Do a reset to this TV and check. If it do not help you, contact any service technician. The main power supply regulator section circuit should be checked.
To make it a hard reset, just unplug the TV from AC mains wall socket, and re-plug it back after 15 minutes or so. This procedure will make it a hard reset. If you want to make it a system reset [Factory Reset]; you have to enter its service mode option, and select the factory reset option. 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/
Service mode entry, adjust and exit procedure to many popular brand TVs are given. Never forget to exit the service mode, after all adjustments have been done.

SOURCE: AOC Plasma TV turns on by itself and changes channels non stop.

I have an AOC 32" LCD HDTV and it turns on by itself as well. Tuning is done via my cable box, so the tv is set on HDMI and I don't have the channel changing issue. I as well am trying to figure it out. The only thing I could suggest is perhaps the remote batteries are low and triggering on it's own. Try changing the batteries, or ensure that the remove it in a drawer or other room so that triggering the unit is impossible. Hope that helps.

SOURCE: flat tv, sound but no picture. have tried

I had one that had a black screen and fixed the problem by repairing the inverter. When I opened the unit I looked at the capacitors on the inverter board and found them swollen. I looked at the bottom of the board and found that the fuse had opened up. The caps were a cheap quality low temp variety 150uF at 25V I replaced them with 330uF 25 volt 105C caps. I then replaced the 2.5A surface mount fuse with an axial 2.5A pico fuse and the TV worked beautifully.

My dynex tv only shows channel not available message?


Okay- the three cables (red, white, and yellow) are called RCA plug connectors. They are commonly used to carry audio and video signals.
Plug them into your Xbox according to the color codes- red cable connector to the red socket (jacks); then white to white, and yellow to yellow.
Now connect these leads to the RCA input jacks in the back of your t.v. - maintaining the same color code connections (red to red; white to white, and yellow to yellow)
The RCA input jacks on your t.v. should be labeled with an input number, to distinguish itself from the other inputs, like HDMI, S-Video, and such.
After plugging in your Xbox to the wall outlet or surge strip, turn it on.
Turn your t.v. set on.
With the remote control that came with your t.v. set, open the menu bar, scroll to... and open the "External Output" menu.
You should see a list of [however many] inputs your particular t.v has. Scroll to the input number that the 3 RCA cables are attached to, and press that number as the default video screen.
Exit the prompts and your Xbox video screen should be displayed.

I am trying to play a game on my playstation 2 hooked up to a Dynex TV but i can not find it on any channel or input. which channel/input would it be?


Make sure you do not have your PS2 plugged into an "Output" set of A/V slots. Change where you plug it in and scroll through your input channels to find it.

Godspeed,

Dynex tv works. bought ps3. when hooked up to


I would suggest you check if your PS3 is set up on going through the HDMI Cable.On your PS3's XMB scroll to settings -> Display Settings -> ANd from there go down to the one that says "Y Pb/Cb Pr/Cr Super-White (HDMI)" and hit X and select the option Yes... That sets the PS3 displaying through the HDMI
If you are already have done that I'm pretty sure you know you have to change the Input on your TV to HDMI... Take your remote and hit Input -> Scroll down to HDMI on the Input Source menu and hit Enter when you get to HDMI
If the AV on your PS3 works and not your HDMI sounds like Display Settings issue...
If you have done all that, that is strange if it still doesn't work.
There are some people that are having problems with the AV Cable with the PS3, I tried this and it really does work. I switched from HDMI on one tv to a AV Cable on another and when I did that neither TV would display content from my tv. The fix for this is resetting your PS3, like on a iDevice you hold the home button and lock button, for the PS3 you hold the Power off button and the Eject button for around 10 seconds. This resets your PS3 into default video settings. Until it Turns on, Beeps, and Turns off. This should work.

Channal selector down


Sounds like it is changing to another video mode that has no input so the screen is blue. On many tv's the channel buttons also act as video input button. This should happen with the buttons on the tv. If you are using the the remote I am not sure why it is acting like a video input button. Try changing video to tv with one and changing the stations with the other. I take it you are watching antenna tv and not using cable box or satellite. If this does not work and you have old vcr just use it as a tuner to change your channels.
