A small (6") portable TV with TFT display is presumed to use the usual
cold-cathode backlight. Does frequency of starting affect the life of
the tube - i.e. is it better to leave the set running for extended
periods, or keep switching it on and aff as required?
I have heard it suggested that these small tubes have a limited
lifespan and that replacements can be difficult or even impossible to
find or fit. Comments please?
TIA
