Hi all, 


I've got a 55" Samsung TV at home - not smart, a few years old now. Don't have the model # on me but can get it if necessary. 


Have been using this TV for Freeview|HD (built in tuner) for several years, (From Mt Campbell in Nelson/Tasman) and have had this ongoing issue ever since I've had the TV, in two different buildings now and with 2 different aerials/cables, and with a firmware update done on the TV, there was still no change. 


When the TV is first turned on, (doesn't seem to matter which channel) the picture will be totally broken up, no audio or glitchy audio, or sometimes will just sit there and say 'data service' for anywhere from 10 - 50 seconds, then come right. Once it's come right, it's perfect. It looks like a low signal issue to me, but when the TV is actually working, the signal info in the diagnostics area shows perfect for all channels (as it should be).


I have LOS to the broadcast tower, no trees in the way, a high gain phased array antenna and new cabling. Any ideas? I was half wondering if there was too much signal, would that be possible?


interested to hear any thoughts, or if anyone else has experienced this.

Thats what 2 of my set top boxes did before dying totally after about 6 months. Not sure why you would have had it from new tho. Suspected cause was capacitors being trash and needing to warm up as it was worse when it was really cold and would take 20 mins sometimes to deliver a stable picture.

Have you done a factory reset after the firmware update?

I had a similar issue on my Samsung, it was the capacitors in the power supply.


In all I think there were five electos and I replaced them with ones from Jaycar, I upped them from 85 deg to 105 or 1025 degree.


I dont suggest you change them yourself unless you know what your doing and are confident.


It was not hard but in saying that, I did my apprenticeship with TISCO in the late 80's but have not repaid TV's for over 20 years.





I know enough to be dangerous

Not 100% sure but I don't think so. Will try that.

Factory reset hasn't helped, thanks for the idea though. Think I will just continue living with it.
