Hi Folks,

I'm looking at a 9242 for a Buddy, and he's got a least 2 of the Caps bulging. Do you know of any repair shop in the Metro Vancouver area who fixes these receivers?

Thanks for the assist.

Hi. Has anyone had to change the caps in the tuner section of the 9400
(won't lock onto SAT signals)?

Does somebody have a pic of the 9400 mainboard?

I'm thinking the tuner area would be similar to the 6400.

Some additional locations to monitor:

6131
same locations as 6141 as mainboards are similar

6400
C12 100uf 25V on PSU PCB

9242
C363 1200uf 6.3V (low profile)
C394 1200uf 6.3V (low profile)
C5, C6, C17, C21, or C58 2700uf 16V (rarely, sometimes 1 or two of those) on PSU PCB
C31 1000uf 200V (very rare) on PSU PCB

Of course, if you see any caps that are Teapo brand
in the tuner section or a power supplying section, they
should be changed even if they look good. Also, keep
an eye on Jamicon brand. Bell used better quality brands
later, but even those can go (and it's obvious when it occurs).

The 100uf ones are a pain to change as they are double-sided soldered on mainboard.
I would leave them unless you can't lock onto SAT signals mentioned above, after
changing the other recommended ones first.

Another suggestion from other online techs is to use
a min. 16V rated replacement cap, ones of lower voltage have
less reliable output. And also do not last as long. However,
I have continued using low ESR (mentioned on post #20)
long life Panasonic 820uf 6.3V ones successfully.

It also seems that people that have used a power inserter & SW44, or SW21 combiner/switch, etc. (vs straight from the LNBs to receiver SAT inputs) since the start - the tuner section caps last longer. Along with a quality surge protector. Just fixed a 9241 that was over 10yrs old (but left the 100uf ones alone) and it's working fine.

Regards,

I think i may have found another bad cap in the 6131. C494 looks to have busted. The receiver will not turn on. It's 33uf 35V.

EDIT: It was brought to my attention that there was a smirnoff ice spilled on the receiver which probably caused these caps to bust so disregard lol. The caps were replaced but the receiver only half powers up now. The green light comes on dim.

So about a year later my 9241 had enough of my procrastinating...

It finally pooped out after our last power outage (was quite a show, Raven arced out 2 40kv phases for at least 30 seconds lol). After that, it would boot with either no video or video would show and in either case would just keep rebooting after a minute or so

Changed out almost all the known issue caps, a lot of them were bulged a bit on the ends but none had totally failed. I must have had one too many drinkys when I ordered caps ~8 months ago as I failed to order enough to do the 2 under the shields. So all got done but those 2.

Now I’m back up and running. Pvr is still not working, same as before. But at least we’ve got tv again. I’d venture a guess that the 2 caps under the shields have no influence on the pvr operation, likely something else

The hard drive itself is likely failing
