If you have a digital tester or analog try to check the voltage reading from the power supply if high or low or no supply.Check first following voltage location and section. * Check the AC voltage from ac cord to fuse and before the bridge type diode. * Check the DC voltage after the bridge type diode.if normal voltage. * Then check the voltage into the filter capacitor to regulator ic.the power ic.If theres a input voltage in the power ic,check the output voltage going to harizontal output.If no output the problem is you power output.You need to replace it.

Hi, I have a sony STR-DE675.; the audio cuts out between stereo and mono, as if something inside is heating up.I have cleaned all connections and carefully vacumed out any dust from inside the unit.The...


STR is a very sensitive ic module of the audio system and it always has a tendancy to heat up quickly and has some basic precautions to be maintained for operating this. correct speakers should have been connected so on..



if you are technically very confident open up your system try to locate the str ic unit check whether the contacts of the heat sync (aluminium metal chunk screwed with the ic to absorb the heat) has been correctly fixed. (pls note- manufacturers will always have appropriately heat synced it try to use it in a cooler place)

Audio protect keeps turning off my receiver (sony STR-DE597)


That is the common symptom of the defected STK-IC in power amp.section that busted already or just a loose connection.First try to resolder the pins of STK-IC and also all component parts joint in power amplifier section if its works! if not that is the time you replace it, so it works normal again.

Hope it may helps you...

Sony tv no picture only horizontal line


The probable defective part is the vertical IC. If changing that does not resolve the problem, check the capacitors in the same circuit. Also, check for the proper voltages at the vertical IC. If the IC is not being fed its power, it won't work either. I don't have a listing for your specific model. If you can post the vertical IC part number (LA7837 for example), I can list the voltages per pin.
