I have a 28" Bush TV which has stopped working after being disconnected from the mains for about 30secs. Now there is just a continuous clicking but no picture. Has anyone any idea whether this sounds serious? Also any ideas why my DVD player will only play in black and white on my older spare set ?
many thanks
PS I know I should be on some TV repair newsgroup but I'm sure someone here will be able to help!

Many non-compatible TV sets will only display in B&W but I think there might be a couple of work-arounds...
How many scart sockets does it have - if two, try the other one, usually only one is fully wired per uk.media.dvd :-p
Failing that, has the DVD player got any output options - try changing the signal out, and see if that helps (ie. composite or whatever)
Not playing a region 1 DVD by any chance? If you play a NTSC encoded signal into a non compatible TV you will often get this problem.
Is the DVD output (check menu) set to S-Video rather than composite? S-Video into a composite only SCART will give monochrome.

RGB or Composite would be hard pushed to give a B&W picture but S-Video can do it.
Lol. Never neglect the obvious.
I went to a computer fair yesterday for a scanner. I came back with a DVD player (like you do) of the type that plugs into TV's. I had assumed I could plug it into the PC as it had a monitor connection outlet. Needless to say I have no speakers for it. I spent the rest of the day gnashing my teeth. I could have got a surround sound set for £15 to £20. Now it's going to cost double that or wait for the next fair.
(I just thought you all might like to know.)
Don't think there's any such thing as an NTSC or PAL DVD.
Dunno about computer DVDs, but most computer CD decks have an analogue output for the audio, and usually supply a lead, although the plug wouldn't fit a TV.
Why would 'Composite' (CVBS) be hard pushed to give a B&W picture?
Power supply failure.
My trusty Toshiba did that a few years ago, hoiked it along to the repair shop and it was basically a load of dry joints on the PSU and flyback transformer....

Oh yes there is.....
Please explain?
Region 1 (USA) DVDs are NTSC Region 2 (UK) DVDs are PAL Dunno about the other 4 regions
Sone DVD players convert NTSC discs as PAL output signal, others do not. If the TV doesn't support NTSC (many older ones don't) then the result is a black & white picture.
(Re-formatted so it's possible to *actually* follow the thread)
No they're not
Neither are these.
Well, there's SECAM etc...
I'm not talking about the players, but the discs.
HTSC and PAL only refer to composite analogue signals in this context.
DVD makers incorporate a regional coding in the discs to stop (mainly) US material being played in the UK etc. It's got nothing to do with NTSC and PAL, as the DVD system is digital and doesn't use them.
Sorry but this is incorrect, the information on the DVD is digital, yes, but when it is fed into a TV it is analogue.
DVD's can be PAL or NTSC (And maybe other formats too)
There is a fundamental difference in the video signals
Video is made up by showing a series of still images at a certain speed..
PAL is made up of 25 frames, or images per second, with 525 scan lines NTSC is made up of 30 frames, or images per second, with 625 scan lines The DVD has to be either one or the other!
If a TV cant synchronise to this faster frame rate, it seems to show 25 of the 30 frames per second in black and white
Also, as PAL is only 525 lines, I am guessing the colour information is cropped off the top (or bottom), as NTSC has an extra 100 lines of information in every frame.
Agreed.
Thanks!
Just a small point, when you reply to a post, it is common practice to place your reply at the bottom of the last post, snipping off any stuff irrelevant to the current post - it makes reading the conversation everso slightly easier for other people!

only bought the player from a computer show last week I had not studied the setup page. Now set vid o/p to RGB (was S-video) set to PAL and pic mode to Auto and guess what .....colour appeared !! These are not original discs I'm trying but the player seems to play anything I have. It's a 'Digital i' if anyone else has heard of it - £49.99 seemed a bargain.
What exactly is 5.1 sound? the speaker sets from the same stall were about £70 surely they are available cheaper? someone above mentioned £15. thanks, Mike
