This morning our FVP4000T (in daily use) gave a blank screen, EPG says something like ‘no information on all channels, trying to select a channel gave a massage to the effect you can’t do that whilst recording or streaming (no recording or streaming taking place). We can watch what has been recorded fine. Signal strength and quality gives 0% on all three tuners. Is there anything inside repairable? I can do PTH soldering though not Surface mount.
