Re: Sharp Aquos LC46XL2E LCD (2 flashing lights)

Hi,

I have the service manual and it includes the partslists of all boards. Can neither find the cap C4707 nor the IC4701.

I cannot find that service manual, can you post a link to it?

Any ideas? After switching it on i can hear a kind of tickering near the inductors at the bottom right edge. There is IC9601 which should provide the 3.3V, but it doesn't.

Regards

Sorry -- totally missed your post.
What do you get across C9634?

Re: Sharp Aquos LC46XL2E LCD (2 flashing lights)

Can't measure exactly because when the set ist turned off because of failure the voltage will be switched off. But after pressing power button the voltage jumps up. On standby the voltage is 0V.

Re: Sharp Aquos LC46XL2E LCD (2 flashing lights)

As far as I know a Sharp LCD will just freeze the startup process should a fault occur, so the 3.3V, if it works, should come up and stay at the right value, or a wrong value...

Re: Sharp Aquos LC46XL2E LCD (2 flashing lights)

So in this case there must be the wrong value. Is there a difference between Digital and analog 3.3V? And where could I measure these voltages?

[tom66]

Re: Sharp Aquos LC46XL2E LCD (2 flashing lights)

Digital 3.3V and analog 3.3V may be separate.
Check pin SS (#6), or across C9602 (near the IC), should measure 3.7V when working.

I am having a problem similar but not the same and it is my hope someone here can help. I have a 50" Sharp Aquos and I am absolutely sure that only one green light is on the front of the tv when it is on normally...but today there are two lights and I swear the picture seems darker?? Anyone have any thoughts?

You must have OPC enabled

Go to Menu and disable it you should be OK

Re: Sharp Aquos LC46XL2E LCD (2 flashing lights)

You can start by downloading the service manual from elektrotanya, it is about 65MB so I cannot upload to BC.

Re: Sharp Aquos LC46XL2E LCD (2 flashing lights)

Im unsure what im looking for. Im not even 100% sure its the right manual i found.
