I have Dish network. when I first turn the set on I get a "no signal" showing but have audio. After leaving it for a few minutes it generally comes on but then will go off when it so chooses. It comes and goes from picture to no signal with no particular pattern. Dish says it is the TV. The TV has not been moved and the cables have not been bothered with. This has been going on for over a week. What is the problem?

2 possible solutions, 1. If you have any type of dish network, go into the service part of the menu and check the signal strength usually a signal on any of the transponders less than 70 will cause this on some channels due to thier own signal. You can have either a tech come out,( sometimes for free, or you can adjust the dish very i reat very small increments so as not to diviate from the correct izmuth setting originally aimed at. to do this, you can do it yourself by selecting signal strentgh meters on the menu and raising the volume so you can hear the repeated blips while adjusting the dish. The sound your looking for is like the old Pong game on atari. The faster the blips, the stronger the signal. Slower blips mean your aligning the dish in the wrong direction.
2. Check your coax cables. If their old, they may not support the bandwidth being sent through it. Check at connections, ( All of Them) they wear with age. Is the cable itself at the connection protruding enough to enter the receiving female part. When you unscrew a coax at the connection, it should have about 1/8" to 1/4" copper cable past the connector and in clean, good, straight condition. make sure they are tight, and good luck
press services then system set up then signal test the signal strenth and qaulity should be about half way at least it shows up grey lock indicator should be ok if it shows not locked your dish has been moved and needs to be alighned do this when the weather is fine clounds and rain reduce the signal and may even stop it all together sky will charge you £65 to alighn the dish but you can buy a meter and do your self get 1 from bandq ebay maplins worth checking for breakes in the cable going from your box to the dish and if you can try your box on a friends dish just to rule out a faulty box of course there is a chance the lnb on the dish has gone faulty but you can get these cheap to or even borrow a friends to try unscrew the cable and look how it is fixed on useualy they just pull of but it might have a clip on or tape on
There might few possibilities:
Loose cable from the receiver to the diplexers, switches and LNB.
I would suggest to try swapping the receivers to isolate the possibility that one the receivers might defective as well.
Hope this helps.
NO - - signal did nothing to the set... Sounds like a shorted HOT (horizontal output transistor) and the feedback your hearing (chirp) is on the horz. transformer as it tries repeatedly to startup... Don't allow it to do that for too long...
Hi first of all are you using scart leads to plug into each device here is how it should be set up ok 1. Scart lead from dish network into vcr 2. then other scart from vcr into tv 3. Now ti recieve the signal from the dish network you need to have the telly on the right av channel so that its picking up the signal from the vcr. you can test this by changing the channel on the vcr controll or direct via buttons on vcr. If the channels change then your on the right av channel. Now when your on right channel on telly you need to now make sure dish network is on and on a channel or press the tv guide button just so you know what your looking for when the picture comes through. You need to press av on the vcr controll this will then pick up the signal from the dish network via the scart lead as av is the channel for scart lead. say if you was recording from dish net to vcr you would put the vcr on av to pick up the signal so press av on vcr controll this should then allow you to watch the dish network with no problems. Let me know if you still cant and ill assist you further if it dont work tell me what you have done so i know how much you have done ok
