Sanyo lcd tv working great with computer

Computer Crashes TV?
for the last year and few months my Sanyo 26in lcd 720p has worked wonderful with my computer, connect thru pc port on tv hdmi computer connection with this tv is down right ugly.
issue
Out of the blue the screen would lock up and then go blank
it would come back, eventualy it goes blank and stays that way
have to power it down and leave it off for at min an hour

now if i am running this same tv with my dvr it never freezes or goes blank

if i am running my older 19in lcd monitor /w computer i have no issues I

Anyone have any idea what is happening here

Thanks In advance

Is the 19" monitor also connected via the HDMI?

both are connected via dvi to dsub on monitor and tv

having issue when connected to tv with either hdmi or pc(15pinDsub)

computer to hdmi on this tv has a horrable picture

Off hand , maybe a bad connector(s) on the TV? Where is the DVR connected? Try the PC on that one as a test.

attempted the hdmi that dvr is connected and it is still an issue
guess its just junk tv hmph
If you are planning to use tv with computer
I recomend not to Purchase Sanyo

Could be a bad TV. You might try a different HDMI cable PC>TV.

have you recently updated your display drivers?

as you state that when you run your dvr with the tv it works fine i would say the issue lies with the graphics card or drivers, once you've exhausted that side then look to the tv, don't go out and buy a new tv over this, at least not untill you are 100% certain of the fault.

on another note i've never found tv's to have a very good picture quality when the video source is a pc, it always seemed fuzzy and slightly out of focus, dvd's and normal tv is fine but stick a pc on there and they all of a sudden look terrible.

my best advice i can possibly give you? get a monitor for your pc and use your tv for well tv and stuff.
