Check to be sure that the output from the laptop is within the supported range of the set. If it is not, the video input will not be recognized and the message you are seeing will be displayed.

I have an older 2004 or so philips hdtv projection tv with the built in tv stand. i want to connect my HD cable box but there are no hdmi ports. and i buy a wire with the VGA on one end and hdmi on the...


Get a component video cable (blue, green, red) and a separate RCA audio cable (white and red) if your cable box has a component video output and the TV has a component video input.

If your cable box doesn't have the component output, you will need a converter to go from the HDMI to component video. Something like this: http://www.hdtvsupply.com/hdmi-to-component.html . There are other converters available if your TV has some other inputs available.

A cable that has an HDMI M on one end and a VGA M on the other will not work. HDMI signals from the set top box are a digital signal. The VGA port on the TV is set to read an RGB analog signal. (Similarly a component to VGA cable would not work since the RGB and PbPrY are not compatible.)

I hope this helps.

How do i get 1080i, my tv shows im only in 480i. i think i might have it hooked up incorrect. my other tv of another brand is much newer so all i did was connect the hdmi cable from the tv to the cable box...


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.

Connect laptop to toshiba 50h8250


This requires a converter. If the laptop has a VGA port, use an VGA to component video or VGA to composite video converter. See this site for some examples: http://www.svideo.com/pctocomponent.html . Do not use a VGA to component video cable - these are meant for projectors that use RGB signals.

If the laptop has an HDMI port, you'll need a different type of converter, like this: http://www.hdtvsupply.com/hdmi-to-component-adapter.html . Then set the output to YPbPr.

I hope this helps.

(I doubt your laptop has a video controller that can output a non-RGB signal.)

Computer to HDMI outlet of Hitachi HDTV rear projector


The TV should be pretty simple. It is generally going to be HDMI 1, 2 or 3. If the TV won't tune to one then it doesn't detect a signal on that port. More likely, there is a setting either in your Graphic Adapter software or in Windows to output to this port. Windows doesn't turn anything but the RGB port on by default.

Hi my name is Roety,
I can help you with your issue ,
First of all lower the blue and any other screen controls or service menu settings back to where they were or lower.
Then see if it powers on again with a picture.
If it still shuts off, unplug the Blue CRT circuit board and see if it works.
If it does work the blue CRT may be shorted .
Your problem may have been corroded CRT pins.

I am trying to connect my laptop to the Polaroid LCD TV, as i would like to use the TV monitor as a computer monitor (my laptop monitor is broken). So I connect the correct wire to correct places, however...


The simple patch that I found (same problem) was to start by using any old monitor that I could borrow to set up my Dell Laptop.
After getting the Laptop booted on a regular monitor I right clicked on the desktop and went to properties then to the settings tab.
Here I found the dual monitor settings (#2 will usually be dis-abled by default.)
Click on #2 monitor and set the resolution to the lowest number (800 x 600 works well)
Then I clicked on "make this monitor my primary monitor"
As soon as I clicked apply the PC Windows screen appeared on the Polaroid TV screen

Earlier I had set the secondary monitor as "extend this screen to this monitor"
This also worked but I had to "drag the current screen to the right all the way off the
"borrowed monitor" until it appeared on the TV screen. The mouse pointer will be there also.
At first it took a little getting used to but in a few minutes I was up and running.
Hope this helps your situation
