I have a crown i-t8000 amp and it wont power up. When I attempt to power up I hear the fan for 3 seconds and it stops, nothing on display but the power led stays on. Does anyone have any suggestions or the service manual to this model?

Re: Crown Amp
I opened the unit. Checked the voltage coming in. I get 120 volts. I next checked the voltage at the on/off switch with it turned off I get 120volts. I turn on the on/ff switch and I get no voltage. Does this mean the switch is bad? -
Re: Crown Amp
I do not expect the power LED to stay on if the power switch is bad.
How many terminals are on the power switch, 4? or 2?Never stop learning

Re: Crown Amp
It would be very helpful to get some pics for us of the whole unit, and each circuit board. Might be a bad power supply, or bad amplifier parts.Muh-soggy-kneeComment

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.

Hi Everyone. First official post so fingers crossed I conform and also manage to get photos to work.
So I am requesting some help from anyone who happens to have one of these motherboards to hand and perhaps a multimeter.
My board has a single row of header pins for all the front panel stuff (have seen others where they are grouped together differently so thats no help) and the two pins for the power on switch had been previously repaired and I am trying to make a better repair. There looks to be pad and trace damage and im happy to relocate the header pin/pins to...06-24-2024, 01:24 PM -
Hello,
I've been working on a NEC TurboExpress and I accidentally got the plastic inside the power ON/OFF switch too hot while doing other repairs and melted it. At first, it would still power on when sliding the switch, but you had to really press inward while sliding to get it to work.
I removed the switch component and tried to gently melt the plastic back so it would work more reliably and all I managed to do was make it worse.
I need to find a replacement On/OFF switch for this, but having some trouble figuring out which kind of switch I need.... -
Hi all,
TL;DR - this laptop is driving me nuts with the oddball power-related behaviors. Appreciate any insight you can provide!
I'm experiencing a power issue on an Asus Probook P5440UF-XB74. Although I've worked with electronics and computers for decades, this is my first attempt at getting into motherboard-level component troubleshooting. Any help the community can provide is greatly appreciated!
