I don't understand why this is under projection TV's myself. Maybe I missed something, but here goes the explination.

NiCad, or Nickel Cadmium batteries are really touchy with charging. Overcharging and undercharging really hurt their overall lifespan. Also, recharging with a partial charge left in the batteries can cause a decrease in life as well.

Best ways to maintain a Nickel Cadmium Cell is to follow the following instructions.

1 : Always make sure the first charge is as recommended by the manufacturer. Usually about 1.5 times as long as a normal charging cycle.

2 : Run the cells completely dead before attempting to recharge. This keeps the cells from having left over power and actually short charging.

3 : Never under or over charge these batteries. Always follow the exact instructions for the cells you're using. This will keep a high lifespan over the lifetime of the cell.


Now these batteries gain a memory in "lost charge" times. You can somewhat gain some time back by following those steps, however once they are shot; they are pretty much done. If they won't hold a charge for more than a few minutes, it's time to replace.

A good alternative however if you can change over to NiMH or Nickel Metal Hydride type batteries. These batteries have no memory and the cells will last through more charges then the elder NiCD style. These cells are much more reliable and can take a lot more abuse then NiCD.

I have a Toshiba model # 46XF550U Picture great. Sound decreases to 0 or sometimes goes to 100 all by itself. Must unplug it to turn it off, then when I plug it in it automatically turns on. ?


Sounds like main system control memory IC is faulty. anyway; try a hard reset to this set and check. If it do not help you, replace the memory IC. If you wish to get some details; check the site linked here. Pull up older posts. Surf the site with patience. http://electronicshelponline.blogspot.com/

I have just bought a Samsung LE -26R82B tv. After adjusting the Picture Standard for Contrast, Brightness, Sharpness and Colour the picture seems to revert to factory settings after about 30 mins. This...


Your TV is in shop mode which can be turned on and off by holding the front panel menu button down for 3 secs.

( Shop Mode is used to reset to default settings after 30 mins. and to not retain settings after power off.)

Turn sony w330 and upper left corner shows a battery replaced with a new battery and it still shows a battery in upper left corner help


After looking up Sony w330, I don't think that it is a projector, it's a camera? Might have posted in the wrong category? Nonetheless, here is my solution for the camera. Most cameras do display battery power to indicate how much battery is left in the camera. Some cameras give you an option to turn on/off the indicator because it may become annoying for some users as it could get in the way. The icon that you see may simply be a fully charged battery icon, unless you see some gap inside that icon which shows that the battery is discharging (being used).
If this has nothing to do with a camera, read below:
I have never heard of a projector that has a battery, nonetheless, I'm not very well knowledgeable with projectors, but my best educated guess from all of the devices I have used have experienced similar problems. You may have to execute a factory reset on the whole thing, and this might clear all memory of needing a battery.

Some channels have sound, others don't. Picture fine on all channels


Possible that the sound settings are in different modes on the TV. So check to set after selecting the channels to the required sound frequency of your service provider.
If not you will need to reset once again the memory and do a search scan IN the AUTO mode for resetting the TV channels.

Convergence goes out of adjustment every time you turn the tv off


Well you didn't list the make or model of your tv...
However it sounds as though your convergence adjustments are stored in volatile memory and the battery backup is dead. If that's the case you need to find the battery and replace it.

Have three colors in the picture after auto converge. how to reset the tv to factory setting


please tell us a little about your tv the make and model. their are far to many possibilities to list here without that. thanks.

in the meantime unplug the tv for several hours even a day or so.

Unplug the power cord for 5 to 6 hours then power it back up and see what happens if pressed for time. they claim that this will reset the tv but it's a jump into the unknown iff it has inetrnal battery. i bet it dosnt have that probably just a capacitor bank that keeps the factory codes in memory till caps bleed out. good luck with it.

No colour, contrast or volume memory. Channel memory OK, have fitted new battery.


Sounds like the eprom! I don,t have that manual in front of me but if it has a 8 pin eprom, try this, remove it and see if your settings are available and operational,( the ones in question) if they are then it is defective.

Reset...


Good Day, hdj2269808;
The best way to reset any electronic device is to unplug the power from it's source. Most A/C devices require at least 4 minutes; that includes: TV's, Cable Box, Sat Box, U-Verse Box and etc. Battery operated devices remove battery and re install; like cell phones and etc.
Good Luck, big IRISH.
