Sony TV blows fuses

hondgm: Wow.... a little optomistic with your following statement.... "I'm no TV repair expert, but it seems this one should be relatively easy, if I had a schematic."

Take the hot OUT of circuit and test it to make certain it is not shorted.... your statement "it didn't seem to be shorted" does not inspire a lot of confiedence. Be aware that the HOT can fail and not neccessarily show a direct short on your meter... it can have fatal CE leakage that won't show up as a short. ..... and check the bridge, you should know for certain that it is good and not that it "appears to be fine." Check the B+ voltage regulator and/or replace it and also for shorted/leaky filter caps in the the raw B+ and the regulation circuitry. Also check for shorted caps and faulty diodes in the flyback derived B+ circuitry.... all of this is relatively easy to find without a schematic. Daniel Sofie

The fuse rarely blows on those Sony T.V.'s, even when they blow up. Unhook the degaussing coil, just in case it is drawing too much current at turn on, but first check the two 2SC4834 switching regulators.Q601/Q602 (P/N# 872901951), R607 0.1 ohm fusible, (P/N#

Are you sure you're looking at the correct set? On this one, I don't see a Q602, R607, or any VDRs, and Q601 is a little TO-92 package.

start by checking the degauss circuit. unplug the coil and see if that helps.
