Had the same problem. The solution: My remote has a button labeled "TV/VIDEO". I must have accidentally pushed this button so when I turned the TV on it was searching for the signal from a VIDEO source. It couldn't find the signal so it's programmed to automatically turn off if no signal is received. All I did to solve problem was I turned TV on and before it could turn off by itself I pushed the "TV/VIDEO" button on my remote to switch it back to receiving TV signal.

Can't hook up a game system to a magnovox 13mt143/17 13" tv


You can, but you'll need an RF converter (also called a modulator) to do it. The TV doesn't have a/v input jacks and can only tune in signals coming in at the antenna connector. The converter takes the audio and video signals from the game console and generates a TV signal on channel 3 or 4 which the set can tune in. Unfortunately, this reduces the picture and sound quality somewhat, but it's the only option for your TV. RF converters are available at most large retailers and online, usually in the $15 to $30 range.

To restore your television you will need to replace the eeprom. Let me tell you why! The stereo decoder and signal processor at one time were confused with the microprocessor. This corrupted the eeprom. Without the following information, repair is next to impossible. Fortunately the repair is near..so pay attention! Location of the eeprom is IC002 on the TV board. You will need to know the numbers on the IC 001 (the microprocessor) and the numbers on IC1001 (stereo decoder). This will determine which correct eeprom to replace. The reason I say this, is there are six different eeproms to choose from. Show this info to a TV tech if you cannot do this yourself. Thanks for asking and show a few a few hands of support.

My pillips lcd tv does not work on 75ohm cable inlet. signal is there because it works on my old tv


old tvs CRTs ( cathode ray tubes) pick up signal better than LCDs
So yes good quality satellite cable with better screening and low loss cable will be better, plus a new aeriel may do the trick.
Is your tuner in new LCD faulty though,? try it on your friends tv where you know the signal is fine.

My 37" LCD maganavox tv won't turn on - it blinks green and then eventually will turn solid green and then the tv will come on. This has been happening for a few weeks.


If the TV goes in standby, then it is in protection mode.

Ensure also that the fault is not coming from a faulty receiver box sending
bad signal, check if you get same problem on DVD with no receiver box
connected.

Try first leaving the TV power cord unplugged for some times, let say one hour or so.

The flashing light indicates a diagnostic state called protection.
When the TV goes on protection there are only two possible causes.

1The internal circuits are jammed because of electrostatic charges accumulating on capacitors, or because of a wrong voltage read by the main chip on your monitor controller board. this started the protection circuit.

2 The protection circuit detected a wrong voltage or abroken contact, identified an internal fault and kicked in , starting the flashing light.

If you are in situation one, then the TV will reset just unplugging power cord for one or two hours,sometimes even minutes.

If you are in situation 2 , then there is an internal fault.

If under warranty contact the manufacturer ringing the number on the user manual

If you want to repair at your own expenses, just locate any good qualified repairer.

On LCD Pay particular attention at inverter and power board, power board can be inspected looking for bulged or leaking capacitors, then tested with a multimeter. The inverter is more difficult to test , there is need to read voltages, should be done by a tech. Also the LCD controller board can cause same problem

On Plasma, test Sustain (Ysus/Zsus) / Buffer boards , cables to plasma, digital board and power board.

On Rear Projection : check lamp, lamp ballast, power board, and convergence.

On CRT TVs, check ballast , flyback transformer, CRT, Tuner, Convergence.

Magnavox 15 inch lcd hdtv


the typical power cord is usually the same kind that is plugged into your monitor right in front of you. Buy another one of those. A universal remote should work (not promising anything)

If the LCD only has coax, it will never display a HD picture quality. However, the Comcast HD Box will still display a picture using the coax connection. So, you could watch any HD channel, but the picture quality will not be high definition.

Attention No Video Input


Check your input cabling and connectors and make sure you have a good input signal. Put another tv on this same input cable and see what happens. Keever
