Repairing a CRT TV

Ratboy

I have a top of the range CRT TV, £1400 when new, a few years back...but it has lost the green in it's colour.

I've rung many TV repair shops, but they say, we don't fix them anymore.

I find the pictures from LCD/Plasma are poor, compared to top of the range Panasonic, and it's not the tube thats faulty.

LCD/Plasma are only designed to last for 5 years max....so shame on you! CRT...last forever! Unless the people that fix them give up.

It's a Pana Euro 4 H chassis

There apparently are some who will repair crt tvs. If you search online for - crt tv repair - you may find one near you.

I think that's a little optimistic. I think they generally lasted about ten years. There are always exceptions, of course.
Although there are still people who'll fix cathode ray tube televisions, the problem these days is sourcing spare parts for them. Since manufacturers no longer produce CRTs, it's going to be quite expensive to fix yours unless your repair can be done with a soldering iron.
I think you're very soon going to have to accept the limitations of flat panel televisions.

I repair CRT TVs, not sure where you are located but you will need to deliver and collect it from here in Bracknell. Loss of one colour may be something other than the tube but there is a very strong possibility it is indeed the tube and that would make it a write off. Spares availability is not a problem, but replacing tubes has never been financially justifiable and is something I never ever do.

As #4 says it is more than likely to be another component other than the actual CRT. Maybe even just a dodgy joint that needs twiddling. CRTs last for ages..just like older gas boilers do !

It could be the electronics rather than the tube so do not give up hope.

What you need is an engineer capable of fixing it, the circuit diagram is very likely available on the net given the exact model no.

Many of these Panasonic sets were fitted with Philips tubes (despite a Panasonic label on the tube itself) which suffered high failure rates, typically giving exactly the fault you describe. I have seen lots of failed tubes, they certainly do not last for ever. It could also be a fault in the pretty complicated video processing that these sets use, all contained in custom chips which if still available are going to be very expensive.

Bear in mind that post digital switchover you can only use these sets with an external freeview or satellite box. And they are not HD sets. Probably better to bite the bullet and buy a new set.

If it "lasts forever" why has it "lost the green"?

Would you ever have imagined having this conversation, even just 10 years ago. CRT TVs a thing of the past and is there anybody left to repair them?!
I always said I'd never have a flat screen TV but I gave in and now couldn't imagine a big old telly in the corner of the room.
I do agree though that the big plasma / LCD screens, combined with digital multiplexing/compression make for a much worse picture than we used to enjoy with a decent analogue CRT. I've just got used to it now.

You don't have to replace it with a flatscreen though. Still plenty of good CRTs being given away on Freecycle or sold for a few quid in the charity furniture shops.

LCD and plasma last 5 years max?

Ours is 6 years old and still going strong.
