SOURCE: No picture, sound works, but along with high-pitched noise

My guess is that you might have the yellow (video) cable plugged into an audio input on the TV. Make sure that the yellow cable is plugged into both the video out on the DVD player and the video in on the TV. Most of these connections are color coded.

As a diagnosis, try changing the TV input (using the remote) and let me know if you still get the buzzing on the other inputs. If no, then, it's most likely your RCA connections. If yes, it's another problem.

SOURCE: ViewSonic TV sound but no picture

If an LCD TV has sound but no picture do the following:

Use the source button to ensure that source is not set to the wrong input.

Try unplugging power cord for ten minutes, to ensure it is not a setting problem.

Check all the video cables at the back of TV.

Check Light /Color settings.

If problem persist and does not depend on external receiver or settings, then it is likely an internal fault.

If it has sound but no picture then one of the following parts is faulty, and must be tested and replaced:

Theinverter is the high voltage board that provides variable power to thebacklight lamp. This is the most common. When inverter is faulty youcan get no picture, or a very dim picture that can only be seen bypointing a torch light with a 45 degree angle on the LCD surface fromvery near distance.
The inverter must be tested by reading voltages with a multimeter.

The LCD ribbon cable/LCD display and connectors.
Thisis quite uncommon, but happens. If the TV had been hit or moved the LCDcable may have slipped out, or the LCD connector may be damaged.

The LCD controller board.
Thisis the board that controls the video signal, it is difficult to test,as there is need to read determined values on IC pins. To test thisboard you need to purchase a service manual and follow thetroubleshooting diagrams on service manual.

Input/Output Signal boards.
This are the boards where youconnect the video and audio cables, if a signal board is defective,then you may get no picture on particular inputs located on faultyboard.

If under warranty contact the manufacturer ringing the number on the user manual.

If you want to repair at your own expenses, just locate any good qualified repairer.

SOURCE: picture goes away not sound ,hit the back of tv

You need to take the back off the set, with the power off, turn it on, then probe around with a long, wooden chopstick until you find the problem.

Try resetting, Not sure if this works for your model
Power off the TV, hold down the reset button on the remote and power up the tv with power button on tv while keeping reset depressed.
(Is there a restore factory setting or reset buried in the on screen menu? I couldn't find it in the manual, can you let us know if there is?)
here is the manual in case you don't have it

My netflix is running slow..the sound and picture don't sync up what causes this?


The problem is that your internet speed is not fast enough from your provider. Call the provider and see if you can move up to faster speed and that will help your problem

Picture comes out blurry


There are three main reasons for blurry pictures.
Pictures may come out blurry if they're not focused properly. If some objects are sharp and others are not, this may indicate focusing on the wrong subject. This is usually not a major problem with compact point&shoot cameras since they have such a wide field of focus that almost everything will be in focus anyway.
Subject motion. If moving objects blur while stationary objects remain sharp then the shutter speed is too slow to freeze the motion. Try switching to the sports mode, and/or add more light.
Camera motion. This is the most common cause. Set your camera on a table or other stable surface and use the self-timer to take a picture. Take another one while holding the camera. Compare the two on your computer.

When i was taking picture the lens of my camera ( sony dsc-w120) become blurd. why'?


The cameras capacity to capture motion pictures is disimpressionful. Usually cameras have feature functionalities either as still picture shoot or motion video recorder devices. Cameras may have any once of the mentioned features or both as complementary for videographic requriements. Inspecte the camera for capacity to capture motion picturee. Usually, the lense capacity with pixel capacities are indication of extensive capabilities. An impressionful camera producign disintergral result requries adjusting the lense or pixles buttons prior to photo shut. Also, cameras that least have the pixel capacity requires photo shoots at still motion or at calm climate least onbracting activities. Capture pictures at areas that least have movement caused by human interfernce or windy or suny blurs. Also, capture pictures maybe retored of blurry filming from computer photo video editor programs. Capture the picture or videos to be loaaded on to a computer that allows editting to achieve desired interfaces.

Screen becomes unviewable


Sounds like a problem with the graphics card or on board video. Please state which one you have and type. The last option is a bad monitor. Try Degaussing it first on the monitors menu selections. If you use a graphics card, you can disable it and try the on board one to see if it helps. If you need further assistance, please ask. I can guide you through all the steps.

Picture problems


Sounds like a problem in the main power regulator circuit, such as a bad capacitor or regulator IC or transisitor. There are no user serviceable parts inside these sets and every thing is soldered into place. I recomend that you call in a trained service tech to assist you with this repair.
