The problem can be in the inverter board, look for open fuse, or worst will be bad lamp/lamps. You need to open it up and report back what you see so we can guide you furhter: see what bad lamps look like: http://s807.photobucket.com/home/budm/allalbums

I have a tec SL39N digital scale. When I plug it in the mumbers appear across .. 111111. 222222. 333333 etc. It goes to 9999 and then goes back to 88888and the 8's keep flashing. Help! Thank you.


Good Evening Paul, and Happy Holidays.

You can view the manual for your scale here:

https://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=1&ved=0ahUKEwil1tu6oeTJAhUG_mMKHRbRBMkQFggdMAA&url=http%3A%2F%2Fpdfstream.manualsonline.com%2F4%2F4249c7d6-8aca-4d71-82c7-2a6ad53f509b.pdf&usg=AFQjCNHFxSA5IvPtpNw0tHJgBjUjLNtxQg&sig2=yTmgL-Oxe95lCTHu4KY_Lg&cad=rja

It makes mention in several places about the scale displaying flashing 1111111 and flashing 8888888 displays, which fortunately appear to be signs of it turning on and saying 'ready'. Some of the display action appears to be affected by how long the gap is between when the scale is plugged in and when the power switch is turned on.

Hoping this helps!

POS X Evo TP1 A1N screen appears to be off, but power is on


first of all check your monitor. it would be the best if you can plug some other monitor just to check... if your monitor is OK then probably you VGA is bad and you`ll have to change it.

The display flashes on for a second or two, then goes black. This happens each time it gets a new type of signal. So for example when booting up the PC it displays the video card logo for a second, then...


Bad caps can look normal but can have high ESR, you also need to check the DC voltages. You can also have bad lamp assemblies, etc.
Make and model will help also, you can look for service manual here: www.elektrotanya.com

Monitor will flash the display for a second then go black again.


Most common failure in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed SAMSUNG monitors to get some ideas what to look for: http://s807.photobucket.com/home/budm/allalbums
Post back what you see inside so we can guide you further and it will help out other people in the future also.

Not really that tough. Sounds as though the backlight is shutting down, either from a power supply failure, or a failure of the backlight circuit itself. You can verify this by holding a flashlight to the screen in the area where the menu usually appears to see if it displayed on the LCD panel with no backlight. If you can faintly see the menu displayed, your backlight has shut down and the most likely cause is the backlight inverter board, followed by the power supply and the backlights themselves which are part of the LCD panel. If you found this information answered your questions, please be sure to rate it. Thanks!
