black bars in pillar box mode uneven???

[rlgold88]

Are your bars on the side wavy? is that how they look on the hr20-700 and 100. I dont notice it to much on my sony 60 inch hi def tv using hdmi. But really noticable on the 30 inch samsung hi def tv using component. Does the wavyness or curves in the edge of the picture caused by the tv, display type, connections, or the hr20?

No, it's not a "feature" of the HR20. It sure sounds like some sort of RF interference to me. You might try a different set of component cables to the Samsung. Is there anything near the component cable that could be causing it? Other than that, maybe something wrong with the TV??

I don't see it on my Sony. Could be the vertical linearity is off on the CRT. My daughter had her HR20 on a Proscan CRT (my retired set) and I saw a hint of it. This does not rule out the HR20 though. I can't imagine cables to be the problem.

I can't imagine cables to be the problem.

A bad analog cable with a short in the shield (otherwise known as an antenna) can certainly cause problems like the OP described. But here is the critical question:

Do the waves move up or down on the screen, or are they static? If they move, it is indicative of RF interference. If they are static, then it is likely something else.

I always thought analog was composite/s-video only.

Y'PbPr analog component video (http://en.wikipedia.org/wiki/Component_video) is also analog, and susceptible to all the same issues as composite/s-video or any other analog connection.

Thanks Cygnusloop, always appreciate the info.

I would describe it as curves moving slightly with the picture and curves at the top in to the picture. I do see it on the sony but its not as noticable.
Could this be part of a grounding problem hum I have been troublehooting in another forum http://www.dbstalk.com/showthread.php?p=1035311#post1035311. forum is called grounding question.
I am not sure if this is connected but could it be????

[rlgold88]

how could i tell if its a bad cable (by apperance they look fine) ?? Also if radio freq problem could it be from other component connected to the tv ie vcr dvd.

Or is this part of a ground problem I stated above.
Totally confused

With cables, it is sometimes tough to see visible problems. You'll probably just need to try a different cable.

Is it possible to connect via HDMI just to test?

The 30 inch samsung only has component. Are your black bars perfectly verticle with no waves or curves.

Also to add on both tv's about one inch from the black bars I have a rainbow effect Vertically. Noticiable when looking directly at that area I dont notice it anywhere eles on either TV. Is that just a sd problem on a hd tv? Hd looks good.

My TV is a Samsung DLP, and my pillars are very straight, (except for the tiniest amount of pincushion). I'm not sure what you mean by "rainbow effect". When using the HR20 in pillarbox mode, you will often see stuff in the gutter of the frame, as the HR20's pillars don't include any overscan. So, maybe what you are seeing there is just stuff that is part of the SD frame.

Here is something to try:

Set the HR20 to native=on, 480p and 720p selected in the resolutions tab, and the HR20 to format=stretch mode. Then, tune to a SD channel, and set the Samsung to 4:3 mode. In this case, the Samsung will be generating the pillarbars, and we can see if they are straight or not. This should tell you if the problem is originating with the HR20/cables, or with the TV.

As for the ground problem causing this, I suppose it's possible. Grounding problems can cause all kinds of wacky symptoms, particularly when analog cabling is involved.
