HDMI output problem

[thehig]

I had my PC set up to duplicate displays, 1 to my monitor and a hdmi cable to my TV.
Randomly tonight the TV will no longer display anything, despite no settings or anything being changed.

Tried the obvoius, different HDMI cable, graphics drivers, HDMI socket (it plays the 360 in Hdmi fine).

I tried booting in safe mode, that kind of works, the PC monitor displays safe mode normally, but the TV displays it with a green background (instead of black) and just very noticeable the graphics are awful.

Changing resolutions does not do anything, It displays on nothing apart from 800x600 in safe mode with poor qaulity.

I'm out of ideas can anyone help.

Ps - My TV is an Orion 42" Plasma (old and dated I know, still does the job supports up to 1080i, 60hz refresh rate and max resolution of 1920x 1080.
Graphcs card is ATI Radeon HD 5450.

Is your PC detecting the TV as a display? Check it by going into Screen Resolution or Device manager.

yeah, sees it as Tv too, so in the AMD Vision software you can play with its HDTV settings.
On Screen resolution there are 2 monitors, Orion and My PC's monitor.

Connect your HDMI cable from your PC to another display device and see if it works. It might be a port issue. Just plug it into your monitor if it has a HDMI port.

okay done more investigation, I've narrowed it down to the HDMI port on my TV is faulty ?

Is it expensive to repair this kind of fault, or is it new TV time

If you know what you're doing, it could be as cheap as $10/£8. I'm not too sure how you would go about getting it fixed. Contact the manufacturer and see what advice they can offer you. Otherwise, just get a new TV 😛

I am not sure how you narrowed it down to the input on the TV but I have a thought if you have not tried this:

You said that the TV supported 1080i, not 1080p. Have you checked your driver software to ensure that your output is conducive to that resolution? In my research people have been successful with 1980x1080 resolution at 30 htz.

Just a thought

No hdmi devices work on the tv anymore.....also my pc works fine another tv set at 720p....its the hdmi port

Makes sense to me! I just wanted to be helpful in case it was a resolution issue. Is there no other inputs to save you from buying a new TV?

no just hdmi and component, the TV is old and needs updating anyway, I would get it repaired but the tv is upstairs and too bloody heavy to get out the house ha ha
