Kenwood question

Re: Kenwood question

LCD TVs are quite different to LCD modules like this.

In a lot of these modules, the panel drive happens on one chip-on-glass module which contains all GATE and SOURCE driver. However it's a dumb driver and must be controlled by the main board and also needs to be supplied the VGH, VGL, AVDD and VCORE voltages (approx +25V, -8V, +15V and +3.3V/+2.8V, though they may be lower/different for smaller panel.) It needs SYNC signals to update the display on time, 60 times/second.

So it's hard to use an LCD TV reference to say if this is a bad panel but my suspicion is it is not, and instead you're talking about a main board. BUT, I wouldn't rule out the LCD.

You always pick tricky projects.

Re: Kenwood question

I'm picking these projects, because nobody repairs these Kenwood units.
I may give up one day, but for now I give them a try.
Kenwood, charges $30 for a diagnosis, I may end up dropping it off.

Re: Kenwood question

I have got the other unit back and swapped the LCDs between them and it turned on as it should.
The panel and touchscreen are the same in both units and most likely in all the 6.1" Kenwood units.
It's the same one as in the Ebay link.
I just have to order that panel and unit it's done.
Thank you, for your input on this receiver.
