Question about Philips Magnavox 27MS343S 27" TV

2 Answers

My 19" Magnavox won't come on.

My magnavox t.v. will not allow me to operate any of the keys. All it shows when I plug it up(cannot turn on with the power button)is a scrolling message like you would see in the store.Something like "This is the last t.v. you will ever have to buy." Then it flashes all of the different functions. Nothing I push on the remote or the t.v. control will let me operate the thing. I don't know why this message started appearing. Can someone please help?

My MAGNAVOX tv had the same problem. It was stuck in the demo mode and the remote would not work. I pressed all the buttons on the tv at the same time and the tv reset itself.

LOL its in a demo mode man!! simply hit the menu button on the original remote and go to the special settings and turn them off. If it still does not work, then the painter or the Microprocessor Ic Needs to be replaced.

I have a Magnavox digital converter box that won't

if channel is ok when you use only an aerial antenna the cause it could be in the digital converter but if the same problem the cause would be in the channel program.

It sounds that the tuner to your TV is faulty. A detail check is necessary to confirm. Seek expert tech support.

No remote how to turn off cc

You might try a Magnavox brand universal remote. Get one with a "menu" button. Often they give nearly complete control on a Magnavox brand TV. Otherwise, the only real solution is to purchase the exact original remote. There are many vendors on the Internet selling replacements, but often the costs are ridiculous.

Need to program a universal remote to work on Magnavox TB100MW9

Most of these are new and codes do not exist for them. You'll need a universal remote that has a learning feature so it will learn the code. Walmart has them for $16-$19.
