My 65 Samsung TV as no signal whatssoever. I tried HDMI and normal TV aerial, no signal. TV searches for signal, but does not lock onto signal. What do I do

That's because there is no signal :>D

Unless you are using an outdoor aerial on the roof and the signal via a aerial cable, your signal is not provided by 'Channel Scan'. In most homes, your television comes from a Cable Box or a Satellite box. The signal from those is fed to the television via an HDMI cable. On your remote, find the Source Button and scroll though the HDMI socket inputs.

TV Says NO SIGNAL - What To Check - How To Fix

Jan 14, 2016 - If it is just one TV that is showing the NO SIGNAL... -Be sure your TV is on the correct source or input as your CABLE or SAT BOX. -Press the TV ...

You need to try and isolate the piece of equipment which is causing the problem.

You've already tried the aerial lead direct to the TV and this is OK.

Disconnect all scart leads and try the RF on its own.

Try the Aerial lead to video, then video to TV.

Try aerial direct to Sky box, then to TV.

Try just connecting the RF out from the Sky box to the TV (no aerial input), can you tune into a good channel 68 picture from the Sky box.

Then Try the VCR to the Sky box (no aerial input), see if you can tune into the VCR and Sky channel.
Hope that helps.......

hey, when connect any aerial in the back of the TV make sure you have a look for the name of the connection you use ( Skart,ext1,ext2,usb,hdmi1, hdmi2 etc.) so you can do a search on that extension. if you connect something on Hdmi1 and search on hdmi2 you won't find anything. you have to search on Hdmi1. PS: good luck.

Press the TV/DTV button to make sure the TV is using the Freeview tuner.

Check your leads. Make sure the aerial plug is still connected. Go outside, have a look if the aerial is still up.

Well, there's your answer then. You have poor aerial signal so the TV cannot lock on when tuning. You need to sort out the reason why there's "Poor or No Signal" You need to fix the aerial, not the TV. I would have thought that was self-evident, surely?

What kind of aerial are you using. Do you know it works? Check out the aerial cables for breaks or badly fitted connector plugs.

No signal means that some external source (aerial, HDMI input, AV input) isn't providing a signal.

Your TV plays a CD okay because that is built-in.

Try connecting an aerial feed and tuning the TV.

perform an "auto-detect" if you are using hdmi interface, try a new cable. other than that, contact samsung.

sig strength 29 is too low to lock onto. Humax needs 50+ to lock ideally 65+

is the aerial ok? try the set on someone elses aerial. If no joy then its possible the tuner is duff...but thats virtually unheard of.

Do a first time installation, move the TV or bite the bullet and either buy an external aerial or extend the main house aerial cable to reach the TV. assuming your TV has no signal where it is now

first of all you would need to have a Sky HD set top box.

The cables coming into the wall.. you said one was the terrestrial aerial and the other was a sky cable. In order for you to benefit from Sky HD you would need twin cable or two single cable running from your sky dish.(allows you to record a program and watch another etc.

summary:
skyHD box
two feeds coming from your dish,
there is only one place these can go as they are screw on ie F connectors. so they would screw onto input 1 and 2 on the back of the Hd box.
Run a HDMI cable from the back of the sky box from the HDMI port to one of the HDMI ports on the back of your telly. last but not least you would need to get a power cable (kettle plug) to power the thing.

In regards to your terrestrial aerial you can plug this directly into your telly or via your aerial in port on the back of the skyHD box. then you would have to run an aerial cable from the RF out 1 or 2 to the back of your telly this would allow you to record two things on your Sky HD box then switch to your built in freeview that your telly has.

Hope this has answered your questions
