SOURCE: blue screen with HDMI

The HDMI port might be loose on your TV. I had the same problem. I went to radio shack bought a solder and soldering metal with some flux. I then opened my 37inch Sceptre Naga and aligned the hdmi connectors properly to the board, I then soldered the hdmi port firmly into place. This fixed my blue screen problem.

Can not get a signal to my rca tv model led 32c45rqd


hmmm seems like the signal board is having issues or the cable your using is not good try having the cables or any type of cable replaced if HDMI or another source make sure the right input source is selected by changing the tv's input source (EG press the input button on the remote or "source" button)

I keep getting "no input signal". I have a small 32" Visio as a spare and it works fine using same cables, box, etc


try selecting the input source on your TV to the one you are using, sometimes auto-detect doesn't seem to work properly. This can be done by the remote control, or the buttons on top of your set.
You might also try changing the physical input socket, eg to the RF in, SCART, HDMI etc (you will probably need different cables for this), but if your set is selecting another source you will still get this message.
Also you might try using a different input device to check your TV, although this is unlikely to have any effect because the input devive plays on your second set.

Samsung Plasma TV has standby power but no video


Make sure your video and sound cable is working (rca, hdmi cable etc) and your source component like dvd player or settop box is working. If cable is plug into a socket AV 3 or HDMI 3 for e. g. make sure the tv is source or input is selected the same like AV 3 etc.

It is possible for the TV to switch on or off but no picture or sound. This means the input board or tv tuner is faulty in which case you need a good tv repair technician

When selecting the source, HDMI 2 will not highlight, Only TV. HDMI cable connected to box and to HDMI2 port on TV


You have to check the HDMI cable. In Samsung tvs the HDMI sources only highlights if the a proper HDMI sources is connected to the corresponding HDMI port of the tv. Also check by connecting any other device which have and HDMI connectivity to the HDMI 2 port.

How do I stop the aspect ratio from auto changing on my flat screen set up as the monitor for my computer?


When you set it to just scan the source will determine the scan. I would remove the bose from the unit and connect the cable or sat box directly to the hdmi in of the tv. if the problem persists check Samsung web site for software upgrade. If upgrade does not fix replace the main circuit board.

My sansung pn50a460s4dxza says it is 3d ready. how can i use this feature on my tv.


Your tv is a 2008 model, legacy 3d tv and requires a lot more than a current 3d HDTV does to view 3d. Today with a current 3d HDTV, Normally you only need a 3d source like a 3d Bluray movie and 3d glasses from Samsung and a HDMI cable connection from bluray player to HDTV. See below for your TV. You need a PC and IR emitter and Samsung 3d glasses plus user selected options on the tv.
Samsung 3-D Ready HDTV How do Samsung 3-D Ready HDTVs work?
Samsung 3-D Ready HDTVs are enabled by Digital Light Processing (DLP(R)) or Plasma Display Panel (PDP) engines that are capable of very fast refresh rates (120Hz). The inherent speed of these display technologies enables high quality stereoscopic 3-D by alternatively displaying left and right eye images. The display is synchronised with 3-D shutter glasses to provide the observer with a vivid perception of depth.
How do I connect my PC to a Samsung 3-D Ready HDTV?
The DVI output from the PC's graphics card must be connected to the TV's 3-D compatible HDMI port using a DVI-to-HDMI cable (or a HDMI cable plus a DVI to HDMI adaptor).
Alternatively, some newer graphics cards have a HDMI port instead of a DVI port. In this case, simply use a HDMI cable to connect the PC directly to the TV.
On all models, the 3-D compatible HDMI port is identified by the letters "DVI". (eg, "HDMI 3/DVI IN" or "HDMI 1/DVI IN")
What other equipment do I need to enjoy 3-D on my 3-D Ready HDTV?
  • Windows PC with DVI output
  • Compatible 3-D Shutter glasses and IR emitter with VESA compatible sync connector
How do I connect the IR emitter to the 3-D TV to support wireless 3-D shutter glasses?
The IR emitter should be connected to the "3D SYNC OUT" socket. The emitter should be placed on top of the TV with the LEDs facing towards the room. How do I turn the TV into 3-D mode?
Ensure that the TV source is set to "HDMI 3/DVI" (or "HDMI 1/DVI" for 720p models).
Plasma HDTVs Press the Tools button and select 3D Effect. Update from Off to Mode1.

HP PL4260N source list entries are all "Cable"


Video board is most likely damaged from a electrical spike, you may try looking at the capacitors on the boards inside the tv and see if they are damaged capacitors are an easy solution to problems some of the time.
