Threr is a manufactorer's fault on the product. take it in if only it is under warranty and you will get a replacement. I used it before.

Good luck.

What I find is a blown fuse, a shorted regulator i.c. and possibly a blown bridge rectifier(diode array). On rare occasions you can solve this problem by replacing only the fuse, but if the fuse blows when you plug the set in, you will more than likely find above mentioned parts have failed. The best thing to do is to call a repairman but if you have an ohm meter you can test it yourself:1.Unplug set and remove rear cover.2.Get spotlight and look closely at where power cord connects to circuit board.Small glass fuse will appear black if open usually.Otherwise,test for continuity, or just replace it.3.After replacing fuse plug power cord back in while looking at fuse.If you see an instant flash, fuse blew again meaning you will need to obtain parts in power supply and solder work will be required. That is probably as far as I can take this other than saying that you might first want to look at underside of circuit board to determine if major surge damage has occurred. If it has you will immediately know because it will have burn marks all around a/c power supply. I hope this helps

Dish remote 2 changes channels on both tvs and dish remote 1 changes channels on both tvs


Is the receiver in dual mode? Go to the receiver, open the door, and hit the mode key. If both TVs are still showing the same thing, then the issue is not the mode.

Go to TV 2 (the one without the receiver) and make sure the TV is tuned to channel 60 or 73. If it is still showing the same thing, go to TV1 (the one with the receiver) and hit Menu, system setup, Installation, modulation (menu 6-1-5). make sure the modulation for tv2 matches which channel you put your tv2 on.

Still showing the same thing? check the back of the receiver, the RCA cables (red/white/yellow) are plugged into the TV1 ports not the TV2 ports.

Showing different things but the remote still changes channels on both tvs? Go to TV1, hit menu twice, near the bottom there are two boxes each with a number. This is the address for each remote (tv1 and tv2). On the TV2 remote hold sat until it stays lit, choose a number different than on the screen, touch pound (#), the sat light blinks three times, hit record, the number on the screen should change to match the one you typed in.

Still being silly? Call a priest, you have a poltergeist!

Lights turn themselves on and off


I have seen conditions of poor / missing ground, high humidity and nearby two way radio operation (CB, Ham, Police, Taxi, etc.) cause unattended operation (on and off).

Make sure the switch surfaces are clean and dry. Try changing metal switch plates to plastic / nylon (and vice-versa) types.

Ensure that the switch is grounded. Before removing switch from box, shut power OFF. Carefully pull the switch from the box and make sure the switch's ground wire is connected to the ground conductors in the box.

Ultimately, if you are unable to solve the problem with these true touch dimmers, changing to a rotary knob / slide operated dimmer or even a standard toggle switch should work without incident.

I hope this helps and good luck!

My television set is stuck on one channel....the audio changes with the channel but the picture stays blurred on one channel...whats wrong with it?


Lots of possibilities. If you are using the remote, try also using buttons on the TV to change channels. If TV buttons work, the remote is broken or perhaps try changing batteries and cleaning battery contacts on the remote. If neither work, lots of other things to try. You may need to set preselect channels, so your TV thinks there is only one channel out there until you do. If you are on a cable box you just need channel 3 and change channels on the cable box. I can't tell what you mean by "audio changes with the channel" ... if you mean that when you try to advance channels, it increases volume and moving down in channels lowers volume that would be strange -- if you are using a programable remote it might not be set correctly (try another programming code). The "blurred" picture is probably symptomatic of having the set on the wrong channel, and if you could set channel it might clear up ... I'd start with getting channels to change. If you need more help, give the brand and model of TV, say if you are using a remote (original or programable), and what the 'audio changes' comment means in more detail. Probably worst case is that your tuner circuit is fried, but don't assume that without more diagnostic.
