Screen jump/bounce with main signal board input, hdmi input causes picture disintigration

When using coaxial, video or component the screen or displayed picture will jump slightly but constantly. I switched to the hdmi input after the issue started, no jump to the picture but a different issue developed. After about a week of using the hdmi the screen started to develop an issue with the horizontal and vertical pieces of the display. Such as, the screen will occasionally have a 1-2" blue strip at the top. The screen will also split down the middle and half will twist and scatter different from the other half. The entire time this happens the screen or transmission is visible. After powering down and turning the set on almost immediately it will correct the issue but only for 15-20 minutes or less. I suspect since the main input and the hdmi input boards are separate that the issue might be a power supply, can anyone give me some guidance. Thanks

SOURCE: Vizio GV42LHDTV - No video inputs

my 42 also went black, and the "vizio" logo in front indicates as if it is turned on, it clicks on and off, but just has no output on the screen, meaning not a black screen, just a dead, no image, even when the system has clicked on

I tried turning off, on, unplugging, letting it sit (kind of like a reboot wishful thinking), removed all connections in back, (nothing still, not even the blue screen) just nothing.

What a shame, I had the unit less than 6 months, and now this? I have work to do, and I can't get it done.

Hi:a
Have the power supply checked for faulty puffed up capacitors. You are expriencing low supply voltage to the main board.. There could also be a thermal intermittent on the main board or the TCON board. But for the most part this symptom is related to the power supply.

SOURCE: Over time, my 2007 Samsung LCD TV, model LNT4665F

This TV is known for powersupply failures and this can be effecting the incoming voltages into the mainboard (AKA tuner board). This would cause the noise. Please have someone look into the powersupply and check that the proper voltages are coming from it. If they check out ok, you need to replace your mainboard.



Please rate if this helped :)

Hello
After replacing the main board, you have to do some service adjustments to it. It is a skilled work indeed. You must have it schematic [service manual] to do the work. All adjustment should be done is in it. Without making that adjustments very keenly, the other boards won't accept the new main board. OK.

What do I do when the tv say no signal it just have a blue screen


First you'll need to make sure your TV is on the correct input. By the way, it's likely your TV is ok, unless the input you're using is defective. If you have an external antenna for over the air reception the TV must be on the antenna input and set to Air or Antenna, not cable. If you have basic cable the input must be set to cable. If you have a box for cable or satellite you can use antenna, composite, component or HDMI input. HDMI or component will give you the best picture. At this point just make sure the TV is set to the same input the box is connected to. If you still see the no signal then the Main board is bad.

Check all the cables.
Try using a different type of cable.
if the black and wite problem disappears using a different connection., then the problem was the cable, if not, there is a problem with the signal board.

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.

I NEED SONY BRAVIA T32 FULL MANUAL...how to conect to computer and camera


Hello there,

Here is the link to the full manual:
http://support.sony-asia.com.edgesuite.net/consumer/IM/4110401121.pdf

Before connecting your devices...
The signals that enter the TV and connected devices will need to be output in the correct format using the suitable connections. Below are the different types of video connectors. When connecting the TV, use the inputs that are available on your devices that provide the best video performance.
Video performance level Name Aspect Signal transmitted Separate audio connection required arrw.jpg HDMI cnn_hdmi.jpg Picture + Sound No DVI*1 cnn_dvi.jpg Picture Yes
l.jpg r.jpg
L-AUDIO-R Component video cnn_component.jpg Picture S-Video cnn_s_video.jpg Picture Composite video cnn_composite.jpg Picture RF/Coaxial cnn_coaxial.jpg Picture + Sound No
*1 If the equipment has a DVI jack and not an HDMI jack, connect the DVI jack to the HDMI IN (with HDMI-to-DVI cable and/or adapter jack), and connect the audio jack to the AUDIO IN (L/R) jacks of HDMI IN. (The DVI connector is for video signals only) To enjoy the best visual experience with your system, it is preferable to connect your best devices with the highest quality connections available. For example: your Blu-Ray Disc player or HD Set Top Box with HDMI, followed by your DVD player with Component, then your Video Cassette Recorder with S-video etc.Note: The quality of the picture also strongly depends on the quality of the cable used.
HDMI The High-Definition Multimedia Interface (HDMI) is an all-digital audio/video interface capable of transmitting high definition video and audio signals. HDMI provides an interface between any compatible digital audio/video source, such as a set-top box, a DVD player, a PC, a video game system, or an AV receiver and a compatible digital audio and/or video monitor, such as a digital television (DTV). DVI The Digital Visual Interface is capable of transmitting high definition video, but does not transmit sound. You will need to use the audio connectors of your device (usually Optical/Coaxial digital, or RCA). It is possible to connect an HDMI device to a DVI device using a HDMI to DVI adapter. Component video Component video is an analogue connection. It is capable of transmitting high definition signals. Component does not transmit sound. You will need to use the audio connectors of your device (usually Optical/Coaxial digital, or RCA) S-Video Separate video, abbreviated S-Video and also known as Y/C is an analogue video signal that carries the video data as two separate signals (brightness and colour), unlike composite video which carries the entire set of signals in one signal line. S-Video, as most commonly implemented, carries standard definition video. It does not carry audio on the same cable. Composite video Composite video is an analogue video (no sound) format. This is the connector you should use if you do not have any other connector available, in terms of quality. RF/Coaxial RF Coaxial Cable connection is used for transferring television signals (audio and video) originating from an antenna or cable box to a Television.

I plugged in the normal 3 Video inputs and it still doesn't work.


More info is needed, please. When you say 3 video inputs, what are you referring to? I believe the Sanyo has the HDMI, RGB/YPbPr component video, S-video component, RCA composite video and Coaxial connections, though I'm not sure how many of each. So lets start with the best quality to least.

HDMI: This is one cable that provides both audio & video and produces the best picture quality. It comes in different lengths and is a wide, flat connection. A must for 1080p resolution signals.

Component video, RGB or YPbPr analog component cables: 5 separate RCA cables, 3 of which are video that separate the video signal & 2 audio cables. The 3 video cables are generally red, green and blue (RGB) or marked individually with the letters Y, Pb/Cb & Pr/Cr . The audio cables are red & white. You may see these on the back of DVD players often. They will carry a signal up to 1080i but not 1080p.

S-video component: One cable for video, it is a round connection with several pins in it and will only plug in one way. You must use 2 RCA cables for audio with this cable, red & white again.

Composite video: 3 separate cables; Red, White & Yellow. Red & White are audio, left and right while yellow is video.

And finally there is coaxial which it the cable that is identical to the cable from the pole/ cable box or your dish. It is the poorest quality.

What can happen is you are using 3 standard RCA cables and have them plugged into the component input & they will not carry the signal, or one end in component input and the other end in the composite output or vice versa. Another is that you have the wrong input selected on the menu. Check all your cables and connections, plus the input you have selected on the TV itself.

My hdmi port is not working


I have Verizon Fios and there's a known issue with the motorola HD boxes that they have bad hdmi ports, the screen goes green and that's it, nothing I can do about it I just use component cables. You need to be sure it's your tv not the cable box. Try the hdmi on a dvd player or ps3 or whatever else you have first just to be sure it's the tv at fault not the cable box. If you determine it is the tv you need to replace either the main board or the video board depending on your specific tv model. Some have the video inputs on the main boards some have video boards.

Ghosting problems with a Samsung-LN32B360


I think your cable box is old version together with weak signal caused this problem. I guess you are using coaxial cable hooked up to the TV at TV cable input jack.
At the TV there are some better quality inputs which are real digital transmission (audio and video) HDMI and components (digital video and analog audio).
The most simple and best quality is HDMI provided the box has HDMI output.
Secondly is component inputs. There are 5 cable trends in which 3 of them (red, blue, green) for video and the rest 2 are for audio (red , white). The cable box should have same color accordingly as ouput. Please note that the color must be matched otherwise you will see the screen has one color only.
Playing a DVD player to see picture good or not. If picture is good, TV has no problem at all.

I'm simply looking for the most efficient way to hook up my HD-TV with HDMI inputs to both my cable box (with HDMI inputs) and my DVD player/recorder so that I can record from the TV I watch.  ...


The way you have it hooked up right now will not work unless you have a coaxial out on your cable box going to the dvd recorder. Even then, picture quality will be severely degraded. The best way to do it is to leave your cable box hooked up to your TV via HDMI and connect your dvd recorder to your cable box via component video if your dvd recorder has a component video input. If it doesn't, then just use the composite video input. That way your picture quality will be better and you will still be able to record with the TV off.
