Old HDTV - component inputs not working

Post by D_Ames »

I'm a newbee here and I have an older (2001 I believe) Mitsubishi 1080 HDTV, model # WS-55819. It has 3 component connections. Two support 480i and 480p and both of those work just fine for cable TV or a DVD player . The third supports 480i, 480p, and 1080i. Mitsubishi calls this a DTV component connection. I tried connecting my DVD player (to get 480i/480p), my HD cable box (to get 480i/480p or 1080i) and all I get is a green or gray stripe down the middle of the screen. Sometimes the TV just shuts off by itself when I have something connected to the DTV component connection. The cable installer said it must be a problem with the TV but he didn't seem very knowlegeable. I have the TV's input assignment under DTV set to Y/PR/PB but that didn't help. The cable box scans the inputs when connected and tells me my TV is not capable of 1080i, even though it says 1080i right on the component input.

Anybody have any sugestions?

Thanks.

That is Mitsubishi at their peak in performance! Heck of a set when ISF calibrated!

Can you get your DVD player to work on the component inputs, any one of them?

I agree, 480p from my DVD player looks awesome.

No, I can't get anything to work on the DTV input but the other two component inputs (which are rated at 4801/480p only) work just fine with either my DVD player or my digital cable box. In fact, the only input that doesn't work at all is the 1080i DTV input.

Thanks

So if you hook up your DVD player to the DTV inputs it does not work? Do that and try setting the DTV input for either RGB or YPbPr... this thing can also auto detect and not so good causing problems... it does sound like it is stuck in RGBHV mode. Get the DVD player working and once it does then you should be set for 1080i.

Let me know if you are still stuck...

Thank you very much Richard. Let me try that and I'll get back to you pronto. I did connect my DVD player but I didn't change the input settings. Also, the TV turned off by itself when I connected the DVD player. For the next 10 minutes or so, I couldn't turn the TV back on. I unplugged the TV, let it sit about 20 minutes, and it worked fine again.

Off to try your suggestion.....

Ok, I connected the DVD player and tried both RGB and YPbPr and I got sound out of the DTV both ways, but no picture. Just a green strip down the middle of the screen. I should tell you that in the 6 years I've had this TV I have never used the DTV connections, only the coax and the other two component connections so the TV could have been bad from the start, I don't know. We just recently got digital cable with HDTV so this is the first time I've tried to use it.

One other thing is, if I turn the input off, the sound stops so at least I know the menu is controlling the input.

Any other suggestions?

Thanks

P.S. the TV turning off by itself thing, didn't happen this time. Not sure what caused that the first time.

Which resolutions have you tried into the DTV input?

My DVD player outputs 480i and 480p and my cable box outputs 1080i but I can't get that signal because the auto detect says it's not connected to an HDTV.



I'm also back to the TV turning off by itself. I turn it on, it stays on for about 5 seconds, then turns off. If I let it sit for a while, it will work again.

Let's start with the box. This is an analog connection you are using so there is no way the box will ever know what your TV does unless you tell it. This type of capability requires a digital video connection, DVI/HDMI, which your TV does not have. What box do you have?

I own this TV... What you are describing does not match how this TV responds to incorrect settings of RGB/YPbPr either. That is all about color and video levels; you still get an image.

The fact that you can't get your DVD player to work on this input yet it does on the others sure points to a defect of the TV. While that would not seem to make sense this input is unique in that it accepts both RGB and component and that puts it on a different circuit than the rest of the inputs. While you may use the same RGB wires the signals are two different animals.

I think it is time to call service. When fixed your DVD will work but you'll still have to figure out what is up with that wacky cable box.

So what your saying is the cable box won't be able to auto detect because the DTV input is analog on the TV? You would think the installer (ATT Uverse) would know these things.

When I get home today I'll find out what kind of box I have. When the TV input is fixed will I still be able to get HD from the cable box? Is it worth fixing the TV or should I just buy a new LCD with an HDMI connection?

Thank you again for your help.
