HP 49G Display malfunction Message #1 Posted by Juan Viera (Uruguay) on 12 Dec 2006, 4:25 p.m. Hi, I would like some help since HP does not provide me with a real response. A couple days ago I found that my HP was not working properly; the upper line in the display shows permanently the R-Shift, the alpha, the transmiting, the busy and the comm with external signs, all in black. When I press the R-Shift all those signs turn blue, and as I press again to disengage the R-Shift they all turn to black again. With the alpha sign the situation is similar, but in this case the R-Shift does not turn blue, (or it turn just a bit). I tried the 1.18 upgrade, I tried the reset, I tried HP.com, I visited a couple of forums and I could not solve this problem. I hope I explained myself clearly in my rusty english. Thank You.

Re: HP 49G Display malfunction Message #2 Posted by Gene on 12 Dec 2006, 4:48 p.m., in response to message #1 by Juan Viera (Uruguay) It is always possible that your 49g may be on the way to dying. Sadly, electronics do that from time to time. Had a laptop, brand new one, smoke on me the other day. Display backlight burned out. Now in the old days, things just didn't do that! :-) So, your options are these given the fact that the 49g is out of warranty: 1) Live with the line of annunciators looking black or 2) Throw away the 49g and buy a new 50g. Sorry!

Re: HP 49G Display malfunction Message #3 Posted by Randy on 13 Dec 2006, 8:30 a.m., in response to message #1 by Juan Viera (Uruguay) The problem is typically caused by: 1) A defective LCD (~80% chance) 2) A mis-aligned LCD to logic board connection (~20% chance) IMO, replacement is probably your best option.
