weyia 826

[alienware32]

i have a weyia 826  all is working except the brightness pot on the remote board any ideas what wrong with it

[Kevin Mullins]

Is it TOO bright ?

[alienware32]

yes i can only adjust it with the flyback

[Kevin Mullins]

So if you turn the flyback down.... the brightness pot makes no changes still ?
(if you overdrive it with the flyback, you'll never see a change)

Is there a contrast pot ? Is it cranked up ?

Starting to sound like you have a bad pot.... just trying to verify or at least narrow it down.

[alienware32]

no change at all and theres no contrast control

[Kevin Mullins]

Measure the resistance on the pot itself.

1       2
   
     3

1+2 gives overall value of the pot.
1+3 or 2+3 should vary from overall value down to zero when adjusting pot.

Best to remove the pot for testing.

[Kevin Mullins]

With a multi-meter...... Ohms.

i measured it the pot is fine i think it something on the chassis

[Kevin Mullins]

So is the value on that pot ?

[alienware32]

i think it the chassis the pot value is fine

[Kevin Mullins]

I was going to compare your readings against what it should be......
Do you have a schematic or manual for that chassis ?

[alienware32]
