I have a Toshiba DVD Video Player Model SD 260. I


Hello, The problem could be dirt on the surface of the lens, you can clean this by removing the cover of the dvd player . Gently use a dry cotton bud to clean the lens because the lens is fragile. Insert the disc plate into the dvd player and press play, if it does not play try the second method. Ensure the cover of the player is open, connect the power plug to the mains socket and observe the lens if it beam a red light, Also check the ribbon cable use to connect the lens to the printed circuit board, then gently clean the lens with a dry cotton bud , insert the disc plate and press play to see if it play. If it does not play the disc, then this require a change of the lens

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.

Unfortunately there might no be a fix for this type of failure unless the LCD is open and perform a few measurements in the circuitry. Since the TV is less then a year old, I would suggest to contact the vendor or manufacturer to have it repair under warranty, most electronics devices carry one year warranty.
Let me know if you require further assistance.

No video on a 50H82 Toshiba Projection


If the screen is lit, then there is high voltage. If there is no video, and the screen is lit, then there is a loss of video. The fault can be anywhere along the main video path before it gets decoded in to the red, blue, and green compositions.

If the screen is not lit, most likely there is a high voltage failure, or there is a failure in the bias supply for the tubes.

When there is a loss of high voltage, this can be from any of the components in the high voltage area. Some of the main things that go defective are the flyback, high voltage multiplier, and various other small components.

Have you considered to replace the set with a good Plama or LCD set? This repair may end up being on the expensive side.
