Mitsubishi CT-37C1STX 37 inch CRT TV info needed - UK Vintage Radio Repair and Restoration Discussion Forum

Chris Wilson · 3rd Jan 2016, 6:36 pm

I have acquired a huge Mitsubishi CT-37C1STX 37 inch CRT TV with side speaker cabinets. I got it about 5 years ago as a supposed good set, and it sat in dry but dusty storage in the attic. I tried to power it up the other day after blowing it off, and zilch, dead as a dodo. I have lost the remote, but it does have a conventional looking on / off button. Has anyone come across one of these leviathans, or better, knows where I can find schematics or a service manual please? My pal who helped lift it in has refused to put his back out taking it out to the car for a trip to the tip, so I best try and get it working

Thanks and happy New Year to all on the forum.

I worked on these sets years ago. The common problem was the electrolytics in the psu. There are quite a few of them in the primary and secondary, replace the lot.

Is this the early type of 37 " ? . as there was another model about 2 years later
which looked much more television shaped slimmer grey plastic cabinet , with three detachable speakers .
usually caps and high value resistors in the start up circuit around 330k
