Pink Screen Problem on HDMI Cable (A Technical Note)

Tuesday, December 21, 2010

I recently experienced having a Pink Screen issue on my 40BX400 Sony LCD screen. This happened after I connected it to my workstation's ATI Radeon 4870 HD computer. Everything on screen was shown with a pinkish hue, at resolutions 720p and 1080p. Oddly enough, when I changed to a DVI-to-HDMI connection, this problem did not happen.

After looking around the net, the following possible reasons were brought up:

1. Cable is broken - not my case since I remember I was already able to make it work the other day when this happened.

2. Video card is broken - again not the case, since the DVI-to-HDMI cable option was working, albeit with a significantly lower refresh rate.

3. TV reads the video as a component input instead of an HDMI input - strange bug, considering that I saw this happens on a whole range of flat screen TVs from different manufacturers. However, due to the lack of a better lead, I have come to believe that this is the cause of my problem.

I was able to fix the problem by plugging unplugging the HDMI cable from the TV side a couple of times. I understand, however, that this is a very stupid solution that offers no real explanation as to why the pink screen happened in the first place.

However, I'm glad to see that it works. Try it on your box too if ever this problem comes up. And if you have a better idea as to how we can prevent this, I'm all eyes/ears/ports.

I think you have a bad time with your cable. Try another gold plated Hdmi cable.
