This is a problem that is not likely to be resolved remotely. That being said, here are a few possibilities:

1) The video switching chip inside the set is defective and sensitive to heat.
2) The voltage regulator that controls the power to the chip is defective. (in essence turning off the chip)
3) The microprocessor that controls the whole set is getting confused (for whatever reason) and switching to another input stream without any indication to the user.
4) The dialogue over the HDMI tells the set that there is no video being sent/

The best thing to do here is to look for a pattern of when this occurs. FOr example, does this occur only after the set has been on for a while or is it immediate? Are other inputs effected in the same way or just the HDMI?

Keep us posted.

Your problem is in the streaming player. It is not keeping up and when an HDMI loses connection it will not auto find it again. To verify this take the Panasonic out of the loop and see if this fixes it. I love HDMI but it is touchy

2My Mitsubishi WD52725 displays a blue screen suggesting to check my inputs and says signal is invalid..checked all the connections and all is good there..any suggestions? Thanks in advance, Nick


What is your input source and which input cable type? If the source is a PC using a VGA cable, what resolution is the computer sending? 480x640. 800x600, 1024x768, 720x1280 (EIA standard) all at 60Hz are known to work but other modes might not.

If you are using a PC to the HDMI port, it will not work. The only HDMI ports that can connect to a computer will be listed as HDMI/DVI and this TV doesn't have that type of HDMI port.

If you are using any other input source, check try another source or channel. (One of my TVs intermittently finds a digital channel 25-9 and gives that message. We have no clue what station is being found but all the other channels are fine.)

I hope this helps.

My mitsubishi projection tv, ws55813, was losing horizontal sync intermittently, turn off and back on, sync was ok. turned off and back on, once too oftern, to solve sync prob and now I have blue screen....


There is a hard reset you can try on this set--it is done with the Mitsubishi remote that came with the set.

Confirm actual model number and I will tell you how to try it. The set will shut off after the reset(not the reset button some of these sets have on the front) and come back on channel 3 in the air band--any labels for inputs will be replaced by original input numbers etc.

No guarantee this will fix your problem but it will return the set to the condition it was when new in the box.

Let me know if you want to try this.

Turn on goes blue then turns off


The most common reason for a TV to display a blue screen with no picture is because the source device has not been set to the proper mode.

If you are using a cable or satellite set-top box, ensure that it is turned on and set to an active station. If the set-top box is connected to the television using a coaxial cable, then the television should be set to Channel 3 or 4 to receive the signal.

If you have are using a VCR that is turned on, but not playing a tape and not tuned to a receivable channel, then a blue screen will be displayed on the TV. To resolve this, turn off the VCR or tune it to a receivable channel. If a cable or satellite set-top box is connected to the VCR using a coaxial cable, then the VCR should normally be set to Channel 3 or 4 to receive the signal.

If the blue screen is not because of a connected VCR or set-top box, the TV may require service.

My Samsung LN40A530 only produces a blank blue screen whenever I try to use an HDMI input source. Audio seem to come through fine but not the video. Other, non-HDMI video inputs work fine. I've tried...


We are having the same problem. We have 2 DVD players with up-converter to 1080i and 1080p. Both DVD work fine (one Sony and one Samsung) with our Samsung LN-T4053H upstairs, never intermittent.

LN40A530 downstairs is having "Searching for Signal" problem. Took it back to Sears got a new one, problem followed. Something is wrong with this LN40A530. Perhaps firmware update is needed.

HDMI connection problem


On your TV set remote are you selecting the proper input; for example when you have different devices connected to the back of your tv set, dvd player, vcr, cable box etc; you have to tell the tv which device you want to use by selecting the right one on your tv remove input selection. Hope this was any help.
