Its possiable that you may have poor solder connections where our STK ICs are resolder them and transistors they are big black ICs will have STK392-110 on them. I would First start out with soldering everything on convergence Board.

If the picture on your TV flickers, there may be a simple fix. Here are some possible answers and suggested solutions:

1. Your set-top box may need a simple reboot. Unplug the power connection to the set-top box for about 30 seconds. Reconnect the power and turn the set-top box back on.

2. Check all of your cables for a loose connection by tightening each one with your fingers.Flickers can sometimes be caused by bends in rigid cables, too.

3. If your picture flickers to a black or blue screen, you could have a bad set-top box. Contact your cable or satellite service provider about installing a new one.

4. If you still have audio, the flickering could also mean that you have a failing backlight.

For additional troubleshooting information, check out the chart at TV flickering for more solutions. I hope this helps!

I have a HDMI cable hooked between my Direct tv DVR receiver and my Samsung flat screen HD plasma tv. When I turn to Direct tv channels 100 or 200 the screen begins to flicker. My tv is 1080i. This is what...


If the TV just Flickers for a few Seconds then the Picture is Good and Stable, That is just the HDMI re-syncing often due to different signals from 480i to 1080i being broadcasted. If it continues to Flicker then check the options for Video set-up in your DTV menu. Make sure all available resolutions are checked to display or select AUTO if possible. TIP: NEVER Unplug or Plug in HDMI cables with the Power ON. This can Short out the HDMI Input leading to a Repair. Turn off All Units then plug in your cables, When ALL are in then hit the Powers.

Screen flickers on / off when run through receiver


No solution, but I have the same problem with my Panasonic plamsa TH-50PE700U with a Yamaha RX-V2700 receiver. I don't think the cables are a problem. If I turn the TV on and off about 20 times the system stabilizes until I turn it off.
