This is a common fault as the set on ageing deteriorates in the connections. There is a high possibility that the components over a period of heating and cooling, tend to bring on a problem of dry soldering. So my advice is to check the set for some loose joints that have played on to give you these erratic shut downs or poor performance.
The best way to check for loose connections is to tap lightly when the set is powered on , If there is change while tapping then it seems that there are DRY solder joints. Remove main plug, the covers - with caution of high voltage, check for dry joints, use a good soldering iron to solder all suspected points.
Sometimes the fault occurs when the set warms up, if so you can simulate the heat using a hair dryer on the suspected areas, try with the power supply, distribution, Processor controller, driver controllers on the A/V related sections. Also the use a FREEZE-IT spray can simulate the components to cool and show up the fault.
Based on the above method you must be able to locate the area of fault and solder the sections. Sometimes large IC's- ones with more pins- tend to have drying in some pins and so cause faults related to the IC's protocol. Have a rough idea of looking into the areas to reduce the time of probing.

We would be happy to help you with getting your new DISH Network remote to control your TV. We're going to start by pressing and holding the TV button located on the top of your remote until all mode button back lights come on, and then release. Use the number buttons to enter the codes for your Orion TV; here are some of the codes we currently have for it: 720, 748, 748, and 748. Press the pound (#) button. To check that the code works try several different functions on the remote to make sure it will properly operate the TV. Remember that some codes may not be compatible with your equipment. If this is the case, try the other codes listed for your Orion TV until you find one that is compatible with it.
We hope this helps and thank you for being a valued DISH Network customer!
