Panasonic TX32DK1

Hi everyone in the UK. Is there an Engineer out there who happens to have a TX32DK1 on his bench at the moment????? You won't believe this one!! In the good old days I could have solved this one by putting a message on the good old engineers bully board but since the demise of the Viewdata system Pana don't seem to have got going again in this way. Perhaps they don't want us to talk to each other as it might be dangerous? We had one of these come in with a low emission CRT. After much wrangling with Customer Services we managed to get them to honour the CRT provided the Customer pays us for the labour. Fine, no problem. Ordered replacement CRT. Substitute came in and when checked with Pana Tech it is a direct substitute. Changed CRT after a couple of black coffees and pinching my hands under the CRT rim (ouch!) Reconnect all leads to chassis. Went to connect scan coil leads - not supplied with new CRT. Needed to change them across from old CRT. Made note of connections to scan coil. Unsoldered the old scan coilleads. Knocked off for the day with the idea of connecting the scan coil leads to the new CRT the following morning. Came in the following morning and whoops, where's my bit of paper?? No problem, looked it up on the CD Rom - oh dear - scanned in version and the scan coil connections were not in the cct diagram or in fact anywhere in the svc manual. Contacted Pana Tech. Absolutely no clues. Suggested they wandered into their Workshop and copied down the connections from a set in their Workshop. Don't see old CRT's anymore - too busy climbing all over big LCD and Plasmas! There's got to be someone out there who's got one in the Workshop at the moment. If so, would be very grateful for colours left to right (looking at the back of the CRT ). Scan coil has 5 pins, Pins 1,2,3 and 5 are the connections with pin 4 being used for a couple of resistors - that bit I can remember!

Many thanks

Paul

You should be able to determine which two pins connect to the same winding. All that's left is to determine which pair are H and which are V, and their polarity. A resistance comparison between old and new scan coils may be enough to identify H&V, else an inductance test may be more conclusive. Incorrect polarity will cause no harm, but will be evident from the picture.

Hi everyone,

I have recently had brightness problems with my TX32DK1, which culminated in one of the capacitors blowing on the small CRT circuit board (the one that plugs directly onto the CRT). I would like to replace the capacitor, but unfortunately, the marking on the canister has been destroyed in the heat. The Capacitor number on the circuit board is C361.

Does anyone have any idea what value it is, both its capacitance and voltage rating. Better still, does anyone have a diagram of that circuit board.

Many thanks

Keith

Thanks Art, Seems good to me.

Does anyone else have information?
