Update: I have another good working Toshiba HD here: model 42H83 / TAC0359. I did the same HD test with my sencore VP301 and my set does exactly the same. The viewable modes and the blank modes are the same, so this must be the nature of the beasts. I don't think anything is wrong with their set. They are on Dish Network sat service and maybe their sat box is the problem if any. Phil Bader Customer left a detailed description with the set. (last month we fixed it for "dead set" with pico fuse on power board+ resoldered converg. board,etc per Toshiba bulliten for when that F470 fuse goes) cust says: /"Flashes several times on 720. When picture came in it is white with a splash of color here and there. 420 and 1080i work fine. When formatting Res. change & flashes on pillar." /Read from that what you will... When I powered up this set here in shop it was set to "Colorstream mode HD1" Now... I have a sencore VP301 with the following HD modes, and I have noted here the effect I get on this set switching from one to the next (using the component video inputs): 480 i 29: good display with my Sencore VP301 on the HD inputs. 480 i 30: good 480 p 59:good 480 p 60: good 720 p 59: good 720 p 60: good 960 p 59: blank ("blank" usually means I see the horiz goes instantly out of freq then screen is black) 1080 i 25 blank 1080 i 29: good 1080 i 30: good 1080 p 50: blank 1080 p 59: blank 1080 p 60: blank 1080 p 24: blank 1080 s 24: blank I havn't yet gone all thru the cust. menu incase there is some setting causing this. Should this set display ALL these Sencore HD rates? Phil Bader // -- Philip Bader Jan Phyl TV Inc. (estab. 1976) 3420 Recker Hwy.
