Re: TV Sony NSX-40GT1 (Power Supply)
Thanks for the link (Telford Television) ReeceyBurger123; there were nothing that power supply. Also thanks to budm by links to shopjimmy and ebay, TV has not damaged the resistance "R6536" as mentioned in ebay to buy the repair kit. Thank You for Your help. If anyone has the schematic of the power supply they are grateful.Comment

Re: TV Sony NSX-40GT1 (Power Supply)
I have potentially the same problem with Sony NSX-40GT1, 4.5 yrs. old looking for repair manual ( service manual available not needed to troubleshoot) which seems not to be available on any sites. Issue with tv was it went black & no sound, two blinking red lites ( 5 sec pause) where normally green. Checked power supply output @ 13 pin connector, only standby pin had correct 3v. No output voltage on other pins ( some are grounds), caps look good without testing, could transistors be failed or possible a voltage regulator? I can not find schematics for this tv. I do not think the tcon board is bad, main board not sure if ok either.Comment

Sony GE4A Schematic is very close to this power supply.Comment

Re: TV Sony NSX-40GT1 (Power Supply)
dead and 2 blinks.....REPLACED SHORTED FETS Q6101 & Q6102 (2SK4084) WITH (2SK3563) AND REPL OPEN RESISTER R6536 WITH .47 1/2 WATT SONY PN 1-220-926-21.. SAVED NEEDING TO REPLACE THE SMPSComment

Re: TV Sony NSX-40GT1 (Power Supply)
Thank you! I had the same blink pattern and this worked great for me. I ended up using TK5A50D MOSFETs as they were the recommended replacement for 2SK3563. I could not source the Panasonic part and used a 1/2 watt fusible resistor (Vishay NFR25H0004707JA500)
Thanks again!Comment

Vizio e601i-A3 - Has Sound and Display, But No Backlight - Bad Power Supply Board or Bad LED Bulbs ?I was given this TV from my great uncle. He said it just wouldn't turn on one day out of nowhere, replaced the TV, and gave it to me to possibly fix and use for myself.
Upon bringing it home and plugging it up, it showed a standby light.
I powered it on and without a flashlight, the display showed the "V" but the lighting is very dim, but visible.
The screen seems to blackout and stay black, but with a flashlight I can see the display.
With my Playstation 4 connected via HDMI, and running a game I can hear sound.
Assuming... -
I have wanting to do this project for quite sometime now and I finally found a switching power supply that will work on this desoldering gun station ZD-915 that the original switching power supply took a shit and just was not worth trying to fix it because this switching power is not quite big enough to handle the heater element and the vacuum pump
One note when I tested the switching power supply and the voltage control board I noticed that this desoldering gun heat up much faster than the original switching power supply which I was really surprised by to the point that I might buy... -
I have been working on this concept for quite some time now with limited success but recently I found a switching power supply that is setup for the voltage that this soldering station needs to operate at however it also needs part of the secondary circuit from the original switching power because you need several voltage rails
I once tried to get a ZD-915 desoldering station to work on a 18 volt battery power supply but unfortunately things did not go well but I did find a work around but I might try this idea again but going at a little differently more about this another time... -
The sub developed a constant popping every couple seconds from woofer and power LED flickering with nothing but wall AC connected. Connecting an audio cable didn't change anything. It doesn't play but a second or two of audio in between the pops.
Opened it up and discovered the power supply is making a faint clicking or ticking sound.
I measured the amp's output to the woofer and it pulses up to 50mv DC to be driver. The pulses coincide with the power supply ticking/clicking.
I measured the power supply output going to the amp board and it too has this pulsing. Voltage cycles... -
I have a 15 - inch Retina MacBook Pro from the mid - 2014 model. Here is the link: https://www.badcaps.net/forum/showth...light=820-3662 . The battery broke some time ago. After I removed the battery and plugged in the original power adapter, the MBP could boot up normally. However, when I checked with IntelPowerGadget, I found that the CPU speed was limited to 0.8 GHz, and it ran very slowly. Later, I found a solution on GitHub. There is an open - source project called cputune that can set the CPU running speed. So I can now run the MBP at full speed. But another problem...
