If the quality on a channel varies, then weather "effects" could be the most likely culprit. But there ought to be times when it is still 100% quality unless you are in a particularly bad location (you shouldn't be). If you aren't in the habit of checking such things on a routine basis, then it could be difficult to know whether things like Tropospheric Ducting is responsible or you have some other form of more stable interference that's been present for a while. Do check the HDMI lead situation and other equipment if you have any.
Also check that your aerial is intact (particularly when it comes to the reflector) and still pointing in the correct direction - bearing 223 degrees, virtually SW for your area.
One thing I've not mentioned to you is that Rowridge transmits both horizontal and vertical polarisation for the main 1-6 multiplexes, where as COM7 and the Local mux are horizontal only. The power for Vertical polarisation is also the same for the main muxes.
You are predicted to get "variable" reception for the COM muxes with horizontal polarisation, but good with vertical - you'd lose COM7 and the Local mux with vertical polarisation though. You might like to read a couple of our replies to viewer Stuart (from Bognor Regis) on p195, so the problem with reduced reliability for COMs4-6 could be interference from Crystal Palace, but it's slightly strange that you are only getting an issue on C28.
You are predicted to get good reception of the Local Mux though, and I'm struggling (off the top of my head) to think of which transmitter might be the source of your current issue, as most relay transmitters that might use C37 use vertical polarisation (and low power) - another reason to check your aerial is intact and pointing correctly.
Interference on specific channels could also come from a near neighbour. Might be worth asking what their reception is like for C28 & C37 if their aerial is horizontal. Interference from further afield such as faulty street lighting generally affects a broader range of frequencies, but Radio Frequency problems can sometimes be a bit of a black art!

Just to add to the above, C37 interference might come from the Oxford transmitter which uses C37 for COM5. One coverage map suggest that some signals might get to some spots around the Petersfield area under normal conditions! Propagation can be quite frequency dependant in some circumstances.

Chris, Thanks for your replies a lot of information there to digest, strange no problems with picture breakup again last night, checked my aerial connections and as for aerial direction it has not moved, its looking like it is an atmospheric/weather type problem which has corrected itself at the moment, will keep an eye on it, thanks for hourbgimecand input....cheers

No problem, post back if you want any more information or advice.
FYI, I'm seeing two conflicting reports about "Tropo" over the coming days. One saying there'll be some building this evening affecting most of the south coast and eventually affecting the whole of southern England by tomorrow. Then mid-week into Friday, some potentially strong and variable trop through to Friday affecting a large chunk of GB. The other, not a lot, may be some affecting the NE on Friday! No current warnings from the BBC either (nor Freeview, but then they are pretty useless anyway!).

Chris, re your comments about reports of "Tropo" today, it looks more like that is the problem at my address as Ch 28 and ch 37 are really bad today , both are bouncing quality between 0% to 18% , going from bad pixilation to no signal, so guess I'm stuck with it at certain times of the year...

Oh bad luck. If it gets too frustrating, you could consider Freesat. A lot of modern TVs have an inbuilt satellite tuner, so all you'd need would be a Dish and LNB. See Channels List & On-Demand Players | Freesat for the channels currently on Freesat.

If we lose BBC4 HD and BBC News HD etc at some stage, is there a published date for when they should reappear on Rowridge?

There is absolutely no information available about what might/could happen to any of the channels on COM7 at whatever point it closes.
.gov have just announced that the other multiplex licences can be extended to 2034
Future of channels such as ITV2 and Dave secured as Freeview licences renewed for another decade - GOV.UK
But apparently the BBC have yet to confirm if they would apply for renewal of the licence for it's HD multiplex (BBCB HD/PSB3) until it became clearer what the role of the multiplex would be !!
That strikes me that people might want to write to the BBC and tell them - IMHO it should be more HD channels on Freeview, not even contemplating less!

Poor signal strength 46% and 0% quality on Ch 25 from rowridge transmitter. Previous Panasonic tv used to play transmission but new LG suffers with dropout. Is ch25 channel owner given lower output?
