stopped working the touch screen cf-19 mk1

#1 Post by zahar1968 »

Suddenly stopped working touch screen.
pointer does not move, how to check the serviceability of the sensor?
I opened the screen, check the connection.
I have experience with electronics.
How can I check and correct the problem?
very rarely sensor begins to operate.
Sorry for the text, write an interpreter
I live in Russia

1. Check connection under keyboard. Unplug and re-plug. (corrosion)
2. Possible broken wire in loom (this is group of wires with tape that wraps around swivel)<<<I think this one.
Good luck,
Jeff

Thank you for your reply.
1. It is necessary to raise the keyboard? How do I do?
2. Where comes bunch of wires on the motherboard?
In what place? Necessary to remove the motherboard to see?
When I find it, the tester will check the wires.
Can have pictures?

Thank you figured out.
Check the wires that are serviceable!
Checked the 4-wire touch screen
between two wires showed resistance Om 340
How much should it be?
touch screen is faulty?

Check continuity between white plug on left side of this picture and plug under keyboard to eliminate broken wire as cause.

I don't know the answer to the question about ohms.

Best option to work a long time is new touch panel. http://www.ebay.com/itm/NEW-TOUCHSCREEN ... 336d8069b2

Good luck,
