My DTC 6200 converter/decoder was working fine. A few weeks ago I have disconnected it, pull the power cord out of the AC outlet, put the decoder in a safe place. Then when I finish painting, I hook...


Hello
Check out these with your Motorola converter

[1] Verify that the AC power cord is connected to the DCT*
and an AC outlet.

[2] If the DCT* is connected to a switched outlet on another
unit, verify that that unit is powered on.

[3] Press the POWER button on the DCT* front panel instead

of the remote control. The batteries in the remote control
may be depleted

[4] The DCT* may have received a software update and

may not power on while the new software is being
installed. Try again in a few minutes.
OK.

LG LST-5100P set top box does not display menu with an older ( 1998) tv set. Cant select aspect ratios . All I can do is change channels. Any ideas? Rod


Hi Rod,

Thanks for Using FixYa. If its a 4:3 normal TV or a wide 16:9 TV then you can view high definition picture by using the ARC button on your remote control to change the wide mode(Auto,Letter Box, Pan & Scan). Also check its free user manual for more information.

How to remove LG LST-4100A


To remove the LST-4100A commercial control interface from the television you need to follow the commands below.

1. Power on television.
2. Press and hold "MENU" for 10-15 seconds.
3. Quickly press "2-6-6-3" and then press "ENTER"

If you have done everything properly, it will bring up a small menu in the top left hand corner of the television. Kind of a hidden menu.

4. Arrow down to the menu option that says "D Box" and turn the option to "OFF".

Now turn off television and completely disconnect the LST-4100A. In fact, throw it away. In the trash is where it belongs.

Your television will now operate like a normal television purchased from a big box store. You should run an automatic programming setup for grins upon completing.

Enjoy your new NON-commercial lcd television.

LG HD Digital Video Recorder LST 5402P has stopped displaying menu onscreen


first i assume you are trying to watch the unit through AV. If this is the case, turn on unit, press "Display Format" on the front of the unit, keep press it till you have "YPBPR" displaying, press select on front panel, next press "Display Format" again till you come to 576i, press select. Now press menu and it should display. If this problem occurs with HDMI, simply change the display settings to HDMI, and 1080i. Hope it helps, Murder-face.

Remote does not work


Do the buttons on the front panel of the unit work?

If so, try doing this:

Hit the tivo button, go down to messages and setup and into to system information. Go down a few screens until you see remote code. Hold (on your remote) the tivo button and pause button for about 5 seconds. Then hit 0-9 on your remote to set the code. It's a single digit code only. You'll see your remote light flash. Now, try hitting the back button and see if your remote works. If it does, great. If it doesn't that means one or more of the following:

1) Your remote is defective
2) Your IR receiver on the unit isn't working correctly.

If #2 is the problem, you'll need to open up the unit, powered down! and make sure the thin, greyish ribbon cable in the front of the motherboard is 100% in. If it's not all the way in, it will cause issues.

LG LST-5100P set top box. Several times a day have


cap-grant, my friend has the same problem with set top box. When I phone maker I was told it is due to poor and weak signal. You must have 80% signal strength to maintain good picture. When signal strength dropped picture would freeze and had to be turned off at the power point to restart as nothing would work. So I guess what my experience says is you may need better aerial to boost signal and prevent dropout Leonard210
