Posh Pye CT474 (G11) TV Set

Hi R to B,

The picture is amazingly good ! I bet it's as good as the day the set was made. Mind you as I hinted at before this set is definitely a "low mileage" in fact I think it's only just "run in"

As for the potential soldering issues with these sets I think what I intend to do (once the IC socket arrives) is to systematically take out each panel and thoroughly inspect and re-solder as necessary as I have already done with the RGB panel.

I'm looking forward to using the Pye with all the 70s & 80s sitcom DVD's we have, they look so much better viewed on a CRT set rather than the modern flat panel we have in the room.

Marc.

Anyone remember the Prestel version of the G11? Malc.

Hi Malc,
I can definitely remember seeing the Prestel TX10, don't think I saw a Prestel G11, or at least I cannot remember seeing one.

Hi Marc
That's a real nice set you've got there .
We sold them new when I started in the trade , our family set was a 26" Philips version which when we we took delivery of it I soldered all the panels and it after that it ran fault free for 10 years.
The first fault being the smoothing block which only cracked once .it was switched straight off and a new block was fitted . It was still working a couple of years after that when we got our first teletext set.
Regards.
Gary.

Hi all,

Thanks to the kind donation from Malc a couple of nice NOS chip sockets arrived this morning so on with replacement.
After desoldering and unclipping the heatsink for the TDA2600 chip and then removing the chip I desoldered the old chip socket and found that 3 of the connections fell away from the plastic and one of them looked rather charred probably causing the original frame collapse. My guess would be that the socket was certainly on it's way out.
A new socket was soldered back in, the chip replaced with a fresh application of heatsink compound and the heatsink replaced.

I've also gone over the PCBs in the set and was actually surprised how good the original soldering was, beyond one dry joint and the missing solder on the RGB panel I found nothing else amiss with the boards but still gave them a re-flow to be on the safe side.

Marc.

: Note the 3 socket pins left on the PCB from the chip socket, they are not held by solder yet fell out of the socket.

: Old V new, of the 3 pins that fell out of the left hand socket one is chard.

: New socket and chip reinstalled with a light smear of heatsink compound.

: Job done and RGB panel ready to go back into the set.

That looks great, Marc. Now, isn't it about time you binned your flat panel and joined the CRT revolution...? :qq1

Don't think I haven't thought of that already young Catho....
Now how do I get around the 1001 things plugged into the flat panel ? oh and Mrs G too :qq1
