Hi there, i'm having the same issue as you now for my toshiba LED tv. Can i know what was the solution for you in the end? i can't find the toshiba number to contact also.

First thing to check is to see if USB port is physically demaged. If your TV has more then 1 port, compare them otherwise use the PC USB port as a reference.

Forget about repairing Tv unless original part.

Look into the socket and inner part of the socket. There should be 4 flat pins. Check if they are demanged or get pushed in.

Hi I am having the same problem with the Toshiba tv, look into the usb socket and doesn't see any damaged or pins getting push in. Weird thing is nothing is plugged into the usb socket and yet the annoying error msg appears. Any other solutions? Anyone managed to solve this problem please help.

Perhaps plugging in a dispensable thumbdrive may help?

Try plug in some USB drive to each USB socket see if the TV can detect it.

Thank you both for the reply I try plugging in a thumbdrive still get the error. Try plugging in a air mouse TVs was able to detect it but still get the error. The problem is I can at most watch the tv normally for less than 15mins for the error to appear and the TVs just hang dead there even pressing remote also useless have to switch off the power.

The error is as follows usb over current status detected. Please remove all usb devices from the TV and restart the TV by removing the ac power.

Looks like you have a real electronics issue. Chances is you have to get the board replaced.

My Samsung TV cannot turn on and no standby red light.
Ask a few shop and they said need to assess onsite if change board cost $160 or more.
At the end, I called the Mr Ho to come my place and fixed the power board issue. He spent about an hour to check and replaced some faulty components on the power board.
Mr Ho is very patient and details person. Very satisfy.
Total damage is $90. And hopefully after repair and last for a few years more.
