Hello,
I have a Switch with no backlight. Board is HAC-CPU-10. Upon inspection I found a row of diodes pretty much the reverse side of the backlight connector. Three of them have lifted (Probably when replacing USB port). Volt drop is 1.1V Fwd bias and 0.5V Reverse bias, so I assume short? I’m using diode test on a Fluke meter but in circuit. R is 400K.
Anyone had a similar issue before?
What value are they?
Thankyou if anyone can help.
