I have a ws-65511, it's been in storage for about 2 years. The picture is working fine but there is no sound. Digital cable box in hooked up properly with audio cables and Pr Pb video cables. Any ideas?


Here is somethings you can do/try.

Turn on tv and make note of any blink sequence on the power LED.

Verify you have no sound on any input.
Turn volume up on tv and determine if you hear any noise whatsoever coming from the speakers, in terms of hiss, hum, faint audio.

If you do here some sound, this points back toward your connection points where rust, or spiderwebs may be preventing good contact with the audio cables.


Depend on how you stored it, you could have had mice get into the tv and chew the wiring. Take the back cover off and inspect all the connections. Follow the wires coming from the speakers to where they plug into the board. Make sure the wires are not damaged

Look at the capacitors on the board and make note of any capacitors that have a buldge to them or the tops are rounded over. This is an indication they are bad.

Sanyo lcd projector has horizontal scrolling lines in its picture. Is this different than a lamp problem? Electrical? All else works fine. Thank you. Sanyo PLC-5600n lcd video projector. Not a tv.


This is caused by the processor and not by the lamp. As you might know, these projectors display colors by blanking out the light with lcd pixels. Most folks don't know that any display devices such as displays on cameras, laptop displays, etc. use an amazing amount of original technology that powered CRT TVs. (Yes, even vertical hold, although done electronically today, is there.) You'll just have to send this one in for service.

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.
