I had display problem of line 1 characters. lower pixels displaying lighter color. I changed the batteries. For a while it worked normal; and now the main row display, 3rd digit (from right) character is incomplete; like if number 5 is in that position, the 5 appears without upper hyphen or this - line. If this cannot be repaired I am ready to throw it away. vkmarko

Unable to locate a manual for this specific model, but if you go to http://www.sharp.ca/manuals/, you will find one for an EL2630-P, PII, and PIII. The functions are very similar and should give you the detail that you need. Generally there will be a reset button (likely on the bottom of the machine), which often must be pushed in using a ballpoint pen or similar implement, if no other routine clear or reset procedure (such as turning off and back on) is working.
Please post back if you need more help, otherwise thank you for using and rating FixYa!

SOURCE: The calculator is intermittent: Most of the time
Not knowing what to do, I tried anything that could possibly help:
I installed fresh batteries and I pushed the reset button on the back of the calculator (Sharp EL-546L) and finally, it work all right after more than 5 years I own the calculator and where it did work correctly for 5 minutes. I tried the reset button in the past (long time ago) and it didn't work. This time it worked because, maybe, I've used fresh batteries.

Hi, I had a similar problem and fixed it. Open the calculator and you will see that the ribbon connecting the LCD to the PCB has white and black stripes. The black stripes are the actual conductors. The white pieces are isolation between the conductors and serve the purpose of glueing the ribbon to the PCB.
Take a small flate screwdriver, its thickness has to be that of the white stripes. Heat up the end of the screwdriver with a hot air gun/lighter/hair blowdryer or whatever. Dont make it too hot. It should only be hot enough to melt the glue holding the ribbon to the PCB. Press the screwdriver on a white stripe and move the screwdriver up and down the white line which is on the PCB. Do this for each white stripe individually. Reheat the screwdirver if necessary, since there are a lot of tracks/stripes to cover.
It may be useful to use two screwdrivers: one to heat the glue of a white section and a second to cool/set the glue so that the ribbon is held in place, instead of coming loose because the glue is too hot. I did it only with one mildly hot screwdriver. It shouldn't be so hot that it actually burns you. You can test the temperature by pressing it against a hot melt glue stick (those used in a glue gun), if it melts the glue (but not too quick) it is hot enough.
It is unlikely that the ribbon came loose from the LCD, but if the previous didn't work you can try doing it on the LCD aswell.
Good luck!
