Question about Televison & Video
the symptom is usually caused by a breakdown in the power supply circuit. in most modern receivers (transistorized and/or ic), it may also be caused by a breakdown in the horizontal deflection circuits (hor. oscillator, pre-drive, or drive circuits). supply voltages for the tuner, vif,sif, and vertical output are usually supplied by the horizontal output circuit. but if you doesnt know anything about these stuffs, better bring it to a qualified service technician

It sounds to me like a child lock function, which is usually what the screen + padlock is on TVs. Usually your original remote would have a button / sequence to unlock the mode. If you still have your original remote, look for a child lock button or refer to your remote manual (and/or TV manual for the child lock feature) to unlock the mode.

It might require a qualified hands on tech. But by my experience remote sensor at the TV side wont have malfunction easily. You can still think about the Remote. You can test remote control by your own. How? You need to have a portable AM radio (MW). while pressing the buttons of the remote control you can move the tuning dial (Remote control should be close to the radio within 5inches). If you hear patterned sound it shows remote control is working. The AM radio method is well known and it has over 85% success rate for all kind of IR remote controls fail isolation. You can also try with known working remote control of other devices to understand the method. If remote control test shows that it works contact to service. Please send new posts if you need further assistance.

Try pushing the buttons on the remote and let me know what comes up on the screen if anything.
Display, Channel, 5, Vol Minus, ( Not plus ) then Power. This brings up
a screen with a list of the problems and number of times they have occurred.
Each of the problem names is abbreviated as, "OCP", "OVP", "V STOP", ETC.
We have repeated them in parentheses in the text for the "Blinks" described
above so you can correlate between the diagnostic screen and the blink
