Hi, I,m a new member asking for advice about the following,
I have a Goodmans LD3266D LCD TV which faulted last night just as the football match started.
The blank TV screen stated "no signal" so I checked the arial cable at the TV end with my signal test meter and got a 70dB/uV signal strength given as "ok" I swapped the TV over with another TV (small LCD Goodmans) and it worked fine, so the fault appears to be in the TV
I removed the back to check that nothing obvious was amiss and every thing seems fine.so the question is where do I go from here?
Thanks for any assistance

Hello Paul (saban) I am back live again. It was the login problem
Just to update the thread having failed to get a signal through the HDMI connection I went into the TV direct with the aerial and got the same "no signal" response. changed the TV over with another one and got a good picture, no signal problem.
I have just tried again with the TV using scart and initially got a "antenna cable short circuit" message but that went off and I got a picture albiet poor sound, changed over to HDMI and picture and sound ok.
There is something wrong as the error message informs me but what would cause that error as I know that the aerial cable is good
Thanks again for the help

HI well ask him to check volt regulators on the main board as well if he wouldnt mind .
As you said it worked for a while then stopped working again, had the same problem on a set that if you unplugged it for a couple of hours it would work until you turned it off then it wouldnt come back on again until you left it unplugged for another couple of hours.
That was a regulator that caused it worth a check or as sparky said could well be a software issue

Hi,
I have resolved the problem, which wasn't really a problem at all
I started again from basics and found that I had sourced "TV" instead of "DTV" on the television
So I corrected that and re-tuned both the TV and the recorder and now have a perfect picture.
Could the fault that I had, have resulted in changes still taking place with the incoming RF signal at the time I lost the picture? as prior to that point I had no problems, and I changed over from analogue to digital last September or so I thought!!
Anyway, thanks for your input and I have learn't again that "back to basic's" is always the right option

Hi,
This TV is used primarily when I want to watch a program that my wife dosn't so I get kicked out of the lounge where the main viewing TV is and sent to the Goodman TV in another room so it isn't in use daily.
I think it was a number of factors coming together, it was ok.the last time I used it prior to the football match I wanted to watch but I presume it went out of tune. In the events that followed I ended up with it sourced on TV not DTV and as I said didn't revisit basics thus ended up on this forum.
I think the letter I was about to post to Prof Brian Cox about joining his team on particle physics I will put back
in the drawer for a month or two
Thanks again for the advice
