Have a Samsung HP-T5054 plasma tv with power supply problem. Came back from vacation and set was dead. Main fuse and varistor were bad. Measured dodes in bridge and I thought they were open until I switched to 400K range on meter and they checked 250k each. I thought most diodes in power supply read about 600 ohms. Am imissing something?

Hi,
you can not test Diodes in Ohms Range, use the diode test on your meter.
Measure forward voltage to check bridge.

a cct-diagram would help
