I have a Phillips 3055 scope was using a voltage divider circuit for looking at a transmitters audio envelope. Well the one i was testing over powered the scope and smoked the resistor on the a channel it did not take it out completely but the scale is foo now the main problem is the screen it didn't have the shadows around it before now it does i have to lower the intensity to get rid of it but would like to repair it. Any clues on what may have went? 2 photos of it one with intensity turned down and one were it normally was set at. thanks for any help.

I have an LG Plasma TV 60PM6700 for the past ~12 years.
In the last ~3-4 months I have been having some issues.- Problem: It started with random picture disappearing (sound still worked).
Frequency: Happened about once a week.
Solution: Had to turn off TV wait a few seconds before turning it on again. - Problem: Then it got worse and the TV started to shut down and when turning on the no picture just sound.

i have a problem with thinkpad X1 carbon gen 2 "LMQ-1MB 12298-2 48.4LY26.021"
The laptop was turned off because the MOSFET was not transmitting voltage. After checking it turned out that the gate pin on the MOSFET was the problem, because it was producing an inappropriate voltage. and it was discovered that the problem was with the Think engine, so I decided to reprint each pin, and finally the mosfet could work properly. However, there is another problem, even though the voltage has been supplied to the laptop, it still won't turn on, there isn't even an LED indicator. After double... -

Hello,
I have an old BK Precision model 1472C that is working but not the intensity ?
At connector P309:
Pin 1 +5V
Pin 2 when I turn VR2, goes from +.648 to +5.07V
Pin 3 GND
R356
Pin 1 when I turn VR2, goes from +.648 to +5.07V
Pin 2 no matter how I turn VR2, voltage stays at +5.7V
All the resistors around are good, except maybe R355 that reads 37K instead of 48K.
I also would like to know what TC302 (capacitor trimmer) is used for, because when I turn it, nothing happened ???

Problem description:
Hi. I have a problem that has been going on for some time (2-3 years). It's hard to explain what it really is. Sometimes, my computer stops playing music, stops videos (starts buffering on youtube), there is no sound in games and when I minimize the game window and return to the game there is a black screen with window borders...
