hdmi pink screen

I've been using my apple tv fine on my sony tv (sony 37ex403 (i think) but i moved my apple tv to another sony tv downstairs (sony 37s5500) and now and again the screen goes pink. I've looked on apple site and it seems a common problem with phillips tvs and some sony. Just wondering if anyone else experioenced this or have sorted the issue. both apple and tv manufactureres blame each other (no suprise). hopefully apple will sort this in ios 4.3 but will then need someone to jailbreak that before can use it properly
