I replaced the backlights all good. Two months later set was dead, had a shorted D9100, replaced all good again.
Now months later set powers up,backlights light ok,no picture. 12volts missing from fuse on tcon. 12VA on power
supply is 19 volts. Changed D9100 again, same, 12 volts measures 19. Am I looking at a power supply or mainboard
issue. Set will power up with remote but not power off.... -
Picked up this Samsung above thinking it'd be backlights but it isn't. Now MAYBE I'll get lucky.
Found some shorted caps among the panel boards. Each cap along the line is shorted. On every board (3 panel driver boards)I disconnect each side right and left ribbons and they are no longer shorted caps and have about 1.5Mohm resistance (on left and right boards). The middle board has the main board disconnected and the caps are shorted. Last 4 pics show arrow to caps.
Now what exactly do I need to do in order to attempt to fix this issue?
do I have to take each one... -
Hi there,
i am at the present struggling with an iPhone 13.
Can someone tell me the values of the three caps marked in the picture close to Pin 1?

Hi, I'm unexperienced with troubleshooting and I'm not sure how to proceed with this laptop.
Motherboard is A5WAH LA-B991P I think, i5-5200U and nvidia 820m.
When I received the laptop, CMOS battery had 0V. I took it out and all the testing has been done without a CMOS battery and without the main battery plugged in, I haven't been able to see physical damage, burnt or missing components with a quick visual inspection, and no shorts were found.
Laptop charges the battery, powers on when ON button is pressed when powered from charger and when powered from the battery, but... -
Hello,
First, I am a complete noob with high voltage stuff. I'm learning, but I need help by someone looking over my shoulder.
I recently came into posession of a Heathkit IO-4205 5MHz Dual Trace Oscilloscope. The documentation is copyright 1978. I'm told it works.
I opened it up to check the caps before I applied power, and found the following black caps and wanted to know what they were. They are on the power supply board. I was able to read the name and model and came up with, "Nytronics 162J-1, 0.1uF, 20% tolerance, 2000VDC."
