If you brake power you may damage irreparably the unit, you will need to call Toshiba tech support by phone.

hello,
you can solve this by opening the back cover of the DVD player.
first clean the lens with a dry cotton bud to clean the lens , you have to do this with care because the lens is fragile.
secondly, power on the player and check if the lens beam up a red light, if it does not the problem could be from the ribbon cable use to connect the lens to the printed circuit board or the lens may be faulty,replace to confirm the faulty one.
take care...

while recording the real time can be showing / remaing time of the event being recorded /timer clock will showcase the speed if enable or alert if there is a problem and if all is well the a red dot should also be showing

Your track is stuck, you need to try and find something thin & lite to slide under your dvd track and kind of push it in an upward direction to eject. This should throw your dvd track back in place.

have you tried to tune in the recorder to the film while its running.i have also found av button has four setting

shut down tv/dig box/dvd. unplug and then leave a little (cuppa time)
replug .then start up dig box then tv then dvd.sounds like in need of "reboot"

Could Be a Bad Drive.
These units sometimes take a long time to boot.
Wait about 5-10min.
Replace Drive

While this post is very late to answer this question, here is where I found a solution with the DVD still inside. When I used this solution, the whole system reset and worked.

"I had the exact same problem tonight. I put in a DVD and it locked my Toshiba RS-TX20 up. It simply wouldn't respond to anything but unplugging. Then it went into this infinite loop of trying to power up.

I finally got it to boot:

Hold the eject button on the unit continuously while it boots up (be patient!). It didn't open the tray until a couple minutes into the powering up process. After I took out the disc, it booted up normally at the next try.

I am guessing that there's a very small window during the booting process that the dvd drive isn't locked and you have to push the eject button in that small window to get the tray open. Since we don't know when the drive is unlocked, the best bet is to hold down the eject button continuously.

I hope this helps!"
