it appears i have a problem with my new st50 55" and 24P.
when i set my pansonic blu-ray player to output 24P I get flashes and color flashes. happens between 5 and 30 times per movie, bluray only, audio is unaffected. flashes last maybe a second. raiders of the lost ark had a lot. the dark knight rises had only a few. I tried a different cable, no help. I tried running direct to the tv instead through my avr, no help. when I turn off 24P all is well.
do I even need 24P?
Is it worth the trouble of exchanging the tv?
I know you said you tried a different cable but was it the same brand, make, specification as your current cable? I would make sure you are using a good "high speed" HDMI cable. When I say "good" I don't necessarily mean expensive. Monoprice cables are reasonably priced and I have used many of their high speed HDMI cables with good success. The interference in the image you show looks like a symptom of a bad or incapable cable. I'm just guessing here and it's a cheap fix if that's the case.
