The HDMI doesn't work properly


HI

The resolution is only set by the sending unit, in your case the cable box. You need to change this to at least 720P something the your TV can handle.

Now once you have down this, to try and solve your HDMI problem I suggest you do the following.

Switch-off your cable box and the TV set, unhook the HDMI cable.

Now reinsert it carefully to make sure it connects properly on both sides.

Now first switch on your TV and set the input to Video 6 ( your HDMI channel )

Now wait for 30 secs. Switching on your cable box.

Do not press anything and check if your picture now stays on without shut-down.

if the menu and other startup screens on the cable box is not flickering, but the normal picture you might have a HDMI conflict with your TV set.

O, you cannot change the input types.

Hope this helps!

Toshiba 52Hm85 shuts down after 40 minutes & goes on and off


Only a few things could make the picture freeze and shut down. I would recommend checking the DVI cable that goes between the Chassis and Optical Block to make sure it is secure and tight. If it is (and it probably is), most likely it is the Optical Block causing the problem.Because of the cost involved, I would have a Professional to come out and diagnose it to be sure.
I hope this helps,

2 PROBLEMS


Your two problems are different . Your tv shutting down is not due to the tuners . First thing i would check is to unplug set and take the back off . On the left side is the board with your tuner on it . Look on that board to see if these is any liquid buildup on it. One of your picture tubes could be leaking causing set to shut down . This can also be causing your snowy picture problem as the liquid has started to spread . The metal braket above this board is where the liquid starts to trickle down from . Use a flashlight to see . If you see no liquid then you have hv sweep problem which would need to be checked out. If you still want to get a board www.ptscorp.com May have your board in stock . Good luck

Unplug the three red-blue-green plugs nest to the convergence amps. If the unit powers up and stays on the picture will look bad but will confirm that the convergence amps have failed...
Replacing the amps and one or more resistors in the yoke return will restore the set to normal operation..
Use only Sanyo original Ics..
