Olevia 237-T12 Hi guys. I am an appliance repair person. My Olevia comes on, but will accept no remote or panel commands. Sometimes for 1 command, then displays channel only with black screen. This is when plugged directly into cable line, no box. Any advice. 1 year old. Thanks, Scott in Upstate NY

After taking the screws out and removing the back, you will see a power supply(where master switch and cord connector are). Remove the 4 screws on the aluminum cover plate to gain access to the fuse. Using a voltmeter, with the power on and switch on, measure the voltage on each side of the round fuse located just behind the cord connector. If voltage is 0, fuse is good. If voltage between 115 and 125 V, replace fuse or have fuse replaced. I think it is a 6.3Ah 250V class fuse that is soldered into the board. IF YOU ARE NOT FAMILIAR WITH SOLDERING TECHNIQUES AND PRECAUTIONS, DO NOT ATTEMPT TO DO THIS. IF YOU ARE NOT FULLY AWARE OF ALL SAFETY PRECAUTIONS NECESSARY TO MAKE THIS REPAIR HAVE A QUALIFIED TECHNICIAN DO IT FOR YOU!!!!!!

We had this same problem as well and we finally found the answer, the code for the COX remote (silver on top black on bottom) is 1240.

Testimonial: "Thank you, Leppar, Thank you for your solution to my problem. Now I don't have to mess with two remote controls to operate the TV. "

It may abe in the safety shutdown mode due to short circuits in the power supply or in the backlight inverter board.

I had the same problem with the exact same TV. I took it to a local TV shop. My problem was fixed by replacing the T-Con controller board. The cost of the part was about $85 and labor $125. There are no "new" parts out there for Olevias because the company is out of business but I did find a part pulled from a "damaged in transit" TV. It's a personal decision (assuming the parts can be found) as to if its cost effective to repair the TV.

Replace the power supply.
