SOURCE: Samsung 46" LCD TV stops responding

Ok, There are well three boards in this set that would influence such a behavior. The culprit is the Key Pad Board. It has what is called a leaky switch. This then locks up the Microprocessor. This will result in the set operating like a ghost has the remote.

best regards

Try to reload the the remote by using the universal remote code for comcast cable.This number should be available in your owners manual or on the Sharp website. You should search the websites frequently asked questions and troubleshooting sections for you model of television to see if someone already has had the problem answered. If all this fails you must contact the customer service for both the remote and television and get help. Hope this helps you with your problem.

SOURCE: I have an RCA TV

The fact that the screen illuminates properly and does not stay absolutely pitch black means that the backlights are working properly.

A faulty LCD Controller Board (or TCon board for short) could possibly cause the symptoms you describe. The Tcon board is usually located under its own RF shield and will have a large braided steel multiwire cable coming into the bottom of the board and several flat ribbon cables connected to the top by little plastic flip up connectors. A replacement board can be purchased on Ebay for around $70 plus shipping. See the following link for one example:


http://cgi.ebay.com/LCD-CONTROLLER-V320B1-L01-C-RCA-L32WD12-/360142646595?pt=LH_DefaultDomain_0&hash=item53da2cad43


Just use your mouse to click on the link, which is the underlined and highlighted text just above. This will open a new web browser page automatically for you and allow you to view the item information at the website indicated.

Just don't buy any that say AS IS for their description of condition. That is EBay speak for broken.
Make sure they say TESTED FULLY WORKING in the item description.

The best way to be sure you are getting the right part is to open up your set and check the part number that is printed directly on the circuit board itself. Then look that part number up on the internet or type that number into the EBay search box.

Just typing in the model number of your TV will sometimes give you a few different part numbers so you have to confirm which part is in your particular set.

Make sure any part that you order online has exactly the same part number as the one you are replacing. Sometimes it it just the last few digits that are different and it can make a difference.

Here are some links to some excellent LCD Troubleshooting Guides from another expert (BUDMRTN) that you can read through and get an idea of the LCD repair process:

How do you get the picture in picture to work? What two sources can you use, a cable box and what?


The Picture in Picture (PIP) on VIZIO televisions works on multiple input sources. This means you have to have signal or a device connected to more than one input on the television and have both inputs selected to display the information going to them. Here is an example. Let's say you have an HD cable box connected to your television and you would like to have more than one channel displayed on the screen in order to keep an eye on both football games at the same time. With one device connected that's not going to work out the way our TV functions. What you want to do is get a coaxial splitter and two extra coaxial cables; these can be found anywhere home theater equipment is sold. Then follow these steps.

1. Turn off both your cable box and television.

2. Take the coaxial cable that comes OUT from the wall and connects to the IN of your cable box and disconnect it.

3. Connect that cable to the IN on your coaxial splitter.

4. Connect your two extra coaxial cables to the OUTs on your coaxial splitter. We will call them cable 1 and Cable 2, just because.

5. Connect cable 1 directly to the DTV/TV input on your television.

6. Connect Cable 2 directly to the IN on your cable box, this will be the same connection you removed it from in step #2. Your HD cable box should still be connected to your television with either an HDMI cable or Component cables (Identified by their Green, Red, Blue colors for video and Red and White cables for audio.)

7. Power on both the cable box and your television. Using the INPUT button on your VIZIO remote select the input connection where your cable box is located your cable box picture should come up on the Main screen.

8. Press the PIP button on your VIZIO remote to bring up the small box in the corner. Press the PIP input button until you select the TV input and you should be ready to go. You may need to perform a channel scan with your TV tuner to locate all available channels before you do this step. In order to understand better how to perform a channel scan please check under the F.A.Q.s in the discussion area of your particular model television.

In order to change channels in the small screen use the PIP CH - and + buttons located near the bottom of the remote. You can swap picture in the Main and Sub screens using the swap button and swap which screen will sound off its audio by using the AUDIO button. You might notice an X next to some of the selections in the INPUT and PIP INPUT screens when you have PIP activated. That means that input selection is unavailable and cannot be used. For example, if you have the input TV selected on your main screen then if you press the PIP INPUT button and bring up that input menu you will see X's next to the TV and AV selections. The X's mean that when you have TV on the main screen you won't be able to use TV or AV on the small screen. Instead you would need to use any of the input selections that do not have an X attached to them.

DVI Alert, your HDTV does not support HDCP. what does this mean? Please use YPrPb component connection to watch


Ok so, I was having the same exact problem but I got mine to work.

Make sure you have your HDMI cable is connected from the TV and cable box....

1)Turn off your tv and reboot your cable box (my cable box was rebooted by pushing the following buttons AT THE SAME TIME: "info," "vol ," and "vol-").

2)Once your cable box reboots completely, power it and the TV on...

3)Push your INPUT button on the actual TV REMOTE. Give it a couple of seconds and then use your CABLE BOX REMOTE to begin switching the channels. Your HD channels will be in the 600's if you have the same cable company as I do.

Hope this helps...it worked for me

NOTE: Your COAXIAL should only be plugged in from the cable outlet on the wall to the cable box. Your HDMI cable will be the one to plug FROM the CABLE BOX to the TV

Samsung 40 hd tv the vol will not come down from 100 percent . I try to turn the vol down and it will not turn down. what can I do. tks mike


I presume that the volume will not turn down from either the remote control or the volume buttons on the side of the tv. If the volume down button works on the side of the tv then the remote control is suspect to be faulty. If neither remote or tv volume buttons work then check whether the channel buttons work on the tv (not remote). If none of these work then check the input connection from the buttons /infra red reciver to the main pcb. This is a push on cable connector. As a point, also check that the volume up button on the tv is not stuck in, and feels the same as the other buttons when pressed.

Lux Audio 5.1 home theater speaker & Yamaha HTR 5540 AMP


configure ur PC (both OS audio and third party sound driver) for surround sounds. control panel- sounds and audio devices - speaker settings - advanced - speker settings. so this done. make sure u select the 6 input channel - the button is on the right edge near the volume knob. near the vol button there are two buttons for selecting input type with up down arrow. from that u can select the input type this will be indicated on the top front indicator. but with the 6 input channel selected all selections are preceeded. if u select stereo mode u will have left/ right audio only.
make sure u connect the input right. connect from computer to 6 channel input. main, surround, center and sub-woofer.  connect the spekers to main (L/R), rear(surround) (L/R), center and sub woofer to terminal marked sub woofer ouput. this done select like i said before the 6 channel button. that should do it.

Power on problems


this worked for me before, but now the problem came back after being fixed for months! unplug the two connectors at the back of the tv, the ones that look like computer monitor cables. then go to top of tv and use manual controls, turn off main power, then turn on while holding input and vol down button, a small service menu will come up, use the channel up down button to go to test, then push input button, there should be a box with reset and some number in red. use the vol buttons to reset to 0, then power off.... reconnect the cables and then turn on the tv.
