Tv won't power up straight away


when lcd tv`s fail to power up, but stay on standby. It is usually because of bad capacitors on the power board. My 22" lcd monitor did the same. It would not come off of standby. It starts with them being slow to turn on. "Sound familiar"? I fixed mine by changing the bad caps. There were two of them.

I have a Dynex, model DX-L22-10A . The problem is that the picture is in the middle of the screen.


Try changing the size of the screen by pressing Ratio or Screen size using your remote.

My remote is not working the tv. I have changed the batteries,


Hello,The first thing to do is to check to see if the problem is with the remote or the TV. You can check to see if the remote is sending a signal. The easiest way to do this is to take a digital camera or a cell phone with a built in camera. Point the camera at the top of the remote and press then press any key on the remote control. If the remote is sending a signal you'll see through the phone or camera screen a light illuminate on the top of the remote. If you see this light then the problem is with the TV. If you don't see this light you will most likely need to replace the remote with a universal remote or provide a model number to see if an original is available.

My LG HD tv screen suddenly went green. sound is


Hi,
I disagree with info provided, if screen of your LG lcd tv becomes green that means inverter board is working and lcd tv does not have convergence ICs.
Please unplug tv from ac wall socket for minute to get it reset, replug back in and turn it On and check its picture.
If still showing green screen then change input source with remote, if tv shows same green screen on all inputs that means its either lcd panel problem or digital signal processor got bad loacted on main board. Local tv repairman is needed to confirm and fix it.
Thanks.

RC00070P remote has stopped working


Testing remote control:
The remote control puts out IR (InfraRed) signal that human eyes cannot see, to find out if the remote is sending out the signal or not you just point the remote at the digital camera’s Lens (Digital Camera can detect IR), you should see flashing light on the camera’s screen when any one of the remote button is pushed. If you do see the flashing on the camera, then the problem is in the TV IR receiver or the main logic board; more troubleshooting with scope will be needed to look at the signals.

You can get remote directly from Viewsonic, they are about $25 + shipping.

The remote control works sporadically and when the TV is turned on or is bumped, the menu and volume displays flash on and off on the screen. What can I do to fix it?


NO, your remote control sounds like it is sending the signals to the TV. Take the batteries out or put it in a drawer to test. If it's the TV doing it itself, then it's a bad remote receiver circuit.

HD TVs do have different cables, I went to Time Warner and swapped my regular box for an HD box, the cable ends are blue red and white, I believe. Also in order for my box to work on the screen I have to switch to "Component" instead of "TV". Hope I helped!
