If you are bored, have nothing else to do, or want to force a memory overload reset from the comfort of your chair (using the remote); then for fun you can try this.
Please keep in mind there are no guarantees! Your Sony Box could catch on fire and never work again.
1. Turn box on and tune to any channel
2. Set Up a keyword search for the letter T (if you must you could use any letter).
3. Begin your search for programs with the letter T in them, and you should see one page of programs with a letter T in them
4. In order to overload the memory; begin paging down (channel button up/down - use the down of course) several times - you may have to go a few hundred or thousand programs down. Just hit the channel down button about every other second (perhaps ten times), soon the Sony Box will say on the front panel Welcome. It has now begun its reset process and will turn itself off. Do nothing until your clock comes back on with the correct time. This could take 10 minutes or a couple of days. If your area does not normally get a clock set quickly then you should not do this, or you could develop rabies.
Once your turn the box back on, confirm that your keyword search T is no longer set up in the box (this is how it worked for me - it may not work that way for you). If the keyword search T is still there, then Delete It Now! If you cannot delete it (unlikely), then you may have to do more aggressive resets to get rid of it; perhaps 9012 TVGOS reset -should do it, if not then maybe a Reset Factory Defaults. This could mean you would not be a happy person.
This type of Memory Overload Reset set should create an 800A reset that you will see on your Reset Error Tracker Page with the date/time stamp.
The 800A now has a definition Memory Overload Reset
