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.

My vizio is blinking back and forth from the blue no signal screen to the actual hdmi input screen which is connected to a cable box. What is going on?


Have you tried a different HDMI input? (If available.) You may be able to test the cable box of PS4 using component cables to confirm that all but the HDMI is not working. You may try pushing or holding the HDMI cables to see if you can make the problem better or worse to identify a possible flakey HDMI socket.

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.

If the tuner is bad, changing the mainboard should fix the problem.

Sony bravia intermittent sound


Yep, same problem with mine. After many trial fixes, I discovered that it's the HDMI connection. I tried two different new HDMI cables in two of HDMI ports on the TV, but still got intermittent sound. The only way I solved it was going to component cables (RGB) with a separate audio cable. Works great now. Other Web sites say that HDMI connections do not always electronically "handshake" well between devices. Not sure how this HDMI problem can be permanently fixed, but using the component connection works fine.

LG LCD HDTV 'NO SIGNAL'


To fix the problem, try turning off the TV and unplugging it from the outlet. Once unplugged, push the power button and hold it down for 1 minute. Then turn the TV back on and rescan for channels.

If the problem persists, contact LG customer service immediately as there is a problem with the memory card. The device is unable to retain scanned channels for immediate feedback.

All LG LCD automatically comes with a 1 year manufacturing warranty. You would have to provide proof of purchase to show when it was purchased. Hope this helps. The Guru
