Title: Emax showing weird characters in LCD. Post by: 12bit on April 19, 2012, 11:50:08 PM Hi all.
My aging Emax is showing some weird characters. Sometimes it is at start up, sometimes it comes after a while. The machine is working as it should even though it is a little hard to navigate through the menus. Some days ago I took out the E-Chip and reseated it. It seemed to work, but now the problem is back. I am not sure if it IS the E-chip that is controlling the LCD, but if it isn't can some of you lead me in the right direction here ? Have a wonderful day; Kenneth.

Help ! Thanks. Title: Re: Emax showing weird characters in LCD. Post by: Alan EIII on May 08, 2012, 01:17:18 AM It gets to the lcd but usualy this is PSU related.
Lcd is just a side effect of the board system not properly powered.(panel buttons have no effect) First verify the psu connector(clean them) I don't know if the psu has to be calibrated like the one on the EIII but it also could be a good way to fix.(you could also do a recap job on the psu.) I have 2 emax II one i behaving like yours the other one is perfect and can be left powered for a long time without a problem. the one that have the problem come from a wet environement the other one has been babycared. On the one that has the lcd issue I can hear a little whitle noise coming from the psu - it gets louder the longer it stays powered.(and then it happens) Title: Re: Emax showing weird characters in LCD.

New here, this is my first post! i have exactly the same problem. it does seem related to the PSU, i'm trying to recap it but i can't find the value of some of the ceramic cap on it. those are the ones: http://img88.imageshack.us/img88/3565/img2012071700242.jpg and http://img684.imageshack.us/img684/9669/lehavre2012071000230.jpg Also i don't understand what it being referred as the "CS PAL" in the trim and diagnostic manual, page 9 problem: No Boot -> Bad CS PAL -> Replace CS PAL cheers Krikor Title: Re: Emax showing weird characters in LCD.

Now,some time the Emax will boot with those weird characters or bad display... it may turn good after it's on for a few hours but than when I get to do some work it will display those characters again... So,did anyone find a solution to this ? Thanks. Title: Re: Emax showing weird characters in LCD.

but be extra cautious when you do it! you need a good chip extractor. |
