I've never seen (or heard) of a set you can switch between them - just go to a shop an ask to see what they have.


I've never heard of any 'radiation scares' or any bad 'motherboards' - in fact I've never heard the term 'motherboard' applied to a TV set?.

On any CRT TV set there is a slight possibility of x-ray emissions from the front of the screen (which is basically how x-ray machines work) - this can happen if the EHT is too high - and sets have protection circuits that shut them down if this happens. European sets tend to label this 'over volts protection' (or something similar), but the Japanese label it 'xray protection'.

Thanks for your help Nigel.

Apparently such sets are available. See post no 2. in this other thread of mine.

I was hoping to go the ebay or classified route, so it would be useful to know which models can switch, among other things.




I understand the principle of electromagnetic radiation being generated. However I definitely came across a report on supposedly excessive radiation from certain Sony sets. It could have been one of the "phone masts give you cancer" type stories though.

I also found a forum ( I think it was actually a Sony forum) where an engineer was giving someone advice on how to repair a Trinitron. He said something on the lines that it could be just a simple component which could be faulty, but that there was a particular model known to often have a problem with iffy "MBs"of a specific ID number, which might necessitate "taking out the whole MB". I assumed "MB" meant "motherboard".

Probably 'main board'

In case anyone else is interested in the 50HZ/100Hz switching, I've found out that the top range Sony Wega Trinitron sets do this.

Widescreen is ok, but you only get Widescreen 16:9 content on digital sources, eg, DVD, Freeview, Sky digital, Digital Cable. Even then most of the older "made for tv" content like Only fools and horses are still in 4:3 "square" format.

If you dont have access to digital content, you are stuck with 4:3 "square" via analogue for a while longer.

If you do get Widescreen signals (digital), then a Widescreen tv is great. But if you dont, then you have to choose between having a "square" picture with black bars to the left and right, or stretching the square picture to fill the screen. It could be said, that without widescreen sources, there's no point in having a widescreen tv - infact you would get a better result with a good quality 4:3 "square" tv.

Dont forget that any digital devices (eg, DVD, digibox, modern games machine) all have built in menu settings which need to be checked to make sure they are "outputting" a Widescreen signal - if you have a widescreen tv connected to it.

I've never had a widescreen set so for now my digital boxes are set to "4:3 centre cut-out". I don't miss what I can't see.
I'll carry on with them till they "drop off the perch" I was recently give a 10 year old (works perfectly) Panasonic by someone who upgraded, it will be a useable spare.
