Polytron TV Protected

TV Polytron also sometimes have problems in its internal memory system (in series STVxxxx ic program.)
Symptoms are at the time of the restart, a few seconds will burn about 10-15 detik.Timbul voice for a while, after that protectionism / standby.
This is caused some errors in the data memory which the program contained in the IC.
To cope with this kind of thing, you just do tricks I will give the following:
Turn on the TV as usual, and wait for a position in a state protectionism tv / standby, use orsinilnya remote, press the menu button on the remote and stand for about 3-5 seconds until the TV lights up automatically.
Direct Tv Usually normal again, because the data in memory has been reset automatically to the state of PP (pactory presets).
Why can happen so? because if the TV position standby.tombol power switch command signal (ON) to the IC program.Kalau on standby, pressed the menu button and hold in a few seconds will give RESET input data memory (flash). And if the conditions of normal memory, then in a matter of 'timing' in a particular order will interpret as a signal into the MENU position SERVICE.Dan system will automatically ask for a passcode to enter the sub-menu service.
Its passcode code is 1013 for basic settings (features) and 1014 to regulate the main parameters (H-frequency, V-amp, AGC, AFC, etc.)
And if you get problems like who I mentioned above, this method is the most easy to previous mengatasinya.Tapi first make sure that all the solder points on the TV machine no problem, it helps you thoroughly before all the solder points earlier.
For what? because the protection system will also be reading the state of circuit before normal stresses will diaktifkan.jika there is a problem in the soldered joints (usually located at the point of IC vertical feet, legs FBT, regulator) system will be captured into the protectionist position.
I think that's all and hopefully can be useful for you .... thank you.
