Hi and welcome to FixYa,

Initially, the displayed message "No Signal" indicates just that, there is no intelligent signal being received. This could be through the Cable/RF/ANT INPUT or through any of the video/auxiliary inputs. This could however, be also interpreted as that the incoming signal is not compatible with the system or within its capability. Example would be an incoming video signal with a high resolution above and beyond that of the TV's.

Might you post back with the brand and model of the TV as well as the signal source that activates the "No Signal" error/message.

Just a start, do postback how things turned up or should you need additional information. Good luck and Thank you for using FixYa.

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.

WILL THIS TV ACCEPT THE NEW DIGITAL SIGNAL


Hello. All tv's accept the new signal. If you get your signal from satellite or cable, the box will make the signal compatible with your tv. IF you get your signal from an antenna, you may need a converter box, available from places like radio shack and staples.

Unstable signal on a SONY KDF-50E2000 08760591


Can you please explain what you mean by an unstable signal? Without details, the problem can be anything from a weak signal being presented to the tuner to a defective tuner to poor signal processing later on. Also, check the picture and sound using different inputs to the set. If hte problem is the same regardless of hte input signal, that tells us that the problem is in the video signal processing circuitry. Also, place a menu on the screen. Is the instability present with the menu display?

Thanks,
Dan

No signal and theres signal


sounds like you need a new tuner replaced or the ssb(small signal board) inspected. The tuner recieves the cable signal and converts it into an intermidiate signal which in turn the ssb processes into audio and video signal.

Picture with signal applied is purple and distorted/choppy


The board you seek is the doubler (2HDW) module.. a lot of time reseating the board will solve the issue. If HD still works, this board is likely you problem. This board upconverts all non HD signals to hd to put onto the screen. IF HD doesn't work, you more likely need a signal board. This board has all the settings on it and is much more difficult to replace.

No Signal


Without more specifics it is difficult to tell what the problem is. I assume you are saying that the problem is you have no signal getting to your tv. If that is the case, first try another tv to see if it can see the signal. If the second tv does not see the signal then the problem is not the tv, it is the signal. You should look into replacing wiring or talking to your cable or satellite company about the signal loss.

It seems to me that you are watchin an analog signal on a digital HD TV, the analog signal is has a standard resolution of 720x576 for NTSC (American Signal) and 720x480 for PAL (European Signal).

It could be worth to go contact your cable company, they can hook you up with a digital receiver which gives a better signal and might even have a HD Signal (this means it has a HD-Ready 1280x720 of Full HD 1920x1080 resolution).

If you really want to use your LCD TV on his max this is really worth considering
