I have a power roll 2, and it just quit working, no light nothing any suggestions?

Here is your answer from Just Answer. Exactly the same issue and caused by the 'RAP Relay' (Retained Accessory Power).

It is located in the Passenger Side Fuse Box.

Sounds like you have a completely dead battery or the connection to your battery is fubar.

Check the fuse for the radio. There are 2 of them.

Empty cartridge maybe?
Otherwise it's simple: selt-test page(by printer button) printed ok - it's outer problem. Self-page is blank - it's inner problem. And so on... use Golden Section method

PS-79C Issue was the bin light came on (when the bin was out), but the power wouldn't come on and no other lights. Just called the 800 number above (800-945-4545) and was told to jiggle the power switch - worked!! (The power switch on the top, not the one by the power cord). I guess it doesn't quite seat onto the internal circuit board switch quite right. Yay, working again! Then I got lectured to oil it once a month or every bin full, which I haven't been doing...

turn it on then push the joystick forward till it beeps then pull it backward till it beeps then it will unlock. chair is in lockout mode

just check your laptop battery remove the battery once for 2 min

if this will not help try

step 2 check your Acer Laptop charger pin

roll the pin of your charger about 90 - 180 degree after attaching into

your laptop if it works then you have to contact your nearby service

center to alignment power jack of your laptop that attached to the

motherboard.

hope this can help you

if not

contact me with full details like

after attaching the power pin did you find any power light yes / no

did your charger show any light indicator yes / no

thanks

Hi

Thanks for using FixYa. Please check the following—

1. Is Power board output +5V?
2. Is J1 (#19 in the right diagram)connector good?
3. Is DC-DC OK, check the voltage at J1 using a multimeter.
4. Is U4 (3.3V) working ok, U4 is an IC, you’ll need an IC tester or an oscilloscope to check this IC.

After checking this if it still doesn’t work then check P3 D-sub Input (on the D-board). See this schematic for details--









Please do accept the solution if the issue is resolved or else revert for further assistance.


Thanks

Sounds like an internal fuse to me.

Hello;
It sounds as if the main power lead could be loose powering the dash. There are several main power blocks, make sure your connections are clean and tight. I have seen the circuit board for the dash fail but not often. Hope this helps.
Thanks;
