As noted at the top of the page, the transmitter is currently listed for Planned Engineering, other that that is could be current weather conditions.
There's some significant "Tropospheric Ducting" affecting differing parts of the UK very randomly.
Do NOT retune.
These conditions cause signals from distant transmitters in Europe or the UK to travel further and result in interference to your wanted signals. This doesn't always affect all multiplexes at the same time and may not affect all viewers. It can last seconds, minutes or for longer. There is little you can do except wait until conditions improve - or try watching online etc.
If you did retune when you had badly pixellated pictures or no signal (whatever the cause and never advised if you were correctly tuned) this usually just clears your correct tuning. You'll then have to retune again which you may have to try several times as you won't know when signals will be normal.

Hi, I have had little or no tv signal for 7 days now.. at best there's just constant pixilation but mostly every 30 seconds black no signal screen. Initially freeview page stated engineering works began on the Chrystal palace transmitter commenced May 8th.. now it has changed to commencing May 15th but there is no information regarding as to when it is expected to be rectified. Does anyone know?
Many Thanks
