Question about Panasonic PT-52LCX65 44" HDTV

1 Answer

HDMI Signal gone

My Panasonic PT-52LCX65 works fine with Composite and Component inputs, but my two HDMI ports no longer work. The TV seems to work fine displaying the HDMI setup, but no picture from Cable Box, Playstation 3, or DVD Player with HDMI connections. Any ideas?

The HDMI interface may have suffered a malfunction, this offten happens due to stray voltages on the ground plane. If you do not have electronics experience I would suggest taking the set to the shop and having it repaired

My laptop doesn't have a HDMI port so I have to connect with two cables...I think ones VGA and the other is audio. This goes into the back of my old smaller tv...which is ok but I'd like to route the


Your TV doesn't have video output on either HDMI or Composite video. (There are a few TVs that do have a video out but often that is only available for some input/output combinations. You would need to check the manual but the PC input is usually not available for the video output.)

You could get a VGA to composite or component video converter and direct the signal to your new TV from your PC. One example of the first converter is here: http://www.cablestogo.com/product/29548 . An example of the VGA to component video is here: https://sewelldirect.com/audio-authority-vga-to-component-pc-to-hdtv-converter.asp . There are other models available. A few VGA to HDMI converters also exist. However, since those need to convert an analog output to digital, they are more expensive.

I hope this helps.

(A few VGA to composite cables exist. They will not work for your purpose. They are designed to connect projectors with RCA ports and understand the VGA RGB signal to a computer.)

I have a zx4800 touchscreen gateway and i want to conect it with the tv is it possible ?


You may be able to add a second monitor. You need a USB video adapter to get an external video port. There are no external video ports on the ZX4800 all-in-ones. Here is an example USB VGA adapter: http://www.newegg.com/Product/Product.aspx?Item=N82E16812225007 . DVI and HDMI versions also exist. These aren't the greatest solution so don't use them for gaming.

These will work if the TV has a compatible port. If your TV has VGA input, you are fine with this option. If your TV has HDMI inputs, you need to check the specifications. Some TVs have HDMI ports that do not interpret the signal from a computer. If your TV only has composite or component video inputs, you will need a converter from VGA (RGB) to the TVs input. (Component is YPbPr.) One option is http://www.ramelectronics.net/product.aspx?zpid=3294 . VGA to component video cables do not work; those are meant for projectors that understand the RGB encoding.

I hope this helps.

TH-50PX77U inputs


Many times a computer's post screens will not show up a TV set, and once the computer itself has loaded the drivers and settings, the set may need to be shut off and turned back on for the HDNI or PC signal to be detected.

It is also possible the settings you selected for display properties cannot be displayed on the TV.

As far as the component video signal, are the connections correct? Sometimes people mistake the composite red, white and yellow for the composite system that divides the red, blue and green video signals.

While also possible, but rare- there may be poorly soldered connections on the "A&D" board (logic board) .

Panasonic PT-AE2000U All three HDMI Ports stoped working. I have tried different HDMI cable and a three different HDMI Feeds. I can get a picture using the red green blue component cable. Any ideas?


WOW. I just experienced the same thing. None of my HDMI ports are working, though component is fine. I've had my unit since November 2007 and had no problems until this. I think the HDMI board has gone bad and will require replacing.

RCA HD52LP: Composite video inputs don't work


RCA Authorized service tech looked at it. He determined that the DM Module need to be replaced. The part alone costs $550 + labor. Since the HDMI and component video inputs seem to work, he suggested buying a VCR DVD combo with HDMI output which would be far less than repairing the tv itself. I'n researching the possibility of purchasing the part myself.

Picture from analog tv signal is not sharp


I have this same machine, you did'nt mention what input you are using (composite, S-Video, component or HDMI) or what type of display you have (CRT, LCD, Plasma etc.).
If your T.V. has a HDMI input I recommend using that, if not and it's of fairly recent vintage use the component inputs (not to be confused with composite video inputs, or yellow RCA-type input).or at the very least use the S-Video input.
In the setup menu (on screen) try setting the "TV Screen" option to the 480p setting and if you are using the HDMI input try setting that to the highest resolution your T.V. has or set it to "Auto"
Finally in the on screen video menu select the "Video" setting and set the "Still Mode" option to automatic, and the "Output Level" to lighter or darker whatever your preference is.
Remember...Always use HDMI or component video inputs on your television (if it has those inputs)!
Hope this helps!

Panasonic pt-52lcx65 picture problem


Have a sears technician come over ,call them and set up an appointment, they are the best techs out there for tv issues, they will come out even if you did not buy the tv from them. Most of the Sears tv techs come from Philips which closed down their tech shop a while back. It sounds like you have dirty or faulty fans on your board. please advice.
