the LED not lighting is your first clue
odds are its also not reading the lid switch
look for a missing signal to IC501

I can not find the datasheet for ic501 (NEC D91317GD)

Have you ??

What pine I have to do the test ????

Thank you for your help

Hey
I do not have a laser beam
I replaced 2 6290. nothing has changed
I also changed the lens. Nothing has changed

I measured the resistance that gives me 4.67k

Is it the right value?
What is the component that activates the cd?

Good morning,
I followed the work carefully.

I tested the voltages that occur on the moteus, optical block. Everything seems ok
I make a cap head kit.

When I press run on the screen tells me "just a moment" and nothing else happens
Red led does not light

I have the impression that there is a command does not arrive at a component

I found the values in OHM

Vr101 = 12.56 kohm
Vr102 = 968 ohm
Vr103 = 3.22 kohm
Vr104 = 4.66 kohm
Vr105 = 2.13 kohm

If you have an idea???

Thank you for your help
