Hi I have a Acer aspire 9410 (9414wlsmi) 17 screen. The problem is that i have no backlight at all, i've bought a new screen + new inverter/backlight driver + new cable but it did'nt help i have...


The inverter/backlight combination isn't the whole picture. The inverter powers the backlight, but the inverter is controlled by a signal commonly called "Brite-On", which comes from the motherboard. If the "Bright -On" signal from the motherboard is missing,then the inverter (and thus the backlight) won't work. The problem you are having is on the motherboard. here's a link to a datasheet of such a device:

Whirlpool error code F50 who do I call ?


Hi,


F50 means that the Rotation Position Sensor doesn't sense any movement from the motor.
This test checks the wiring to the motor and rotor position sensor; and the motor and rotor position sensor themselves. NOTE: Drain water from tub.
1. Unplug washer or disconnect power.
2. Check to see if basket will turn freely.If basket turns freely, go to step 3. If basket does not turn freely, determine what is causing the mechanical friction or lock up.
3. Remove the console to access the machine/motor control assembly.
4. Visually check that the P5 and P10 connectors are inserted all the way into the machine/motor control. If visual checks pass, go to step 5. If visual checks fail, reconnect P5 and P10.
5. With an ohmmeter, check for 16 ohms resistance at the P5 connector between pins P5-1 and P5-2, and also between pins P5-1 and P5-3.Also measure the resistance at the P10 connector between pins P10-1and P10-7 and verify that the resistance is within the range. If the P5 connector resistance is much higher than 16 ohms, or the P10 connector resistance is out of range.
6. Tilt machine forward to access the bottom of the machine and the drive motor area. Remove the motor bolt, then the motor cover to access the motor connections.
7. Visually check the mounting bracket and electrical connections to the motor and rotor position sensor board. If visual check fails,reconnect the electrical connections, reassemble stator and motor cover.
8. With an ohmmeter, check for continuity between all pins on the P10 machine/motor control connector and the motor rotor position sensor (RPS) connector.If there is no continuity,replace the lower machine harness.
9. With an ohmmeter, check for continuity between all pins on the P5 machine/motor control connector and the drive motor connector.If there is continuity, replace the drive motor.If there is no continuity, replace the lower machine harness.
10. The drive motor and lower harness are good. Replace the motor RPS board and perform the Diagnostics test.
11. If the Diagnostics motor failed, then the machine/motor control has failed: Unplug the washer or disconnect power.Replace the machine/motor control assembly.


Thank you !!

I was chaging setting and I turned of backlight


If its just the backlight then you can stay in a well lit area and look at the screen that way to change the setting, also you could try plugging it in to keep the backlight on.

Dell monitor 15 inch the green light stays on but no picture


It's the backlight supply tripping out from backlight failure, but the thing still stays on. I got it to act right by switching to factory presets with some fast menu action once, but the general solution is going to involve tricking the backlight into staying on; you can look at the thing in bright ambient light to see that the display is still working, but of course without a backlight it's pretty much useless.

Since $100 buys a better and more efficient monitor, just replace it; otherwise of course you can either replace the backlight (or go for one of the projector mods) or convince its drive circuit to put up with it a bit longer. I spotted a bad capacitor but swapping that out hasn't gone well yet....
