There can be few suspects for this fault but ONLY a signal test will confirm the exact part.
1. It is possible that the TUNER is faulty , if so the AV must work with good clarity.
2. Also the IF section can be faulty, it can be the IF processing section or the data switching from the processor.
3. It can be a digital logic gate switch failure as the processor is unable to switch from AV to the TV RF section.
4. Tracing using a signal or tracing with a scope can confirm the section. You can check at the AV switching section for a possible fault.
You must apply a clean signal and see that the picture is clean if not the TV tuner section is faulty.
If there is snowy picture then the input RF section , the TUNER section and the VIF/SIF section must be checked.
There is not much in the menu than to use a fine tuning to have a clean picture.Otherwise the tuner is a suspect.
two ways of connecting VCR with Analog TV with DTV tuner. DTV tuner (RF) output to VCR (RF) input,VCR (RF) output to analog TV (RF) input. turn DTV tuner on (VCR should have a TV\VCR switch that makes signal coming from tuner BYPASS VHS right into TV) note:: change channel FROM tuner.You should be able to record by placing a blank tape and pressing RECORD. 2ND. DTV tuner, VCR, should have a RCA in\out connections...Audio & video.You need a RF\RCA bypass switch. It has a INput with RCA connections to a RF signal out that goes to the RF Input of analog TV
actually you dont need the tuner you just need the rf connector itself which you can easly pick up at a radio shack for a few bucks. you can DIY it will take a bit of soldering and time. First take the broken connector to radio and look for a close match, longer leads better you can always cut to fit.
remove board from tv and un solder the tuner. if solder does not seam to melt apply some fresh solder and then unsolder. pop the tuner lid of carefully both top and bottom to gain access to the circuit. cearfully remove any remains of the old connector. Now find the hole where the last part was and insert new RF connector adjust and cut the lead if nessary and resolder to circuit. place both caps back on and resolder tuner to board.connect board to ther circuit and test.
First off, scart has an auto detect feature across pin 8, HDMI does not. If you have turn your TV to the HDMI channel, and at some point turn off the HD source device you are going to get a blank screen, you have to manually turn your TV back. In regard to whilst you are recording it sounds like you may have tuned in channels on your DVD but not your TV. Do you have an RF aerial lead connected from the DVD output to the RF on you telly? Do you have a sky/cable box connected to your TV via scart? Does the DVD have DVB (digital video broadcast) if so and you have none of the above that is the problem, any tuner running off a single RF lead can only record/play 1 channel at a time. If you have no RF lead going to the TV, then the TV cannot show any terrestrial channels.
nip to the website and ask them as you don't give much detail on connection side some use rca connection others use scart connection and others go through rf leads to tv.
on samsung always try manufactures webpages before coming here some solutions we find are posted on the company who built the pruduct others are from experiance from having product itself.
sorry for not helping on this one it may be the vcr out picture tuner has gone may be another factor.
This usually a problem on/near the horizontal section of the TV board caused by solder that losses its contact thats why you need to bump it sometimes for the picture to come out. To remedy this just try to resolder any parts that you suspect seems to loose especially in the part where the components tends to get hot when operating, this usually are the horizontal section or the power supply section which is very common.
