SOURCE: TV will not power on

The MZ73L is a posistor, its basically 2 thermal resistors back to back. One is connected across the mains, the other one connects the deguassing loop to the mains. When the TV is 1st turned on the mains connected R is cold so its neighbour is cold, that allows a large surge of current into the degaussing coil. The mains connected one rapidly gets hot and heats up the other one, this increases the resistance of it and the current being dumped into the degauss coil fades away. As the 1st one is a heater it will get hot and you will see signs of heat on the PCB, BUT its still a very good place to start. The heat is normal, but if the 1st ceramic disk in it has died then you will short the mains and blow the fuse with it.

I have a Durabrand tv. Model DWT 1304A. How do I get my Dish network to work on it. What do I set my tv. and how do i do it. Thank You

I hope that you have gotten this resolved, but if not, here are some steps to get that working!! I hope this helps!

If you are at TV1, where the receiver box is located, the tv needs to be on channel 3 or 4. Depending on the cable that is running between the receiver and the tv, the tv may need to be on an input, such as video 1 or 2. If you are at the TV2 location, where there is no receiver, then the tv needs to be on channel 60 or 73.
If you are using an HDMI cable, then the TV will need to be on an HDMI input
If you are using Component cables, your TV will need to be on a component input. (Usually Comp 1 or 2)
If you are using RCA cables, then the TV will need to be on a VIDEO input (Usually Video 1 or 2)
If you are using COAX cables, then the tv needs to be on channel 3 or 4 (If you are at TV2, then the TV needs to be on channel 60 or 73)

I just got cable today and need the code to the remote my tv is sanyo

I assume you want the code for the service adjustments which is to hold the Menu button on the TV down then plug in the set and service menu comes up.

If you need a code for a cable box for a sanyo remote check your users manual or i need more info about the cable box.

If you need a code for the sanyo for a 3rd party remote control you need to specify the remote. Or check its users manual.,

TV will not power on

You will need to acquire the service and parts manual. This will guide you to the correct part number(s) you'll want to order. Any reputable parts dealer can help you in that aspect.
What usually causes these types of problems is a failure of the device itself or a "chain reaction" sort of event, causing the visibly defective part to smoke through no fault of it's own. Be sure to check for proper voltages before condemning the wrong area. Hope this helps...Accordianman
