I recently moved the location of my tv into another room, however, to get it to go where i wanted to i had to use an extension cord. This extension is a multi-plug real type with a 3amp fused plug. While watching Sky sattelite TV both units turned off instantly. I presumed fuse, so i swapped it over. The Sattelite receiver turns on, as does the tv but there is no sound or picture. It has had a brand new tube fitted 8months ago or so. it simply wont power up from standby to on... it trys, but then flicks straight into standby again. Is there an internal fuse too that may have blown? the problem is that the 3amp fuse would've blown earlier than say a 15amp one so i cant see a power surge causing damage being an issue?

Make sure the cable you now have hooked up to TV is actually hooked up to the dish. If you're sure it is then take the TV back to original location and hook it back up. If it works in that location you have a bad cable. If it still doesn't work it's the TV. The only other thing I can suggest is that some TV's must autotune before a picture can be shown. If you're sure you have a ggod signal go to the TV menu and do an auto tune or auto search. The TV will then go thru all the different possibilities looking for signals. Once it has completed the search it will then give you a picture. You can then go and add/delete channels and set it up however you want.
The TV is in protection mode because of a fault with moving it and then coming on briefly I would suspect that the fault is a dry joint ( a solder joint which has fractured) finding it can be time consuming but it is most likely to be around the caps in the line output stage which need resoldering.
The picture tube on a TV can be magnitized by the Earth's magnetic field. The noise heard when you turn a TV on (usually followed by a static noise on the face on the TV) is called degauss. What this does it remove any magnetic variations on the tube due to things like the magnetic field and speakers. However, changes to the TV in orientation to the Earths magnetic field will cause the tube to have a magnetic bias. This is most prominent when turned 90 degrees. The easy way to clear this is to turn the TV off for a little while and then turn it back on. But remember that any movement once it is on can cause the discolorations to reappear. My suggestion would be to turn the tv after you've moved it to the location you'd like to view it.
Try th set in another room, if only to see if this phenomenom happens with other light fixtures or appliances. Would suspect the switching type supply in the TV as suspect if the problem "moves" with the set....accordianman
yes i beleive you some stuffs do have a feeling. anyway, the symptom is usually caused by a breakdown in the power supply circuit. in most modern receivers (transistorized and/or ic), it may also be caused by a breakdown in the horizontal deflection circuits (hor. oscillator, pre-drive, or drive circuits). supply voltages for the tuner, vif,sif, and vertical output are usually supplied by the horizontal output circuit. but if you doesnt know anything about these stuffs, better bring it to a qualified service tecnhician.
