Re: tv won't turn on?
The main power supply section is not working.
(standby supply is OK)
Common possibilities are:
- High-voltage section (flyback transformer) has failed
(happens sooner or later, about 8 years typical))
- CRT tube has failed overloading the supply
- Power surge has popped the power input circuit.
(Fuse, rectifier diodes, turn-on relay etc)
- One of a hundred of electrolytic capacitors has failed
short overloading the supply. They dry
out with age, are cheap to replace, but hard to find which one it is.
- Or any of many other possibilities.
In short, you need a experianced tech to troubleshoot this.
- If you need clarification, ask it in the comment box above.

I also can't find the remote for my Sylvania
TV/VCR/DVD combo... Model number 6719DF. I don't normally use this tv
(it's an extra spare that I plug into our generator when
the power goes out... since our regular family TV is
quite big and set into the wall making it difficult to
track cords around, I drag this crappy Sylvania down
from our dining room to our family room) I did
happen to find an old Zenith universal remote that
does work with it in some ways (See directions
below). I can turn the TV on and off, set the channels,
language, clock.. etc through the Input select button
on the universal remote but can't set to "Game Mode"
after using connections with video/audio input cords
plugged into the front panel of the TV. So
Playstations, extra dvd players or vcr's, etc won't
Switching from the VCR to DVD and vice versa does
require manually setting the tv itself (remote doesn't
work with that) but at least I can set sub titles, fast
forward through chapters on Dvd's and control the
volume, etc without having to constantly walk over to
Programming the remote: I've noticed a lot of people
have tried using codes supplied by different universal
remote providers and couldn't find a code that
worked using their lists with this particular model...
there is a way that it can be done but it's a bit more
Many types of "universal" remotes give the option of
"scanning" the electronic device for a code if one is
not available or the one provided with lists does not
work... Every universal remote though needs certain
buttons pushed during the "scan" and they are all
different! Ha! So if you lost or misplaced the MANUAL
as well (like me!) you might need to do a search on a
manual for your particular universal remote, but I can
at least give you directions on programming a
"Zenith" Universal remote to "scan" for a Sylvania
TV/DVD/VCR combo model 6719DF:
Using the Zenith Universal Remote or any Universal Remote using it's "scan" method:
1: Shut off the TV
2. Press and hold "Code Search" on the remote until
the red LED light lights up and stays lit.
3. Press the device button for the device (In my case,
for my crappy Sylvania combo, I pressed "TV".)
The LED light will blink once.
4. Scanning: Slowly press and release the "Power"
button on the remote, waiting a few seconds between
while watching the TV to turn on. It's very important
that you pause in between because if you do it too fast
and the TV turns on before you press the power
button again... you'll have to start all over. I've
learned that lesson. It took 160 presses each time on that button to get the
correct code scanned! I had to do it over 3 times
before I stopped myself beforehand because I was
pressing it too quickly..
5. Right after the TV power turns on, press the "Mute"
button on the remote to set the code. It should work with few limitations (no "game" mode)
How to do an auto search for a Livewire Rm-300f+ Universal Tv Remote. These cheap (£1.00) remotes are available from poundland, etc.
1) Turn on your TV, ensure it it tuned to a channel and the sound is on. 2) Press the [set] button for about 5 seconds, until the LED stays on. 3) Press the MUTE button, the LED should flash twice. 4) Point towards the TV and press the power button. Don't worry if nothing happens. 5) Press and release the power button every second or so, eventually (for me about 120 times) the sound will go off. NOW press the [set] button to confirm your setting. 6) Pressing the power button again should switch the TV off. If not you're going to need to go through it all again.
Try this: turn on your tv.
Push and hold code search button until the led light stand.
Release him push and release the device button( Tv,Dvd,Vcr),now you got to push and release the power button until the tv turn off now you push and release the enter button and the code are now on the remote memory.Good luck
