The touchpad itself is probably fine. The problem will either be in the display PCB or the main PCB. Also a good idea to verify the power supply (wall outlet) is good. 

You would need to do some voltage checks to determine which board is faulty. Do you have the service manual?

[Tegpaul]

Yes, I do have service manual for this appliance,

there is also F-1 flashing on screen, could be error code,

i checked few websites and found out that display PCB and main PCB are discontinued, so don't available any more.

Thanks!

Okay that leaves only the field repair option. Use the schematic to figure out which board isn’t supplying voltage for the display and then replace the capacitors in the DC power supply on that board. Yeah, kind of a crap shoot but with the needed parts being NLA, it’s either that or buy a new range.

I am not that professional but definitely will try before throwing it away, so it will either work or definitely be trash.

I noticed Radio Shack stores closed around my neighborhood and now they have minimum order requirements for free shipping on their website.

Can you please advise where should I buy cheap capacitor,resistance or other things for field repair?

Please advise!

Thanks!

Bing around online. Mouser electronics is usually pretty good for this.

Core centric solutions  may have a Remanufactired board for you . Look them up. They sell remanufactired appliance control boards. If they don’t have one in stock then you send yours in to them for fixing. They come with a 6 month warranty also . I have used them a couple of times
