We installed 4 PL5060N HP TVs into a lounge that we are doing the AV for.
Here is a single TV's connectivity:
From the Pace cable box we wire the component out to a MuxLab (component to cat5e video balun Part #: 500050). The cat5e runs (all runs less than 100 ft.) to an identical MuxLab (component to cat5e video balun) on the TVs end. We then wire the component output of the MuxLab to the TV's component input.
Everything works fine until the TV's picture randomly starts having a problem where a horizontal band (about 1/8th of the picture's height and just below center) starts jumping left and right like it is out of sync.
I'm trying to diagnose the problem to see which of these 3 components is causing the problem:
- Cable box
- MuxLabs
- TV
All these actions will fix the problem independently:
- Turn on and off the cable box
- Unplug the cat5e from either of the MuxLabs and plug back in
- Turn the TV completely off and force the TV to reinitialize (Simply forcing the TV into hibernate mode and back on does not fix the problem)
- Use the TVs remote to switch to a different source and then back to the original source.
It appears to me that any action which forces the TV to resync with the video signal will fix the problem. This assumes that when the TV goes into and out of hibernate mode that there is no resyncing of the video signal.
From the above info, my intial thoughts are that the TV is the problem. However, this is occuring on 3 of the 4 TVs we put into the lounge, which makes me reconsider the source of the problem because what are the chances that 3 of the 4 TVs are bad. The 4th TV may also be experiencing the problem because we haven't been running it as much.
Sometimes the TVs will go all day without exhibiting the problem. Other times our above fixes will work for about 10 minutes and then we see the problem again.
Obviously from my description above, I am not a AV expert so any suggestions would be great.
Thanks,
Holt
