Trying to get a picture through the component input by using a HDMI to Component converter on...

post #1 of 9

Hi,

I have a really old Sony KV-32XBR250 with a set of component inputs in the back. A Toshiba DVD player player is connected to the component port and I get a good picture quality.
I wanted to connect my WD media player to the component input by using a HDMI to component converter.
one of these:
http://www.amazon.com/CNE62300-Component-YPbPr-Stereo-Converter/dp/B00APEG9N8/ref=sr_1_10?ie=UTF8&qid=1366820393&sr=8-10&keywords=hdmi+to+component

But when I do that, I can not get a picture. it's just flickering lines, like scrambled channels.
I tried to connect my Samsung Galaxy S2 using a MHL adapter through the converter into the component. I think the TV output resolution on the phone is 720x480. and I get the same flickering lines.

another attemp to get a digital picture through my component inputs was trying my Philips Ipod docking station with component output cable with Ipod Nano 4th generation. Again flickering lines..

I thought this tv should be able to process 480p through the component input? or am I wrong?

Is there any way that I can change anysettings in the service menu to adjust something to get digital picture? or is it not possible at all?

should I try a HDMI to composite connector instead?

Anyhelp would be greatly appreciated..

thanks.

If they'll allow it, you need to set your source devices to output 480i signals.
Otherwise, you'll need to get a new TV. Sorry.

As best I can determine from its manual, your TV is a traditional standard definition NTSC device. There is no mention of any signal type. In other words, it can handle only a 480i signal. (262.5 scanlines per field, two fields per frame, 30 frames/second). It cannot handle either a progressive signal (like 480p) or a high resolution signal (like 1080i). Your description of the symptoms is consistent with sending it the wrong kind of signal.

I think the Ipod's TV out resolution is 320x240 or 640x480. Shouldn't the 480i TV be capable of processing that? isn't 480i 704x480 pixels?

Sounds like a HDCP issue to me.

Its still all part of the HDCP crap.

A CRT TV that's designed only for 480i can't handle 480p. This particular TV model (KV-32XBR250) is 480i only and is too old to have HDMI. HDCP is irrelevant.

It might be able to display a 320x240 video signal, but that depends on how sloppy the vertical sync circuitry is in the TV. Sony's XBR TVs were very well designed, so it probably won't work.

Traditional NTSC TV video is not at all like computer video. It was designed to make the best use of low bandwidth radio transmissions, taking shortcuts which are made possible by how the human eye works. In modern notation, the video signal is called 480i -- i = interlaced, and it actually has more than 480 scanlines per frame. Being interlaced means that half of the scanlines -- every other scanline, the odd numbered ones -- are transmitted during one field in the first 1/60 of a scond, and then the signal goes back up to the top of the screen and the other half of the scanlines, the even ones, are sent during the second 1/60 of a second. The human eye normally can't respond that fast, so it looks like you're getting the whole screen at once, but you aren't. In contrast, computers use progressive video (e.g. 480p). All "480" of the odd and even scanlines are drawn sequentially from the top to bottom of the screen each 1/60 of a second. (i put 480 in quotes because the actual number of scanlines is greater than that.)

thanks so much for your reply Selden Ball..

One last question I have.. do you think an HDMI to composite converter will work? I think the output on those converters are 480i.
thanks again.

An HDMI to composite converter should work fine. Composite video is always supposed to be interlaced.
