Red Attention sign on screen

I have a TV that is setup in the operating room and we can change to different areas and view Xrays, heart caths and ECHOS from other areas. The problem is when the cath lab is pulled up live it gives me a red sign that says Attention The frequency signal is out of range. Please change the signal timing. Just below the words there is H: 77kHz V: 72Hz How do I change that timing?

Re: Red Attention sign on screen

Try this. The signal timing of the monitor is picky in the fact that it must have 60hz. Try changing the source of whatever is feeding that monitor to output 60hz signal. That should fix your problem.

I cant view my sky channel on my tv

So you want to view your sky TV in a different room?
You can achieve this a number of ways.

Purchase the multi-room package from Sky TV. This will give you fully independent TV reception in each room. (Basically two sky boxes)

Purchase a TV sender which will wirelessly duplicate the output on the TV to another device.

Connect your Sky box to a second TV with high-quality co-axial aerial cable connected to the RF2 output on the back of the Sky box.

How do I get sky from my set top box to work in a different room, I am trying to get my sky to work on a TV in a different room ? I have wired up TV coax cable from my sky box in sitting room and run

Hi Jim,
Here In my place in India, you can attach only one tv to the sky set top box.That too with AV cables. The program or channel changing is done by box only. The tv works as a monitor and has no role in program selection. You can attach a second tv to the box not through antenna cable but through AV cables only. That too if the box is having second set of output sockets. In that case both the TVs will receive the same programmes. To watch different programmes on the second tv you will have to go for an additional box.

I have purchased a Samsung Led 50 inches tv in USA, The picture is not displayed full on the screen. Can you please suggest?

These are generic instructions for all TV's and all Remotes:

1. Press 'Menu' key on Remote (or 'Setup' key).
2. Go to Setup, View, or Picture tab (whichever one you've got in your Remote's Menu or Setup)
3. Change your Zoom or View aspect.

NOTE: Depending on the dimensions of your TV, you simply may not be able to view the entire picture using a correct aspect ratio (NOT stretched). On my 42" RCA is use a 4:3 Zoom setting to fill my screen but, it chops a little bit off the top & bottom. It's the best I can do with my current setup.

Picture settings..? What are the best calibration

You can't use someone else's numbers, even for the same set, and expect them to be perfect. The picture settings are governed by the viewing conditions in your TV room.

Settings such as Brightness can only be set correctly in the room where you are viewing. Brightness affects where you might then set gamma, and contrast, and colour. So just one setting has a lot of impact on several other areas of the picture.

Putting in someone else's numbers will make the picture look different. But that's not the same as the "best" calibration for your TV.

If you want to do a good set-up without spending any money, have a look at your DVDs and Blu-rays for those titles with the THX Optimizer.

Remote not working as i moved tv into another room

If the remote control you've bought is a universal remote control, you have to set it with your TV, by TVs setup codes. The setup code list will be attached to the new remote controls' packing. If you wish to get more details, check the sites linked here. Set-up code list, and Set-up procedure to many popular brand remote controls are given. Selecting the view option, either to Mosaic / Timeslide, can be selected by the drop-down list, by the top left of the display window, will make surf easy

Monitor dims when we turn lights off in room.

You need to give a more detailed description of the problem.
The LG 47LH90 is an LED backlit TV with 'local dimming' technology. This means that there are lots of white LEDs behind the screen and these can be controlled in groups to allow localised areas of the screen to be dimmed to produce better contrast between light and dark. It is very likely that when the room is dark, this local dimming is more noticeable. The actual individual LEDs cannot be controlled and so the area that is dimmed will generally be greater than the area that is required to be dark 'blooming effect'. In addition, LED backlit displays only maintain their contrast through a tight viewing angle. If you sit too farto the right or left, then light from non-dimmed LEDs will leak through and the screen will look lighter.
In short, there may not be any fault with your TV.

How to install a home theater

Follow these steps:
•Plan out your setup. Before you start unpacking speakers and moving furniture, it's a good idea to have a placement scheme in mind.
Consider the location of the outlets in your home theatre room. If possible, choose a room powered by a single circuit breaker to reduce the risk of damage due to the overload your home theatre system might cause. Supplement the number of outlets with power strips.
Place your TV. The television should be placed where it can be viewed straight on. The center of the screen should be aligned with the eyes of a seated person.
Place your speakers before you start hooking things up. If there are hearing-imparied people in your household, place the speakers so that someone could sit directly next to at least one speaker.
Position your central channel speaker above or below your TV. If you put it on top of your TV, make sure the front edge of the speaker is aligned evenly with the front of your TV screen.
Place your front left and right speakers at equal distances on either side of your TV. The height of your left and right speakers should match the height of your central channel speaker.
Put your surround speakers at equal distances to the left and right of where you would normally sit and view your TV. Do not point your surround speakers directly at your viewing position. Try pointing them toward the back of the room or toward the ceiling.
Place your subwoofer to the side of the room, about halfway between your viewing position and your TV. You can adjust the bass reaction of your subwoofer by moving it closer to a wall to increase the bass, or by moving it away from a wall to decrease it.
Connect your speakers and theater system by running flat speaker cables down the length of your baseboard or lower portion of your wall. Consult your owner's manual for exact instructions.
