Re: Sylvania LC420SS8 Power Supply Troubleshooting

Just read enough of the service manual to realize all my debugging of the power board while disconnected from the digital board is totally invalid. Will reconnect those tomorrow and debug from scratch

Hi Badcappers!

The TV shows no signs of life, but no capacitors appear bad from visual inspection.

Some voltages during standby:

Hi fellow badcappers.

Software developer in Ottawa looking to fix a TV for someone on twitter. I've fixed digital circuits before but I've traced this one into the high-voltage analog section and have no clue what's going on
