The TV has 4 hdmi ports, however after a while one of them stopped working properly, ie I got 'noise' on the screen, a bit like lines of 'glitter' across the screen. Anyway I switched to a second port and that seemed to work fine.for a while, then that too developed the same kind of problem. Anyway I try a third port and that works fine. However I am getting worried now because I have only had the TV about 3 months and the ports seem to only last a about a month and a half. I connect a cable to the port almost every day and disconnect it after, so the port sees a lot of 'action' and I am wondering if I have damaged it. It seems a delicate connection consideing the size and weight of the cable, the metal contacts/threads look about a millimetre of less wide, easy to damage I would imagine. Anyway I have a look at the ports and they appear fine as far as I can see (not very easy to see in though!!), however I notice on the cable one of the pins appears to be short. According to this image it is a +5 volt pin http://www.honline.com/open/imgs/45/3/7/0/8/2/6/a9c5472cf765c641.jpg However also note on the image the same pin seems to be short, as it does Re: Problem with HDMI connection. 1
Re: Problem with HDMI connection. here: http://www.blogcdn.com/hd.engadget.com/media/2008/04/41408lockinghdmi.jpg So I expect it is not needed. Actually that is disappointing as it appears to rule out a fault with the cable, which is easier to resolve. It woudl be handy if you could have a look at your cables and tell me if they all have this 'feature' (I only have one cable). It does however make sense it is not the cable, because othersewise it would not work in any socket, and it works in the two I have very rarely used.
It is this TV by the way: http://www.comet.co.uk/shopcomet/product/524565/HITACHIL32VP03U Maybe that is why it was so relatively cheap? It will be a real pain if I have to return it, however it looks like I will, should be no problem as it's only 3 months old. Also I expect a lot of other TV's will have the same problem as HDMI has a lot of delicate connections going to it. It also has a VGA connector so maybe I should get a VGA cable instead? Or I have been thinking of getting a short male to female connector and leaving it in the socket so it experience less stress. Any thought? Anyone had similar problems?
OK I tried connecting again and the TV died, no picture, an led light works and some of the buttons make noises but black screen and it won't rspond to the remote. Back for a refund!! DO you guys switch off TV and PC when connecting by HDMI?
