I have a Sony STR-D1015 that has gone into Protector Mode. I have read a lot about bad solder joints and other problems with output transistors. I took all the speakers loose so I know it is internal. I have also read there were several people that had a problem with the STK350-130A going bad. Can anyone tell me how to tell if the STK350-130A is good or bad? Any other trouble shooting tips? I work on TVs as a hobby but haven't done any Audio stuff.

Re: Sony STR-D1015 Protector Error
You can down load the spec sheet and check to see if it has DC offset voltage at the output pin. Or check at the speaker relays terminals (the one that is connected to the out pins of the STK.Last edited by budm; 01-07-2014, 03:02 PM.Never stop learning

Hi everyone!
I have a Sony KD-65A1 TV with a fault – 4 red LED blinks. After disassembly and visual inspection, I found that the G76 power board and DKA board had been replaced. It is also possible that TCON was replaced, but I am not sure – there are a few marker marks that could be factory-made.
Based on assumptions, the previous service attempted to solve the issue by replacing potentially faulty components. I decided to investigate further, found a service manual, and figured out a way to power up the power supply unit autonomously and put the OLED panel and... -

Hi everyone. First post on Badcaps!
I am trying to fix a Sony 940E from 2017 that either starts normally (and works perfectly until turned off) or goes straight to the 6 blinks error code without showing anything on the screen. It is frustrating to know that it can still work perfectly but is barely usable because of the difficulty starting it up. I am willing to try to short the BL_ERR but I would like to avoid that if possible. Does anyone have a view on this? Thanks a lot.... -
one of our new (only 4 year old) 1KVA APC UPS stop working and through error P13 contact customer support.
the equipment is out of warranty , upon investigation, we found the inverter board has the fault on the output hybrid relay circuit.
The inverter output relay is parallel by SCR/Triac to enhance the relay performance or other means.
We replaced the SCR with new device,, but the device is not power on as expected.
Further research on the issue found that, the error P13 (event ID 107) is latched on the UPS nvram/MCU and need to clear/reset using a service procedure....09-26-2025, 09:00 AM -
Recently I was given for free a Sony RCD-W3 with the following symptoms, CD recorder drive reads CDs without any issues (haven't tested recording function yet because I don't intend to burn CDs on that machine) but the reader drive shows disc error after some seconds of it trying to read CD. Tried both CD-Rs and commercial audio CDs with same results.
First thing to do was to clean the lens but that didn't change anything. Googling the issue revealed that this is a common issue on several Sony CD recorder machines and the culprit is SMD electrolytic caps located on the PCB bellow...05-05-2024, 02:04 PM
