In your case the led flashing is indicating protection mode. That usually indicates an internal fault.

Follow the full troubleshooting below:

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:

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

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

The LCD controller board.
This is 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 this board you need to purchase a service manual and follow the troubleshooting diagrams on service manual.

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

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.

Do we have to manually set the pix set key for every station/show we watch? We loose scrolling writing at the top and bottom of the screen on my dad's new 32" lcd tv bought at Wal-mart. When we set...


Thanks for the offer but we cannot afford to pay additional money for something the Factory support service Should provide.

From what we have heard through the Verizon installer, our SANYO LCD TV probably does NOT have a Automatic picture adjust system. That would most likely be the reason for the maunual button on the remote control. The troublle is that with the FIOS service, you do NOT use the TV's remote control. That leaves to switching back and forth between two different remotes wiich can be vary confusing for someone that is not 88 years old.

It is bad enough that you have to remember which channels you have to go to to receive HD programming signals. If I were making a TV set, and or running a TV network/ cable service, I would transmit both HD and regular signals on the same channel number and let the TV and or the decoder box figure out if my set could display High Definition. Isn't that what we spend lots of money buying equipment and paying each month for service?

If anyone out there knows if the SANYO 32 inch LCD TV sold at Wal-Mart automatically adjust to the picute format, (PIX 1-4) we sure ould like to hear from you.

I just bought a Sharp Aquos LC-32D64U and a Box in the upper right hand corner keeps popping up "Air Analog Ch. 3 Audio Mono/Stereo." The audio keeps flashes either mono or stereo and it does...


The following pretains to most TV models:

Check to see if there is a key on the remote that is called "Display". This is normaly used to display the TV's operation status. Press it and see if you can work your way through different modes of the display content for the screen.

If you cannot make the statis dissapear, it is possible that there is a fault in the incoming signal and the TV is indicating this error, or it is possible that there is an actual defect in the set. At this point, I would contact the dealer. If you don't get a satisfactory answer, then you should contact Sharp service directly.

With retail dealers in many states and countries if you are dissatisfied with the set, you should be able to exchange the TV set in a specific period of time depending on the local laws that deal with consumer sales.
