Question about Philips Magnavox MT1931B 19" TV

1 Answer

Power loss every time my power goes out ( even for a second) the TV wants to pull the signal from "inside the tv" according to the cable people here and they say just reset it to pull from the cable. I can't find anywhere in the programming or in any manual to reset anything. How do i make it pull form the cable line again. when i turn off the box i can get pic from the tv alone and it's pulling some of the cable channels but to turn on the cable box attached i get a blank screen. thanks

There are two methods to reset TVs. The first is simple to do; a Hard Reset. The other is somewhat skilled; is a Factory Reset (System Reset). To make it a hard reset, just unplug the TV from AC mains wall socket, and re-plug it back after 15 minutes or so. If you do this by overnight is better. This procedure will make it a hard reset. If you want to make it a system reset [Factory Reset]; you have to enter its service mode option, and select the factory reset option. If you wish to get some details; check the site linked here. Pull up older posts.
Service mode entry, adjust and exit procedure to many popular brand TVs are given. Never forget to exit the service mode, after all adjustments have been done.

SOURCE: magnavox with pic tube tv skips over channel 3..goes from 2 to 4

You are right about the auto-programming, but Magnavox no longer has the original remote.

For my answer to be right, you must have posted this question to the EXACT CORRECT model # of your Magnavox TV - 27ms343s:

Press TV on your Verizon remote, and then press "0" and "3"

If that fails:
Press MENU to see the TV’s on-screen
menu. In the menu, use VOL.+/_ and
CH.+/_ to make adjustments or selections.
You can press MENU on either the
remote control or the front of the TV to
access or remove the menu.

SOURCE: blue,red,green lines on top of screen for couple months. Now tv wont work.

The foldover is because of a bad capacitor in the vertical circuit. Given the "new" sympotom of a dead set, I would suspect that the vertical IC has failed. This should be a relatively simple repair for a TV shop. If you wish to attempt a repair of this yourself, update this and confirm your model number and I'll post more details and instructions.

SOURCE: TV set self turn off after few seconds

It sounds like the voltage regulator in your power circuit. Also you have a capacitor that's going bad somewhere and won't hold a charge. That's why the picture is fine for a while then turns green. Unless you service TV's this one will have to be brought into the shop. Unfortunately it'll cost more than the TV is worth to get it fixed unless it's still under warranty. These days TV's that small aren't worth fixing. You're better off buying a new TV.

You need the Horizontal timing kit installed in this tv. Ask a tech to install part# 4835 310 57673. You have tv chassis# L04.1U AA...correct? Look on the rear of your TV. This will repair!

My TV Goes Off and On

Its not your tv that is the problem unless it is shutting off altogether. If your tv is turning off then check out the ballast assembly. If it's just the signal going in and out from your directv, then sorry but that's your box that is the issue not the service itself. Check out what model of box you have and they are known for blowing capacitors. If you are in contract still then complain to directv. If not then I suggest finding a used one or open up your box and see if your capacitors are blown. If you don't know what those are here is a good basic video:

Second level tv has a signal but the main tv on first floor has no signal.

Hello! It sounds like there are a few things that could actually be going on. If you are getting no picture on the TV(you have a black, blue, or snowy screen), you will want to make sure that the TV is on the correct channel and/or input. You will want to be on channel 3 or 4, and possibly on a Video 1 or 2 or HDMI 1 or 2 input. If that doesn't work, then try unplugging the receiver from the power source for about 10 seconds. If you are still not getting a picture, let me know!

If you have a signal loss message on your screen (Signal has been lost, Partial SIgnal loss, COmplete signal loss, or Acquiring signal), you will first want to unplug the receiver from the power source for 10 seconds. You will get the Acquiring singla message as the receiver reboots after you plug it in, but that should only be about 5 minutes at the most. If you get the message after 5 minutes, you will want to make sure that all of the cables going from the back of the receiver to the wall are tight. If that still doesn't do it, please let me know!

According to SharpUSA the problem with the "Loss of Sync" error message is that (most probably) the cables (between the box and the display) are not connected properly (so remove and reconnect them carefully, on both units) or a cable is defective. 

Also, after you reconnect the cables try turning on the unit, if no success then depress the "clear" button on the external box (under the door on the front and on the bottom left and try turning on the TV again). 

It is, most likely, that the cables are not seated properly. Reseat the cables on both the display and the external box. 

Hopefully, this will clear the problem
if still does not solves your problem just replace all the cables connected between .u can get the new cables at radioshack web site.just place an order they will provide you. thanks.

Some of the newer TV's dont turn on if there is no input signal. Try a DVD player and see if that works. If it does, then the issue is most likely with the cable jack on the TV, which may need to be replaced..

37" Polaroid LCD TV No signal appears when select channel

I was having same problem, and think I got lucky and found fix.

Try unplugging the TV and waiting 30 seconds, then plug back in.

You will likely get blue screen with "No Signal".

Go to Menu, then scroll down to "Setup". Select "Factory Reset" then hit "Yes."

This did it for me. Wish you all luck.
