Audioguru is right about the PIV of a rectifier should be higher than the peak inverese voltage of the AC wave it is connected to. Please note that in a half wave rectifier circuit WITH A CAPACITOR to act as an energy storage device to smooth out peaks and valleys in the rectified voltage, the...
Well, old faithful finally conked out after 17 years of use. Dead vertical output. Can anyone point me to a schematic or service manual for this model? I know I can fix it even without the schematic, but more advance info would certainly help. Thanks in advance.
Thanks for the input guys, but I'm afraid the problem intermittently clears up for a few seconds (picture becomes perfectly normal) and then returns to the non-normal state. So it's an electronics problem, not a magnetized picture tube problem.
I'm just an electronics hobbyist,not a service tech. Can anyone tell me where I should start troubleshooting my eMachines CRT monitor? It shows a slight out of focus at the bottom right of the screen and there's also a slight "ghosting" with an orange color of a part of any object displayed...
Hi all. i'm troubleshooting my CRT monitor and need a schematic to go. I think it's the jungle IC (STV7778) but I gotta check out other components before I replace that 42-pin chip. Symptoms: Loss of vertical sweep (horizontal line across screen) that quickly returns to normal. Later this...
