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?

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 have one of the old big screen tvs the hitachi rear view screen projector tvs I am trying to find a universal remote that would work perfect on it as we bought it from someone and didn't have a...


Generally universal remote controls won't work for all functions to any TV like its original remote do. Some functions may not differ, that is, if you try to up the volume, the tV's volume will go down, and so on. The most we can do is to try with other setup codes for the tV brand with the remote control, and synchronize it, check the functions, and accept a code which will give you most of TV's functions alright. I hereby attaches setup codes for Hitachi brand TV' both 3 digit and 4 digits. Try them, and see which code suits to your TV the most.
Three digit codes for Hitachi are: 001/ 004/ 009/ 013/ 059/ 061/ 079/ 088/ 091/ 137/ 139/ 140/ 141/ 142/ 143/ 144/ 145/ 146/ 179/ 210
Four digit codes are: 0088 0059 0142 0060 0072 0004 0009 0091 0001 0012 0061 0137 0139 0141 0179 0227

Direct Code Entry
  1. Press and hold the SETUP button until the red indicator stays on, then release the SETUP button.
  2. Press and release the desired Mode button (TV, VCR, etc.). The red indicator blinks, then stays lit.
  3. Enter the 4 digit code from the code tables. Note: after a valid code entry, the red indicator turns off. For an invalid code, the red indicator flashes.
  4. With your device on, press CHANNEL UP. If the device responds, no further programming is required. Note: If some buttons do not operate your device, try one of the other codes for your brand.

Code Search

If after trying "Direct Code Entry" your device does not respond, or if your brand is not listed, try doing a search of the code library for your code by following these steps.

  1. Manually turn on the device (TV, VCR, etc.) to be controlled.
  2. Press and hold the SETUP button until the red indicator stays on, then release the SETUP button.
  3. Press and release the desired Mode button (TV, VCR, etc.). The red indicator blinks once, then stays on.
  4. Press the CHANNEL UP button repeatedly (up to 300 times) until the device to be controlled changes channel. The red indicator blinks, then stays lit.
  5. Press and release MUTE to install the code. The indicator light goes off.
Most users will want to store VCR codes under the VCR button, Cable codes under CBL, etc. If you want to store a VCR code under CBL, etc., first follow the procedure for Direct Code Entry and press CBL in step 2 of Direct Code Entry, then enter ANY VCR code in step 3 of Direct Code Entry. Then follow the steps above for Code Search.

My IR remote no longer works in another room


Dawn,
If you want a remote that works via IR to control the satellite receiver you will need a IR only. The IR/UHF type only transmits signals to the receiver by UHF and the IR portion only operates the peripherals in the room such as the TV and VCR. There are some remotes that come with a kit that can change the remote to work as an IR only. I believe you have a TV2 remote and want it to work further away from the receiver particularly the room the TV is in. If this is the case you may have have to change the remote address of the new remote to match that of the old. You can do this by taking the number one remote and pressing menu-menu. Now take the new remote and press and hold the SAT button in the upper left of the remote until all lights across the top light up. Now key in the two digit number on the tv screen at remote address for tv2. Then press the pound sign and the SAT button will flash three times then press the record button and the TV2 icon should flash. Now you can cancell out of the screen on tv one and try the remote at the TV2 location. I believe this will fix your issue if not let me know. Thanks for using Fix Ya.

Setup Menu will not display on TV screen


Ok, on the back of the unit, there is a single yellow composite output. There may also be a Red, green,blue.Component. Take 1 RCA cable and plug it into that yellow output, and route it into your TV input, also a yellow composite. Make sure that whatever input you put that into on the tv, that you change the TV input to that to view your player. when and if you get a picture, you should be able to get to the menu through the GOVID remote.

Later once that Path is working, you can upgrade it to the Red,. green, blue, if your TV has the inputs. You did not give a model for the TV or I could tell you what it has.

If you need any more clarification, please reply.

Best Regards,

Charles

Suddenly cannot record DVD after years


Hi,

Apologies for the delay in response. Your concern was just brought to my attention.

To your recording, based on your second posting (and would appreciate corrective information where applicable), your system is:
  • Cable provider > Cable Decoder Box > Panasonic DMR-E75V > TV (equipment setup)
  • single coaxial cable > yellow, red & white > yellow, red & white (wiring setup).
With your indulgence, a couple clarifying questions:
  • to watch the Panasonic when you play DVDs, to what channel or source or setting must the TV be set to?
  • to record a TV program/channel, to what channel or source or setting must the Panasonic be set to?
  • what is the brand and model of your Cable Decoder Box?
Initially, pls try:
  • play any known good DVD disc/movie. power on the TV and set to watch said movie;
  • without changing anything on the TV, STOP the playing of the DVD;
  • try changing channel on your Cable Decoder Box's remote;
  • pls post back result(s); or
  • do the above steps again but before changing the channels on the decoder box's remote;
  • try changing/cycling through the different input/source of the Panasonic DVD;
  • again post back result(s).
Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards. Thank you for using FixYa.

Interference?


The picture tube on a TV can be magnitized by the Earth's magnetic field. The noise heard when you turn a TV on (usually followed by a static noise on the face on the TV) is called degauss. What this does it remove any magnetic variations on the tube due to things like the magnetic field and speakers. However, changes to the TV in orientation to the Earths magnetic field will cause the tube to have a magnetic bias. This is most prominent when turned 90 degrees. The easy way to clear this is to turn the TV off for a little while and then turn it back on. But remember that any movement once it is on can cause the discolorations to reappear. My suggestion would be to turn the tv after you've moved it to the location you'd like to view it.
