Question about Toshiba 20DL74 20 in. EDTV-Ready LCD Television

1 Answer

Toshiba 20DL74...on/off I bought the unit on Dec 13/04 and it has performed well enough since then. Recently, however, it stops and turns off suddenly and won't turn back on. I have tried different electrical outlets but no luck. Eventually, I disconnect everything (cable, power adapter) and then try it elsewhere and it works again. This has happened about five times now over the past month.

Re: 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.

My sharp tv is 7 yrs old. It had been running smoothly since it had been bought. But recently it shows a running problem. It suddenly stops while running. how am I to get rid of this problem?

Older tv like yours encountered almost the same problem like what you have experienced right now. It is because some of the electrolytic capacitor began to dried up most especially on the low voltage power supply. It is not DIY and quite technical so I've advice you to look for a qualified technician to isolate the faulty parts. Leaky electrolytic capacitor will affect the performance of the power supply, once sense by the processor it will shuts down your unit automatically.
Theres a series of test that will undergo to fix the problem.
Please rate my advice.
Thanks 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.

Hope this helps!

First try seeing if your dvd has a options button on the remote.If it does you may be able to find the specific choice that lets you reset it.Otherwise try turning on your dvd and having it run without a disk in it.A dvd menu itself might show up and give you options.

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.

20DL74 toshiba- Power cord was missing

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

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.
