Question about Flat Panel Televisions

Open Question

Magnavox MS4504 27

The green "power" light turns on momentarily, but the TV fails to come on all the way.  When I press the remote or the Power button on the remote or TV unit itself, I get the same result.  The set "clicks" and the light comes on as if it is going to "turn over" and start, but nothing happens.  This is the first time it has happened and I've had the set for a year and eight months.

Without testing I wouldn't suggest the Power supply is not defective: 1st, the control module is working because you gave it an ON command, 2nd the SMPS has received the the start up. The secondary voltages for the Y sustain and Z sustain modules are shutting down, probably due to a shorted IPM on either of the two modules mentioned. This problem is one you should contact your nearest svc center for a complete diagnosis. If I can be of any other assistance please e-mail me.

SOURCE: No power to TV

Most likely the TV has a power supply related problem. Or, it can be something simple like a burn fuse inside that needs replacing.
But, I can't say it's 100% the problem because I can't actually look at the tv over the internet.
If by chance the TV is still under warranty, go that route.
If not under warranty and If you have some electronic experience, if you can find and purchase a Service Manual over the internet; It will help you diagnose the source of the problem and fix it by soldering in the new part. The Service Manual will give you circuit diagrams, test points, and part# lists. Usually, cost under $20. And most cases the new part cost less than $15.

I hope I shed some light on the subject for you.

SOURCE: Magnavox 32mf231d - Just a blinking green light, No Power

Our 37" Magnavox was having the same issues posted here. Blinking light. My husband and I FIXED it for only $5 and an hour of our time. People stop complaining and give it a try. What do you have to loose? It was a very easy fix.You will need to remove the old capacitor, solder the two wires on the new one in then put it all back together. That is it. If you feel unsure about where to put parts back, take pictures for review. I used the same 2200 @ 35v capacitor like the person that posted the pics. Very helpful by the way.

Can set up th remote control for this tv with the direct tv cable remote

Here's how to scan for TV codes on your DIRECTV remote

1.Make sure your TV is turned on.

2.Slide the mode switch at top of remote to "TV".

3.Press and hold the MUTE button. This is located above the number 1 button.

4.While still holding down MUTE, press and hold the SELECT button until green light at the top of the remote flashes twice.

5.Then enter 991, the green light on remote should flash twice.

5b. Press 1 again (it will flash twice again), then you press the power on button at the very top right.

6.Point remote at TV and press CHANNEL UP button. Tap the CHANNEL UP button repeatedly until the TV powers off.

*If you hit channel up very fast, you risk going past the code. Pressing channel down will back it up. I alway hit channel up very fast till the tv turns off, then back it up slowly till it comes back on.

7.When the TV powers off, press and release the SELECT button.

*Note: If the green light flashes three times before TV responds, then all codes have been cycled through. Our remote controls are guaranteed to program to your DIRECTV receiver, however your TV may not be compatible with our remote control.

The TV was turn ON for the first time or the TV reboot/reset.
Universal remotes are not as "universal" as we like them to be. They only control a very, small amount of options for the TV.

You'll need the remote that came with the TV to fix this problem because it has the special RED, GREEN, YELLOW, and BLUE buttons you need.
If you don't have the original remote, you can get one at this web site. It's the best price going right now. $29.95

Magnavox 15mf605t/17 15'' LCD HDTV won't turn on

Have similar TV. If it is set to the PC source, it goes into standby when there is no signal, like a regular monitor. Even though the monitor is in standby, you can still press the Source button to change to, say, HD input, and will use the familiar on/off action when pressing Power on the remote.

A little weird, but I've gotten very used to it.

Screen says attention no signal

Your TV is probably on the PC mode and you are not using it as a PC monitor.

You need to change the source by pressing the TV/Video button on the remote control or the SOURCE button on the TV itself. You may also just press the channel up or down buttons. Do this before the TV goes to standby mode (amber light) or while it shows the message: ATTENTION NO SIGNAL.

If it does not work, reboot the TV first and do this again.

My magnavox 37mf321d 37 LCD tv

This is a bad power supply and an easy fix. Their are several electrolytic capacitors on the power supply. If one is bad it will have a bulge on the top. Mine had a bad 2200uF and a bad 1200uF capacitor. About $7 worth of parts at Radio Shack. Radio Shack had the 2200uF but it was axial leads instead of radial. (leads come out of each end instead of one end) but It will still fit. They only had a 1000uf capacitor so I combined that with a 220uF capacitor and wired them in parallel. Make sure you put them in with the correct polarity.

15M170V will not power on

The TV is in some kind of protection mode, the blinking LED show you an error code.
Try pressing 062596 and then press menu button (do these in quick motion, don't let them to time out while keying)...see what happens
I also heard that this problem appeared with some people because the of the burnt fuse in the TV. To fix that it has to be taken to the tech shop. mecry.gif
And yes I also heard about this issue many times, seems like this TV set is very popular with this kind of problem.
