The first thing to do is determine if it is a problem with the remote's transmitter or the TV's receiver. To do that, you'll need a different remote capable of controlling the TV. This can be a replacement universal type, one borrowed from someone with the same TV - or bringing your remote into a store that sells these TVs (and has them on display). Try to control the display TV with your remote.

If you can work the store TV with your remote - then the problem is with your TV. If you can't work it - then either the TV will not respond to your remote due to being a different model / year / etc. (this does happen from time to time) or you've got a faulty remote. Before leaving the store - look for a universal remote. RCA and others make them and they can be had for under $20. Check the packaging to see if your TV is compatible and buy it. Save your receipt.

Bring it home to see if it can be programmed for your TV. If your TV is supported but it fails to control the TV - the problem is likely to be with your TV. If it does control the TV, the problem is likely to be with your original remote.

I do not recommend opening the TV to try to "fix" it. Bring it to be serviced or deal with it another way (cable box, etc.). If it is the remote - which I suspect - you *may* be able to open the remote *carefully* and see if the LED behind the red plastic lens is aimed away (from dropping, etc.). If it is - bend it to point straight out of the remote and reassemble. If it works - bring the new universal remote back for a refund. If it doesn't - toss the old remote and use the new one. :-)

Hi, How long have you had the unit? What is the model number? Thanks, Mike H

If your Magnavox DVD player has outputs for left audio, right audio, and video, they connect to corresponding inputs on your TV. You may be misconnecting the wires.

how do i get this fixed

TruTech... | Answered on Apr 20, 2013


Not sure what is meant by this question: if set has sleep timer it will be on the remote or in main menu.

If the set shuts off after turned on that is a different issue.

I suddenly have the exact problem you describe. Did you ever find a solution?

TruTech... | Answered on Nov 03, 2011


Your backlight is probably faulty and requires repair.

TruTech... | Answered on Sep 17, 2011


it could be the settings on the cable/satellite box. Make sure that it is set to 16:9 turn off/disable any 4:3 override or native resolution setting, and set the resolution to 720p. Make sure to accept and save the changes.

If the television isn't connected to cable or satellite box and this happens no matter what the television is connected to and on all of its inputs then it could be loose

No,there are no HDMI ports in this tv design.This lower end of LCD tv made especially for Target it only get to resolution max 720p,so no HDMI ports.Only can connected devices as RCA component cables Yellow Red White only as for AV input for external devices attactments.

You may either have bad DC filer caps for the 12~18vdc power supply section that supply the power to the backlight inverter board, or the inverter board is bad, worst case will be bad lamps. Check the 12~18vdc first.

Hi
To check the remotes use an old AM radio and set for about mid band. You should be able to here the data static from your remotes when you press different buttons. If all the remotes are OK, then it's probably the receiver board inside the TV.

TruTech... | Answered on Jun 12, 2010


This is usually a power board or a ballast (also called the inverter). You eliminated the power board so the only remaining cause is the ballast. In most cases, this part is supplied with the LCD panel only. However, you should remove it from TV and inspect each transformer visually. Many ballasts that act in this manner have a failing transformer. You may be able to cross reference the part to find a suitable replacement part. I hope this was helpful, best wishes.

Hi there,
Just wondering if they were new or second hand boards you used. I would be inspecting the inverter circuit for the back-light is causing the problem for you. Short of replacing that also,I would be looking at repairing the area itself. If you have some electronics experience and the tools required...common problems you may find are
  • dry solder joints about inductors, power transistors and components that run hot. The heating and cooling associated with running then turning off produces dry solder joints over time.
  • replace electrolytic capacitors in the inverter stage. They can also over time dry up and their effectiveness be reduced.
The fact that it operates for 1 min makes sound like a heat related problem. There are methods of determining problem areas using freeze spray to cool individual components to determine if they are the offending part. Be careful to avoid moisture build up condensed from the air when using this method. Gentle prodding of the individual parts and spots on the PCB with a plastic tool can also help to locate any dry solder joints. Hard to tell you exactly where to look, but with perseverance, you may get to the bottom of it.
