here is the owners manual / user guide . it says that in case of a power failure it supposed to retain memory indefinitely , since yours did not , maybe you should program in some channels , giving it some new memory . your question is listed under uniden model bc248clt , thats correct right ?

After a power outage of approximately 45 minutes i have no display


Hello
There is a Lithium battery inside your clock to get a backup even the power is interrupted for a long time. This battery may last up to 3 years eventhough there is no power to the device. If this has gone weak, the backup fucntion will not be. so check this battery.
Just reset the device. It will make it work properly. To reset the clock after total memory loss; do the folloing.

[1] Connect the radio to your AC outlet and let the clock set itself.

[2] Depress the MONTH/DATE and TIME buttons together. The display will change
from 'Time'to 'Year'

While holding the MONTH/DATE and TIME buttons, press the SET + button
to set the display to the correct Year, then release the buttons
OK.

The screen does not light


Plug an external monitor and reboot. If external display also no display, your lap mother board is gone. Else your graphic card on the motherboard is gone. Replace the relevant part

I have sharp er-a420 it was in my garage for two years. I like to reprogram my register. I think I need to reset my register, I do not know how. Manager?s key does not do anything. When I plug it in on the...


Most Sharp register, including the ER-A420, have a rechargeable battery mounted inside to hold all memory when the power goes out. It should last a few months, but two years is a bit much. This might get it going:
  1. Unplug from AC POWER.
  2. Turn the key to PGM.
  3. Hold down both paper feed keys (at top-left of keyboard).
  4. While holding those two buttons down, plug the power back in.
  5. Turn the key back to REG.
  6. Enter 1 CASH # to sign on as Cashier 1.
  7. Try a sale.
There is a strong chance this won't do the job, because the memory has been randomized by total loss of power when the battery died. Worse yet, the battery may be too far gone to ever take a solid charge again. If so, you probably need the help of a Sharp register dealer to replace the battery, totally clear all memory and reprogram it. It's probably worth the money; the -420 is an excellent little register.

I have a 3 year old Toshiba Tecra M4 Tablet Laptop, and my colors are inverted, anything that should come up black, comes up red. Text is okay, but images just don't look right


It would be oen of three things... in order of cost;

1. LCD Invertor has gone bad
2. SCREEN has gone bad
3. Motherboard has gone bad

In either of the three it would most likely take a toshiba tech to pinpoint exactly the problem and do the repair. Although if you are handy enough you can get the parts and repair it yourself.

Internal memory card reader plug on the MB?


The memory card reader that you have is most likely running on USB, therefore you will need to plug it in to one of the USB headers on your motherboard. They usually are made for 2 USB ports so the connector for USB is 2 rows, but yours is just flat so it will fit anyway.
The USB plug and cable on the motherboard kind of look like this:

Pc starts and runs but wont boot up monitor shows no signal


1) When you turn on the computer, watch and listen for:

a) power supply fan, (power is on)
b) chassis lights (power is on)
c) ticking sound during memory test
(the BIOS POST is running)

d) beeps or rhythmical error codes
(POST failed, bad CPU, CHIP set, memory or video)

e) Monitor either comes on, displays garbled video,
displays a No Sync or No Signal message...

No depending on how far it gets:

Check power supply, cables etc.
Check video cable.
Check monitor with a different PC

Now unplug the power cord, with the computer still
on, this will help drain any internal capacitors.
Wait 5 minutes, then shut off the switches,
and open up the box. try the following,
one at a time:

2) Remove all I/O cards except the video card,
and don't plug them back in until the problem
is fixed. Unplug all the ribbon cables from
the mother board as well:

Hard drives, CD drive, floppies etc.

Make sure you make notes about how to plug it
back in, and cable orientation !!!

0) Re-seat all power cables: Red, Black Yellow harnesses.

1) Unplug and re-seat the video card

2) Similarly, re-seat all memory SIM/DIM modules,

3) Re-seat the CPU

4) Replace the video card

5) Replace memory, CPU or whole mother board,

Plug the good parts back in one at a time,
and test the machine.

Save for the power supply, there really is NO way to test
and isolate a bad module except by swapping/ trial and error
because of inter-dependencies.

For example a bad I/O card, any I/O card, can short circuit
the I/O bus, causing all other plug-in cards to stop working,
or even the main mother-board to freeze during the POST.

A bad power supply ditto.

A bad memory chip ... ditto.

The type of electronic instruments required to actually
test modern computers running at Gigahertz speed cost
hundreds of thousands of dollars, some cost millions, and
are only available to hi end manufacturers

Even the power supply will not power up for a voltage check
if the mother board is bad, although you can use a jumper
on the green wire to ground to force it on, when you unplug
the power connector from the mother-board, if you are brave.

Computer shops carry a lot of spare parts, and their service
department has gutted computers rigged up as test jigs.

They trouble shoot your system by either plugging your
stuff into their jigs, one at a time, or by plugging known
good components into your computer until the problem
is fixed.

This if of course possibly dangerous, since one bad part
can also fry other good parts that plug into it, or that it
plugs into. The compute shops, of course charge you
enough to make up for this.

If a computer is partially operable, it is also possible to
run software diagnostics.

If not, swap and pray is the only way.

Hope this helps
