Need help diagnosing DVD/VCR Combo player
Friend of mine gave me a Sony SLV-D300P DVD/VCR Combo unit to look at. It does not power on from the front panel switch or light up to show it has any signs of life while plugged into the wall. I at least checked to see if the switch has continuity and if the input voltage to the unit can read after the main fuse. Other than that- ???? I tried to look at some repair technician forums, but can't get access. Anatek isn't much help with this newer model. Just wanted to know if this model has specific inherent problems that could be simply fixed much like the motherboards I've been repairing. Thanks guys

I'd check output voltages of the power supply first. -

I am trying to repair an LG split AC indoor unit, which does not start and gives a CH05 error code.
This indicates an error in the communication between the outdoor and the indoor unit.
The outdoor unit is fine, so the problem is the indoor PCB.
The indoor unit is an LG PC09SQ NSJ (3SNM09JA2FA), and the PCB has the following type number: EAX35907219-1.2 (see photo1)
I changed optocouplers ICO1X & ICO2X and the NPN transistor S9013 which drives optocoupler ICO2X (see photo2), but this did not remedy the fault.
Does anybody have the schematics of this board,...02-01-2025, 12:55 PM -
Hello!
My mother has a Victrola Navigator player that stopped functioning after a storm. I checked out what I could - all player functions appear to work, but there is no audio output in either the speakers or the headphone jack. I suspect (with my limited knowledge) that the amplifier part of the device is toast. Photo of the suspected board is attached. There's separate boards for front display, record player, etc. This board has a section for power regulation and a section for amp. There's a UTC7266 7+7W dual bridge amplifier IC and a CSC2314F sound processor IC on the board. Visually,... -
Hi guys,
Trying to salvage a Bose Companion 5 computer speaker system that powers off shortly after powering on. It's got a primary USB input (built in DAC) and an aux 3.5mm input. The USB appears to be the primarily source that tells the unit to power on (control pod LED goes green) as the unit has no power switch.
When I first connect power to the unit, plug in the USB, it will play audio nicely for a minute before it drops out and the unit appears to go into standby (control pod LED goes red). It stays in standby and I cannot seem to power it back on without physically...02-03-2022, 11:14 AM -

Hi all, I managed to narrow down which PCB was causing my Haier AC to throw out an E7 error code (E7 indicates that the indoor unit and outdoor unit cannot communicate). I found that the outdoor unit power board which gives 5v and 15v to the outdoor unit module board fails to fully power up.. The power Led starts to fade in incredibly slowly and the 5v and 15v power buses jump around like crazy and never reach their required voltage. I unplugged the module board from the power board and the power board powered up fine! It had a steady 5v and 15v out and the power LED came on instantly and Bright....
