Make sure your sensor is in clear view and nothing is interfering with the signal.

hi Shaun Mine started this morning. If you find a solution please let me know [email protected]

You may need to now reset the player, that may have been a bit much for it.
To reset your Sansa Mp3 player.

1. Slide and hold the Power switch up for approximately 20 seconds.
2. Release the Power switch.
   
3. To turn the player on, slide the Power switch up then release instantly.

If that does not get your player working again, try and Format to clear any corrupt files that may be present.

Could be power board. Check for swollen capacitors . If ok next check buffer boards for burnt ic. With set unplugged unplug power board from sustain boards. Plug back in and see if it turns on. Unplug again and disconnect buffer boards from sus board plug power supply back into sus to see if it powers on. If it does then buffer boards bad. Isolate upper and lower to Determine which one is bad. Just always remember to disconnect power board from sus boards when disconnecting panel to buffers. Power supply stores a lot of energy and will burn these connectors while reconnecting them.

Replaced swolen capacitors on power board would be first thing. see long thin boards up side. are any of the ics pitted in the center. If so change that board also(buffer boards)

Bring your TV to eletronics technician. The main power of your TV has a broken semiconductor parts that need to be replace. ( Maybe power mosfet, fuse, transistor, capacitor, etcc ).

Unplug the power for 5 min to reboot the curciut board. Sometime multiple comands in a short period of time can overwelm the little brain in the curciut.

Most likely a power supply failure. It apears that the power supply is not putting out all necessary voltages.

Replace the power supply

this issue might not be because of your Monitor. Anyway, I can only provide manual to this legacy product of princeton if you want...
