Problem with hdmi compatibility with motorola fios cable box

While watching tv the screen goes black and no signal flashes on screen
I disconnect the fios cable from the back of the box and start up again and picture comes on. I spoke with Verizon today they tell me that the motorola box is incompatible with some tv's. I should contact you and ask for a firm ware update if thats available other wise they will provide a different type of cable hook up.
Have you heard of theis before and can you help me?
Thanks very much
Barbara Driscoll
the model # of tv is DP42746
When the TV is turned on, initially the picture is fine, then within minutes the screen goes bright green, but the audio is still present. Eventually the picture will return, but then will go out again and again. Replacing the HDMI cable with expensive component HD cables does fix the video display problem, but the quality isn't as good as HDMI. I'm very disappointed that the Verizon installer did not mention this when he connected my Sanyo HD TV.

Check your set up again. Mine says the HDMI/DVI is HDMI 1 (and then connect the audio to the video 3 audio input).

I need a magnifier to read the label on the TV. You just need the only HDMI input that has (DVI) in front of the word Input.

I hope this helps.

I have seen similar problems but not this specific one. I would say that 90% of the time the problems are caused by a dry joint (that is a soldered joint that is not connecting properly) on the power board. Dry joints almost always occur where there is heat, so the power board is the most likely culprit. Often inspection of the pins on the board under a magnifier will locate the joint.Your engineer if they cant find the problem should just replace the board to eliminate it as a cause of the problem, if it is under warranty.
I hope I have been of help but please do not hesitate to ask if you have any further questions.
I appreciate your vote if you appreciate my reply.

Hello, yes you should have no problem with picture quality the difference should be hardly noticeable. You should however buy good quality leads to make up for the lack of HDMI ( High Definition Multimedia Interface). If the Blue Ray only has HDMI output, you can get an adaptor from Tandys or similar. I hope that helps you.

I have a 42 inch led tv bought T Xmas

It usually matches the signal being sent to it. the movie etc. is 4:3
If you have a hi def cable/fios etc box you need the HDMI cable or the 5 AV cables to actually watch it in HD then this should stay at 16: other wise your stretching the picture makes people look funny
Hope this helps, God Bless :O)

The TV turns on but cannot find a signal (as has been normal when swictching to HDMI inputs). Usually it takes a second and the Cable or FIOS signal shows on screen. As of today, the images never comes...

Tries tv and cables boxes uplug,replug it back like about an hour later for the tv resetting itself back to the factory setting and those pay boxes updated it softwares.Take the HDMI cable plug it in into another tv HDMI hub.Tv should have signal and work again.

My hdmi port is not working

I have Verizon Fios and there's a known issue with the motorola HD boxes that they have bad hdmi ports, the screen goes green and that's it, nothing I can do about it I just use component cables. You need to be sure it's your tv not the cable box. Try the hdmi on a dvd player or ps3 or whatever else you have first just to be sure it's the tv at fault not the cable box. If you determine it is the tv you need to replace either the main board or the video board depending on your specific tv model. Some have the video inputs on the main boards some have video boards.

HDTV goes blank when connected to Fios HD-DVR or Fios DTV recvr.

If you can first connect the Fios box via component and that will rectify the issue and still allow HD. HDMI is funny, if there is anykind of communication issues between the TV or the Fios box you see what happens. You might also call Samsung to see if there is ANY firmware/software updated for your TV specifically to fix such an issue with the Fios/Mortorola connection. If there isn't then the issue is the cable box since the TV works ok on HDMI with other devices.

Tv goes off, then comes on, and volume goes to max

OMG! Verizon Fios at it again with changing boxes! Well let me tell you if you do not loose signal on a DVD using these same inputs ITS NOT YOUR TV!

Whats going on is further into Verizon system you loosing the signal from the VDSL slam outside in the pill box. This thing will need to be replaced and they are going to blame your TV until you just give up and buy a new TV only to figure out its not your TV.

1. Call them back
2. tell them to check there network
3. if that dont work tell them to check it again
4. if you have HDMI use that instead of the scart connections.

I hope you have luck with Verizon Fios there internet rules but there TV service is sub par!

HDMI crap out

I got the solution. Contact Customer Service, ask for LEVEL II Tech, and ask them for the old firmware. It will take a lot of pressuring, but they will send it to you and then it will work fine!
