SOURCE: Channels change by themselves after 20-30 minutes of tv being on

Have you tried covering the IR eye on the front of the TV when this starts occuring? Sometimes other devices in your home can emit infrared light that in rare cases can be picked up by your TV as a command from the remote. If covering the eye seems to stop the problem, I would say my guess is correct. If the problem continues even with the IR eye blocked I would say that the internal tuner of the TV might be defective. good luck!

Bad caps in the power supply. Replace all bad cap or replace Power Supply Module. If you choose to try and fix it yourself yourself will need a ESR Meter to check the caps in circuit. Let me know if this helps.

Distorted picture and color problems


If when you watch tv it is fine then your problem is not with the tv. First eliminate the possibilities. plug your DVD into another tv and see if the problem persists. If it does it is your DVD. Next, replace cables. Not likely but the jack on the tv could be bad. Check those things and let me know if you have any other questions. There is more that can be checked before getting crazy.

How to install with time warner cable box


If your tv has auxilary RCA audio and video inputs on it (red, white, yellow), you can go directly from the dvd player into the TV. Choose the corresponding input (video 1, aux 1,2 or similar) on the TV to watch dvd, possibly controlled by the TV remote. Therefore it doesn't run inline with the cable box via a 75ohm cable.

No signal from samsung dvd-vr375 and tv


That means the dvd (I assume you meant dvd not vcr) needs tuning to the stations. Press menu, then select the tool box icon(or setup) and select the tuning option. Select auto tune and press go(centre button).
Give it a few minutes to tune in and away you go.

Check to make sure the channel down button is not stuck. If it is not the button is probably defective. Mits has had a lot of problems with the buttons.

Unwanted black rectangle on the TV screen


I'm not sure what type of TV you are using,, but most all Large Screens have a reset button someplace. You should be able to reset the TV and fix the problem. Its not the remote, making the image appear, but a command from it was misinterpeted. Sometimes turning the set off will work, but most often it needs to be reset.

EXCEPTION... if you are using a cable box. Disconnect it from power, wait 1 minute and then see if the problem exists. If the cable box is on even with the DVD you may still have this issue. Please reset the cable, and if that doesn't work, reset the TV.
Thanks! //D

Need codes for the RC450 remote


took me awhile but I figured it out

ok

Put your TV/DVD/VCR on
hold in what you want to program TV/DVD/VCR BUTTON
(you dont need codes or anything)
then while holding in what you want to program (TV, DVD, VCR) hold in ON/OFF
both at the same time

when the light comes on and stays on
keep hitting ON/OFF BUTTON
do it slow, when the TV turns off hit the STOP button at the bottom
then hit the button you just programed
then hit the ON/OFF button, the TV/DVD/VCR will turn on

if it doesnt work, repeat. make sure you hit the stop button when the TV/DVD/VCR shuts off, if you hit it an extra time while the TV/DVD/VCR is off it wont work.

took me about 30 mins to figure it out.

I lost my codes too, but I wanted to help all you other people too.. now since I helped you.. check my band out... www.myspace.com/jumpercablenj

Disk won't load


I would verify that connections between the DVD player and the TV; then go into your DVD’s control panel and re-set to original factory settings. I would also make sure that your TV’s settings are set to the correct connection settings as well.
It would also be nice if you included the make, and model of the DVD player and which connections are you using to connect to the TV.
