Hi redneb711,
I am happy to help.
The cover on the back of the tv has to be removed. Facing the back of the tv at the bottom of the cover on the sides are Arrows, press in on these arrows and pull towards you.
The cover should hinge from the top and come off.
The power adaptor plugs into the bottom hole below the inputs.
I have provided a link to the manual.,20DL74.pdf

let me know if you require further assistance and please rate this solution. Lone99star

Toshiba tv won't change channel -remote not working and press buttons on tv, but just get channel1.can change volume and input no problem.

Many electronic devices today can be reset by unplugging the power cord and waiting 2 to 5 minutes and then plug the power cord back in.

Will not power up


If your television will not power up, there is just one problem related to this, and that is the power panel. But before You confirm it is the power panel, You will have to run a test on some components to be sure that it not other components before You go ahead to replace the power panel of the television. The components to tests are the power outlet, check if the voltage is not too high or too low to power on the television. Then You also test if the cable that connects the television to the power outlet is not bad by using it on another television and trying to use the another power cord on the television, then You confirm if it is not a blown fuse on the power cord. Once that is confirmed, then You can go ahead to replace the power panel of the television. To replace the power panel:
  1. Get a screw driver, a glove a cup and a replacement power panel,
  2. Unplug the television and put on Your gloves,
  3. Turn to the back and unscrew it open,
  4. Keep all screws in the cup in order for them not to get missing,
  5. The power panel is the panel that the power cord is attached to at the back of the television, remove it,
  6. Fix in a new one
  7. Reverse the process to reassemble the television back together,
  8. Plug it into the power outlet and power on the television.
It should turn on now.

Hope this helped. Thank You for using FixYa!!!

Yep! I agree - your tuner on the TV is not made for Digital reception.
You will still need to use the Verison Cable box to view any channels.

The newer TV's have the digital Tuners built in. Note: Plasma's are faster locking on to channels than LCD's.

Go through the pages to see how to tune it on, but if you there the method and it has not solved the problem yet, then you need to take it to Toshiba servicing center for service.

Hope this helps!

Toshiba TV will not turn on ....

First off! Is it still under warranty?
If not my thoughts is either one of two things,
1) a bad or problematic power supply
2) the lamp ballest 'florecent tubes' for back lighting is going bad or bad.

Toshiba 20DL74...on/off

I had the same problem with mine and I finally figured out it was the power supply. I ordered a new generic replacement and I have'nt had a problem since other than a few noise lines in the lower channels and that might be because I didn't buy a Toshiba replacement which may have a filter in it. It has not shut off now for over a year.

TV loses all power

I had same problem. Finally figured out the power supply was the problem. I ordered a generic replacement and it hasn't shut off again for over a year. The only thing I have notice is there are noise lines in the lower channels (1-6). This may be beause the Toshiba power supply may have a noise filter in the power supply. But the generic was $30 compared to $80 Toshiba

If it's less than a month old, you shouldn't have taken off the back. I subjest taking it back to where you bought it from and get it exchanged or get a refund.
