What tensions do you have in the tuner?
Does it change the channel?
Did you do auto programming?
Good morning, does not respond to controls, or show OSD. When turning on the screen it shows rain and the tuned channel, it does not respond to any control, even by the keypad
Does not change the channel by pressing either increasing or decreasing channel?
Check if the buttons are running. You have no menu to do self-program?
The tensions in the tuner are fine, according to the screen printing of the form. I tried the buttons and they are fine, they close the circuit correctly when pressed. The tensions that leave the FB are present
Does this TV have AV input?
Goldstar is self-taught.
Check if the signal reaches the microphone when you press the menu button. Measure if they are as powered with 5v as the receiver. If you put the testet in DC the output of the receiver and press any key of the control this should vary. And so you follow the path to the micro. The same with the push buttons. You may have false contacts or printed cut. Open component Or there is no food.

You already said that. Do not comment if this TV has AV input.
Touch the AFT coil with your finger and see if it downloads. Or in the SW filter. Same to audio IC. It should sound knock knock when touched. If it does it is amplified.
If you can not enter MENU and do auto program you will not see anything. You don't say which channel the TV is on. With control you also can't change the channel?
As a technician you must have another TV walking. The same takes FI to the one who does not walk. Do you know how?
Ready brother Luis, the problem was that the power button was retained and blocked the controls. Thank you for your interest in helping me. regards
