Make sure input mode selector on the front is set to either analog or or digital. For example if the sound input from the dtv/cable is analog and you have it set to digital, you will get no sound. Change it to analog. This happens to me when using my crappy dvd/vhs player and I have a vhs playing (analog). Hope this helps...

Hi.

Plasma display suddenly dimming down is usually symptom of a faulty sustain board. Sustain boards and other parts like the PSU must be tested before replacing any component.

Hello

Your TV will display all High Definition signals as 1080i True HDTV™ and all standard definition signals will be displayed as 480p.

Component Inputs 1-2
YPbPr(480i/480p/1080i)
These inputs can be used for the connection of A/V equipment with component video outputs, such as a DVD player or external HDTV receiver. Please see Appendix B for signal compatibility.
Input DTV (480i/480p/1080i)
This input is used to connect an external DTV receiver, and can be configured for YPrPb and RGB plus H&V signal types.

As a special feature, you have the ability to adjust the red and blue light beams in reference to the fixed green light beam. This process is called convergence. There are two separate memories for convergence. One, for SD 480i/480p signals; the other for HD 1080i signals. SD convergence should be adjusted while watching an SD source and HD convergence should be adjusted while watching an HD source.

Wide Expand: Enlarges the picture, cropping some of the image on both sides. This Expand format is useful to remove or reduce black side bars on HD broadcasts of 4:3 images with black bars. Available for analog 1080i, digital SD 16:9 and digital HD signals.

InputDTV
This input is compatible with most standard DTV and satellite receivers with component video (YPbPr) outputs. Compatible DTV signals are SDTV 480i/480p, and HDTV 1080i. All other DTV signals, such as 720p, need to be converted by the DTV receiver to one of the compatible signal types. Please check the DTV receiver specifications before connecting.
This input is compatible with some DTV receivers using RGB with "separate H and V sync". Compatible DTV signals are SDTV 480i, 480p, and HDTV 1080i. All other DTV signals, such as 720p, need to be converted by the DTV receiver to one of the compatible signal types. Industry standards for DTV RGB signals (systems, synchronization, timing, and signal strengths) are not currently established. These inputs will not be compatible with all DTV receivers that offer RGB, HV outputs. RGB, HV signals with less than 5 cables are not compatible.
If your DTV receiver offers both DTV component video signals and DTV RGB, HV signals, we suggest you use the DTV component video signals. Check the DTV receiver specifications before connecting.
Ok.

Hello,
You can fix this, all that is needed is to carefully understanding the electronics parts used and having little of basic knowledge in electronics.
The problem is in either power supply or the Y sustain board. The Y sustain board is are relatively large board if out of which go connections to the side of the display , it therefore closer to either the left or the right side of the display , has at least one rather large heat sink on it and far power cables connecting it to the mains power supply .
Often there are fuses on that board , one or more , check them
If they are blown you can try to replace them, but expect them to blow again , usually the whole board needs to be replaced.
Often that need to be done in a service center as there are some adjustment to be made after replacement.

Dim Screen on the 2001 Toyota Prius


Yes the screen dims automatically when the lights are on to suit night driving. I am not specifically familiar with the 01 model, however on my 08 model, the display brightness is also manually adjustable via a button located below and to the right of the display. The button is marked with a series of short lines assembled in an arc. Hope this helps.

Sounds like your inverter or your backlight is failing. The inverter is an easy repair, the backlight can be replaced but it involves taking the LCD panel apart, The backlight comes installed on new screens. I can include a service manual below and possibly a generic guide to backlight replacement....

I can't scan DTV channels on my vizio 52''


do you have antenna or cable? if you have antena hook directly to the coax, go to menu, TV, tuner and pick antenna and scan. If you have cable hook directly to your coax repeat the previous step but pick cable instead of antenna. Notice if you have a cable box, you will not need to scan for channel since it will be on channel 3, 4 or any other input you may use.
