Repair Notes
- Unit's raster was shrunken on both axes and out of focus. Since both the vert and horizontal were shrunken my first guess was low B+, which it indeed was 70v instead of 130v. I removed the h.o.t. and put a dummy load (light bulb) on the B+, and the B+ was still low suggesting a power supply issue. I put the h.o.t. back in. Rectification tested correct so the issue was with the B+ regulation. The one electrolytic in that circuit had relatively high ESR around 30 ohms, though replacing did not fix the issue. Checking all the rest of the components in the B+ regulator circuit revealed that resistor R435 130K had gone open. Replaced with 100k and 33k in series.
Notes
If the channel number stays on-screen and does not go away, there is a toggle for it in the display settings.
Some other sets with this chassis used a separate audio/video jack board with opto-isolators to add a composite input.
This CRT is confirmed to be a hot chassis.
Hot Chassis means that "ground" on the chassis is tied to one side of the AC input from the wall, and touching it with your hand will complete a live circuit through your body to earth ground if the CRT is plugged into an AC outlet. The proper way to avoid this danger is to use an isolation transformer to isolate the CRT from earth ground and prevent electrocuting yourself.
