Where can i get the battery 7100 coby TF in fresno and do they have one ?
Have you already removed the battery? There will be information on it telling you which battery to use as a replacement. As a general rule I would suggest you Don't start taking things apart if you are not sure what you are doing! You could cause more problems than you're trying to fix. Ask at your local TV repair shops and even some of the computer repairers. They may be able to help you. You would have to ask them directly if they have one in stock but commonly if it isn't a commonly used battery they will have to order one in for you.
If you have the battery details you might be able to get one online.
How do I set up a cable box for the television please?
Follow the steps below to connect your cable box to your TV using an HDMI cable:
- Turn off your TV and cable box.
- Make sure the wall cable connects to the cable box.
- Connect the HDMI cable to the cable box port.
- Attach the cable's other end to the HDMI port on the back of your TV.

These LEDs are very susceptible to static electricity damage. What happens when they get zapped is a tiny threading fault starts in the LED crystal. The aluminum contact metal starts migrating into the crack, makes it wider and longer, and eventually goes all the way through the LED and shorts it out. When that happens, the metal overheats and burns out the LED so the entire string goes dead.
What this means for you is that the original LED may have been may have been zapped at the factory. The replacement strip likewise, or when it was removed from another TV (if it is a used part), or when you put it in. It should have been in anti-static packaging. You have to be very careful not to touch any of the circuitry on the LED strip, and make sure you ground your hand to the TV metal both before picking up the LED strip and right before connecting the strip to the TV. Better yet, use an anti-static wristband connected to the TV frame.
It is possible that the LED driver for that string is pushing too much current, but that's not likely. You would probably notice that part of the screen is unnaturally bright.

My Silo tv was playing good. I cut it off went to work . Cut it on no sound or picture. Screen is black .HELP
If the TV was made between 2002 and 2015, there may be a burned-out electrolytic capacitor in the power supply (sometimes several; my personal record is 13 in one TV set). These are usually obvious on visual inspection - the top of the capacitor can will be bulged outward instead of flat (the picture below shows a bad unit to the right of a good one - these are the black cylinders with printing on them; electrolytic capacitors may be different colors, but otherwise look much the same). Note: unplug the TV before removing the back cover. Don't touch the circuitry without grounding yourself to the metal frame; static electricity from your body can damage the TV. Don't touch the circuitry while the TV is plugged in, ever, especially not the power supply board.
The replacement part is under $2 (plus shipping and taxes) from an electronic components supplier. Don't look for the same brand of capacitor, select a part with the same capacitance (a number with µF next to it), the same or higher voltage, same lead spacing and physically sized to fit in the space available, rated for high frequency use, high ripple current and long life rating. I've had excellent results with Panasonic FR series parts. The smaller sizes are rated for at least 6000 hours at high temperature and the larger ones for 10,000 hours (they last much longer at lower temperature). Replacement requires soldering skill. Be very careful to put the - terminal in the same hole as the original - it's almost always marked on the circuit board. Putting the capacitor in backward will destroy it very quickly.
