My Panasonic TX-29A3 is showing black instead of red after eleven years of trouble free viewing and not being repairable I am endeavouring to acquaint myself with what would be a suitable replacement in due course. I have in mind a plasma, but someone said that "Plasma and LCD have major flaws and are yesterdays technology. OLED and SED are where its going". Any views would be appreciated. Thanks, Emrys Davies.
