High pitch shrill when input device not DVI

When ever the TV is not on DVI, there is a high pitch shrill sound regardless of sound volume. Cannot watch DVDs since the input device must be changed to CMP1.

Use of silicon or superglue on a coil next to the flyback that solved the problem in a similar model RPTV. Easy fixes first

Constant high pitched shrill when turned on


Sounds like the evaporator fan motor bearings are shot and the motor needs to be replaced. This motor is found near the cooling coil in the freezer section.

Hello
VGA and DVI are not compactable. Your TV has no provision to connect it to computer.

DVI-HDTV Input (Input 1)

Use this DVI-HDTV Input for your external devices with DVI-HDTV output such as a Set-Top-Box, high-band DTV decoders, DVD
players and D-VHS with Digital Content Protection

1. Only DTV format such as 1080i, 720p, 480i and 480p are available for DVI-HDTV input.

2. The DVI-HDTV input is NOT compatible when used with a DVD player from a personal computer.

3. When connecting a Set-Top-Box with a copy-protect digital out terminal, a high definition picture can be displayed
on the screen in its digital form
OK.

High-pitched sound when using surround sound


I had the same problem, check your wires on the back of the tv and make sure your, red, yellow and white wires are in the correct holes. What kind of tv do you have, as I have an Ilo, and it has like 15 different plugs in the back, you may have to get you book out and make sure you have it in the correct hole on the back of the tv... I hope this helps....

Setting up receive set top box and tv for surround sound


Plug the TV to an open channel on your receiver via this output:
*Rear, 1 x Digital audio output (coaxial) ( TOSLINK )
This will look like a single RCA output plug.
Set that input channel on your receiver to some sort of virtual surround mode because it doesn't look like your HDTV has a decoder in it (meaning it will come out stereo and the receiver will have to fake it).
Turn the volume all the way down on the TV and use the receiver to control TV volume just as you do with DVDs.

*Substitute this with the digital audio output on your set top box if you are sending video only to the TV from the set top box (component, DVI or s-video connections). So video goes to the TV, audio to the receiver.
