Weak or no signal problem

Hello everyone, hope you can help.
I got a new HDR-1100S May 2016, installed here in France and all fine until a few weeks ago.
We had an electrical storm and a lightning hit very close - a couple of circuits in the house tripped. A short while after I realized that the box was not giving any programs. After research online everything pointed to a goosed LNB (quad)so a new one was sourced and fitted.
The lnb has two feeds to the Humax and a single feed to a sky box in our rental cottage. The single feed to the sky box was ok, but it appeared that one of the feeds to the Humax was not good - Tuner 2 was only showing about 30% strength and 60% quality. I swapped the feeds around at the LNB but nothing changed. So swapped them at the back of the box and again nothing changed.
All connections were checked and rechecked..all good.
Then we get channel weak or no signal messages while changing chanels..not all the time. Some planned recordings not happening.
Checking yesterday this is the situation:
Tuner 1 always shows excellent strength and quality, Tuner 2 bad strength, good or poor quality.
If I hit record on 101 (BBC1) and then tune to other channels 102 is missing, 103,4,5 ok, 106 missing, 108 onwards ok. When tuned to 102 and recording 101 and signal checked it says no signal on tuner 2. When not recording on 101, the signal for tuner 2 is bad strength and good quality.

I've done a factory reset (did not loose recordings)...

Anybody got any clues?

Thanks,

Steve

It is sounding like tuner 2 is failing to switch bands.
Can you clarify "missing" do you mean no signal or absent from EPG?
What regions does your unit set receive?

Thanks Repassac.
By missing I mean that no signal message is given - the channels are shown on the EPG.
The box is set to receive NE England.

I am in France and have forgot what that translates into BBC and ITV regions.

Can you make two lists of the channels Frequencies and the letter after them (Polarisation) one for OK and one NOK please.

See https://www.lyngsat.com/Astra-2E-2F-2G.html

p.s. If you just swap the lnb connections at the rear of the unit does the problem stay on tuner 2?

Repassac - we are in France as well - Charente Maritime.

I've no idea how to find out the channel frequencies or polarisation....

I did swap the feeds into the box, but the problem is always on tuner 2.

While recording 101 BBC the following are ok:
103, 104, 105, 108, 109, 111, 112, 114, 119, 120, 125, 128-133, 140, 141, 151, 162, 200, 203, 207, 208, 211, 213, ....

Not Ok:
102, 110, 113, 115-118, 121-127, 142-161, 164, 165, 167, 169, 201, ....

134-139 were not ok but in addition the no signal message did not appear..

I did not go through all the channels.....

Hope that is enough to identify the problem.

Thanks,

Steve

Steve - the link I gave you above was a list of channels/frequency.

While you appear to especially have problems with vertical polarised channels there is an exception to this.
The freesat channel list implies that on 102, which I would expect to be BBC Two England, some users receive the HD version. can you confirm that you normally get BBC England (SD) on 102.

Repassac.. thanks for your help. I'm sorry - I read your post on my email, did not see the link, then replied on the forum...apologies.
However I've since followed the link and am totally confused by all the info..can't seem to make head nor tail of it...to further frustrate me (very easy) our Satellite Broadband service at the moment (end of the month) is being 'squeezed' and it's difficult to use for any length of time.
I can tell you though that channel 102 is BBC 2 HD, 108 is BBC 2 SD..

Thanks again,

Steve

Repassac I think 110 (the only horizontal channel) may be a red herring being BBC 4 which is a evening only channel and may simply been off air. Suspect a check of Cbeebies on 608 (which is shared with BBC 4) would have worked. Perhaps the OP could check this.

Can I suggest the OP uses the BBC-SD regions for the test recordings in the 900s as then the transponder in use will be known.

One from a vertical and one horizontal one and see if the missing list are all vertical.

950 BBC 1 London 10773 H
951 BBC 1 CI 10773 H
952 BBC 1 E Mids 10788 V
953 BBC 1 East (E) 10788 V
954 BBC 1 East (W) 10773 H
955 BBC 1 N West 10802 H
956 BBC 1 NE & C 10802 H
957 BBC 1 NI 10817 V
958 BBC 1 Oxford 10817 V
959 BBC 1 S East 10802 H
960 BBC 1 Scotland 10802 H
961 BBC 1 South 10817 V
962 BBC 1 S West 10817 V
963 BBC 1 W Mids 10788 V
964 BBC 1 Wales 10788 V
965 BBC 1 West 10773 H
966 BBC 1 Yorks 10802 H
967 BBC 1 EYrks&L 10788 V

Suggested list of horizontal channels to check which presumably will work

Sample Channel Number Channel Name Frequency Polarisation
104 or 608 Channel 4/Cbeebies 10714 H
108 BBC Two Eng 10773 H
955 BBC One N West 10802 H
112 ITV +1 West 10832 H
112 ITV +1 10891 H
105 Channel 5 HD 10964 H
200 BBC NEWS HD 11023 H
119 ITV HD (Tyne Tees) 11053 H
162 BLAZE 11082 H
140 BET 11141 H
304 Movies4Men 11170 H
250 Front Runner 2 11223 H
505 Vintage TV 11263 H
251 BIKE 11306 H
139 horror ch+1 11389 H
211 CGTN 11464 H
801 QVC Beauty 11493 H
507 CAPITAL TV 11552 H
691 DAYSTAR TV HD 11612 H
207 CNN 11670 H
146 Challenge 11836 H
753 RTE RnaG 11953 H
508 Kiss 12304 H

list of verticals that presumably will not work

121 Channel 4 + 1 10729 V
103 ITV 10758 V
952 BBC One E Mid 10788 V
212 BBC NEWS 10817 V
102 BBC Two HD 10847 V
115 ITV3 10906 V
111 ITV Central West HD 11097 V
127 4seven 11126 V
209 NHK WORLD HD 11225 V
692 Revelation 11265 V
142 True Ent 11306 V
134 CBS Drama 11343 V
870 BABESTATION 11343 V
695 Sonlife TV 11390 V
143 True Crime 11426 V
210 CNBC 11479 V
306 TalkingPics TV 11538 V
806 JML Direct 11567 V
161 SHOWCASE 11597 V
790 TWR 11685 V
511 VIVA 11895 V
158 Drama 12129 V
144 PICK 12207 V

Guessing tuner 2 will only output approx 18 V so unable to switch to approx 13V to get the vertical channels.
