2 problems- 1-gasket is hanging loose on top of protection screen. 2- TV goes blank and I lose the picture and sound only on some channels at 9:00pm every night
I don't know how to get the protective screen off so I can re-affix the gasket. Also,I don't know if it's cable or the TV that's causing the screen to go blank (no picture, no sound) for about 1 minute every night at 9:00pm. It only happens on certain channels (maybe 6 channels) and only if I happen to be watching those channels at 9:00pm. If I'm on any channels other than these, it doesn't happen.
Unscrew the screws along the sides and top at back. gently lower screen forward and look inside--you should see the gasket--reattach it or remove it...I just removed it after staring at it for a year or more

If your LCD TV or monitor has stopped working, or is displaying one of the following symptoms, then it's a candidate for some new capacitors
- Flickering screen
- Screen image disappears after several seconds
- Dim screen
- Slow start
- Power LED on, but no picture
- Unusual colors and/or lines
The primary cause of LCD TV and monitor failure is caused by faulty capacitors. You can examine the capacitors in your LCD TV or monitor and actually see if they are bad.
If they appear bulged on top, then they need to be replaced.
New capacitors will solve a host of problems in LCD monitors and TV's and will extend the life of your monitor or TV by several years.
Check the cables, connectors and connections.
Take it to a repair shop.
This sounds like a common problem on these TVs (it's happened to both of my AOC TVs a couple times). Try a factory reset:
1. Press and hold "Menu" and "Channel+" on the TV. (do not use the remote) 2. Using the other hand, press the Power button. 3. A small screen should appear in the top left part of the screen. 4. Using the remote, select "Memory Recall" and Enter. 5. Power off and reboot the TV and Computer. 6. Run channel auto-scan to regain the picture.

This model is equipped with a self-diagnosis feature to help with diagnosis of shutdown problems. To activate this turn the unit on let it shutdown then press the input/device and menu buttons on the front panel simultaneously and hold them in for 5 seconds after 5 seconds the power LED on the front panel will blink a two digit sequence. This will be one set of blinks a short pause then another set of blinks, this will repeat 5 times. 1 - 2 = no error detected 2 - 1 = X-ray protect (high voltage or beam current) 2 - 2 = Short protect (short protect monitors low voltage supplies) 2 - 3 = Deflection protect (this could be loss of vertical or horizontal deflection) 2 - 4 = Vertical protect (usually loss of vertical from the source.
It worked fine yesterday. Sound on all channels. Sometimes the picture goes black on channel 6. We can get it back by going up one channel, then back to 6.
it is due to cable signal ie weak.
now there is no sound
this is due to sound section
1 loose connect in sound section
3 problem in sound section some part must have failed.
