Not so sure there, but I have herd that some people put their RAM and or memory modules in the fridge or freezer for the night in a sealed plastic bag. The cold resets them, however you will most probably loose your information that is stored on it. Let it dry and rest at room temperature before you use it. You can also google this before you try it, I say it's always better to do some research before I try some-thing.

Hope this works for you.

I have a Sceptre Model X320BV-HD Serial # A51C3AC1AD6821 that recently started acting funny. Using a Mohu Leaf for an antenna and a Fire Stick for Amazon Prime.

Main system control memory IC fault. This is a very small IC; have 8 solder terminals, and can be located very near to the main system control-chroma IC. Check and replace it. Be sure to replace it with the same number printed on it; in all respect. Otherwise, it won't go.

This happens due to the faulty memory IC at the circuit board. Replacing it will solve the problem. It is an 8 solder terminal IC, can be located very near to the main system control IC. Will look like this.

Hi i haave 6500c,but it show white display.i change also new lcd but same problem pls tell me about this problem.

The numbers on the phone is not showing...or when somebody calling in

Did you mean there is no display, if so the display unit is having the fault . Open and check if the connecting lines are faulty, remove and reset, if not the display is faulty.
If thers is no caller identification on yourr phone(CLIP)/ or the memory is not showing any numbers, then it is possible that the sub controller IC/memory is defective.
Best to do is to open and solder this section for any moisture, sweat/water. Look for any clogging of dirt, clean ,touch up solder with care not to bridge any circuits.If this wont help the IC must be defective and it might not be very economical to change with the cost of a new one.
Hope you decide with this tip

My lacie electron blue 19" monitor image is reduced to thin horizontal white line. Is this monitor repairable?

If you can find a shop that works on TV sets they can probably get this going for you. The trouble is usually due to the solder connections going bad at the vertical output integrated circuit (IC). This is a common problem with TVs, and computer monitors are very similar in design. It's usually a quick fix with a soldering iron.

There's always the possibility that the IC or some other part has failed and is responsible, but the bad connections are so common that it would be a good place to start. Then, if that doesn't fix it, you can look for a replacement. Beyond the simple solder repair, anything else will be uneconomical.

The vertical circuit is malfunctioning. This can be as simple as poor solder connections at the vertical IC or a defective IC. If you can solder, you can fix this yourself. Please use caution as there are potentially dangerous high voltages present inside the set even when unplugged.

Locate the vertical IC, which is a small flat IC attached to a heatsink. It should have 9-11 pins and be karmed LA7833 or something similar. Resolder the pins first. If that does not resolve the problem, replace the IC (about $15-$20). It is possible that some of the capacitors in the circuit are also defective. If that is the case, the above actions will at least change the symptoms. Update this with any change other than complete resolution of the problem, and additional instructions will be supplied.

Format error in a new dsc-s780. Formatting the 8G card does not solve the problem

I am not sure that it accepts 8gb cards

but at least try this:-
If you have a computer with a memory card reader that takes the stick. insert it into the computer and goto my computer find the memory stick drive letter and format it there then retry the stick in the camera. if you cannot format the stick it is very possible it is bad.

I have a satellite P20 that does not start up. Power comes on but there is nothing on the screen. Everyonce in awhile it will go on and works great. But 9 out of 10 times I power it up and there is...

Had a similar problem with a Satellite P105. I flipped it over, took out one of the memory sticks (one screw to open the little memory door) and turned it on again and it worked. Then I took out the other one and put the first one in its place. Worked again. Then I moved that stick back into the first slot. And that's when I found that one memory slot was bad.

I have a beltronics 940 radar detector and when ever i turn it off and then back on again the volume turns all the way down and it won't save any of my settings

I don't know this particular model. I will comment genericaly.

Most of these devices have an internal memory battery. Some models use a gold leaf capacitor.

In some models the memory battery is on solder terminals. If you are experienced at using a soldering station and know about how to change components on a circuit board, you can change this type of battery yourself. You will have to open the unit to get the battery part number.

If the unit uses a socketed type battery, this is a lot easier to change.

If the unit uses a gold leaf capacitor, the old one would have to be un-soldered from the circuit board, and the new one soldered back in.

Once you have the specifications for the required gold leaf capacitor, or the required battery, you can probably get these from most electronic parts suppliers.

There is a chance however that this manufacture is using proprietory parts. Then you will be forced to order original parts.

Rarely, it is possible that the memory storage problem is a bad IC on the circuit board. If the IC is a SMD device, you may not be able to change it with conventional soldering tools. This will be manufacture service only.

If you are not familiar with the above, you should call the manufacture to find out how to have your unit serviced by them or an authorized service place located near to you.
