Question about JVC AV-27230 27" TV
What does this mean when displayed on tv screen. Is there and easy fix?
Please advise . Any info would help this novice. TV is in area of Scotland which has weakish tv signal
You should check the coax cable between the receiver and the LNB on the dish. Assuming that you can get to the dish, disconnect from the LNB - the connection will probably be covered with tape. Disconnect the cable from the receiver end. Examine both connectors and make sure that there are no stray bit of copper causing the short. With a meter, test the resistance between the centre pin and the outer screwed sleeve. The resistance should be very high. > 100Kohm. If it is a short or only a few ohms, you will probably need to replace the cable. If it varies the cable may be water logged. Damaged cable is not worth repairing even if you can find the problem area. Where I live, a bit further south than you - squirrels like to eat the insulation - and finding the damage is a waste of time. You can probably use the original couplings but don't forget to cover them with self amalgamating tape after you have checked your repair.
Hope this helps. If you are unsure or not happy about ladders then leave it to an aerial rigger.
