The solder that joins the light supply from the board to the screen is severed. Try soldering it back.

How to hard reset my Canon MF4150? It lost power while updating firmware and now all the lights are on with no display on LCD.

If you lost power in this situation, then sadly it is unlikely that you can recover from it, as the camera has no working software to tell it what to do. This is why the instructions for upgrading firmware specifically state to use mains power or a fully charged battery.

Diagnosing a LCD blank screen problem.

Recently a 3 year old VIzio TV I bought started having problems. The set would turn on normally for a few seconds then the picture would go dark with everything else operating normally including sound. Remembering a similar laptop computer problem I diagnosed previously, I immediately suspected a defective TV screen backlight. To verify this in your own TV, get a very bright flashlight and with the TV operating in the failed blank screen mode, shine the flash light into the blank screen from various angles and distance (including touching the screen). If the LCD is still operating, you'll see a dim motion in the flashlight's reflection, thus proving it is indeed a failed backlight.

The washer flashed fh the door locked and it is trying to pump water out and no water is going in we just moved in to a new house and the water pressure is really hi my e mail is


Thanks for using FixYa. Error code F/H means no water was detected entering machine or Pressure switch trip not detected. If after 30 seconds the control does not detect water entering machine and then valves will be turned off and the error code will be displayed. It can also happen if the control has turned the water valves on and after 8 minutes the flow meter has detected 10.5 gallons of water passing through it, but has not detected the pressure switch trip, the valves will be turned off and the error code will flash. You'll need to Press PAUSE/CANCEL twice to clear the display and then check:

  1. If there is no water in the unit:
  2. Make sure that both valves at the water source(s) are turned on all the way.
  3. Check for plugged or kinked inlet hoses or plugged screens in the inlet valves
  4. Verify inlet valve operation
  5. If there is water in the unit:
  6. Verify Drain pump operation
  7. Pressure Switch Hose is in good condition and properly connected to Tub and Pressure switch
  8. Verify there is not a siphon problem
  9. Verify wire harness connections to; Inlet Valves, Pressure Switch, Drain Pump, Flow Meter and Central Control Unit (CCU)
  10. Check all hoses for possible leaks
  11. Verify pressure switch operation
  12. Verify flow meter operation
  13. Verify CCU operation

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

Monitor L17AMTN flashes WinXP desktop, then blanks.

dmellman, Before you open it up, try this! With fully booted pc and WIN DESKTOP screen up, reconnect the L17AMTN . Have a bright flashlight handy so that when the lcd screen flashes on for 1 second and then goes dark, you will want to check to see if the desktop remains on the screen even though you think it went away. Shine the light 1-2 inches from screen at different angles. Has the desk top completely disappeared or is it still being displayed? Do you know about Cold-Cathode-Fluorescent tubes and their Inverter type power supply? I assume that this unit also has a "lay on floor black box switch-mode-power-supply" that is supposed to supply raw 12v-14v dc to the monitor? This symptom is typical of lcd monitor power supply failure, and or inverter board failure. Not to mention the fact that the CCFT's could be a bit tired from use. YOUTUBE has some videos on taking apart lcd monitors. also do search on web for "bad caps on lcd boards" or "bad caps in lcd monitors". I should think that this Tatung might suffer from swollen cap-itis. get back to me with results of your investigation. Im louie12fix on fixya or just nrth of Windy City

Screen went almost completely dark, can barely see at all.

This is a hardware failure of the LCD back-light or a loose connection which requires partial disassembly to verify. Most likely it will require an LCD replacement. If you have an external monitor you can connect it to the video output so that you can see.

LCD's won't power up

The LCD not displaying a picture may just have a back-light issue. You can verify this by turning on the display, taking a flashlight and pointing it at the LCD then looking at the area that is illuminated on an angle and up close (1" - 2"). If the picture is visible then it is a back-light. You either need an LCD back-light inverter or the back-light itself.

LCD monitor does not light up, and consequently, does not display any image (as some other digital cameras do) during the aiming and focusing processes - sort of prescanning the image - before the shutter...

to my knowledge digital slrs aren't supposed to show you the image on the screen before you shoot because the battery would get used up too quickly this is what the viewfinder is for and the lcd is purely there to tell you info on what the settings are and to view your pics after shooting, I have the 400d and its the same for that.Hope this helps
