How can I stop my rear projection TV from flickering?
I have an old(ish) Sony rear projection TV. I think it’s a 32″ model, number KPW41MN11. Recently it’s started ‘flickering’ when I turn it on, and tonight it started actually ‘flashing’, by which I mean the picture sort of ‘pulses’ on and off at a rate of about one ‘flash’ per second.
I’ve opened her up and it seems like the red and green ‘lamps’ (I don’t know if that’s what they are, forgive my ignorance!) are flashing this way but the blue seems to be fine. It’s quite an old TV and was given to me for free, but I’d still like to try and repair it if at all possible. It’s probably not worth the cost of new lamps (I hear they can be quite expensive) but if the lamps are just ‘flashing’ rather than not functioning at all then I figured maybe it’s just a dodgy capacitor or something on one of the boards?
If anyone has any insight please let me know. As I say, it’s an old(ish) unit (as in maybe 10 years?) but I’d like to know if it’s likely to cost more than its’ worth to fix.
