Hello, I came here after finding some similar questions asked on other monitors and hope someone here can help me get an ancient Viewsonic VP230mp (23" 4:3 LCD) back to working condition.
First a little background, I have a background in computer and electrical engineering, and I'm smart enough to know I know nothing about LCD displays and how they work. For this topic I'm as green as they come.
When the display is turned on the viewsonic logo displays in the uppper left for 2 seconds then the screen goes black, the power LED is green (on) and when a computer is connected... -
Hi.
I have some problem with old CRT TV Samsung model: CW-29Z338T, 29" size TV.
The problem is that letters and other text are not clear, text or letters are shadowed on the right side.
I found 2 capacitors on CRT Picture Tube Board.
47uF/400V was leaking very bad, the second cap 10uF/250V was bad ESR reading so i replace this cap also.
Replacement these 2 capacitors did not help nothing.

Hello everyone
I have been working on this laptop mentioned in the title, it initially had a blown PQ4410 mosfet. After I replaced it and repaired the damaged PCB the thing started working again, but there is still another problem. The laptop won't recognize genuine battery and charger. I have 3.3v KBC PIN36 PS_ID and this is pretty much where my knowledge ends.
Where should I go next? Replace the KBC or measure something else?...
