed capacitor – i decide to use other form factor so hope it won’t come back again.
To access capacitor You have flip board back, it’s under PSU control IC.
