If you are able to hear audio but no video, your Ysus assembly might be defective. It could also be your power supply not providing all the voltages to the different assemblies on your TV.

Gateway 500C: Dead. green PSU lite doesn't lite when pressing test switch


Hi Don
first thing to check would be all power leads and fuse to clear those areas from the list. Providing all of these are correct, it looks like either your power button has gone faulty of the power supply itself. I am not familiar with this particular machine, is it a normal tower sized machine? if so then a psu replacement is relatively cheap and easy, just make sure that the replacement has all of the connections that you require.

Hi,

Most of the times, the power supply board just have dead leakages gases capacitors.These capacitors always bulges up on it top,or puff up on it top.Replaced these gases leakages capacitors will get your TV power stable,and work again.Or tries websites like Shopjimmy.com,Ebay.com to buy a whole refurbish power supply board for the replacement.


Take care in solving the problem....

I have a sharp 37" lcd tv,model # lc37sb24u. no pix or sound, power lite comes on about 10 seconds then power and opc lites alternate on and off. thanks RON


This problems very common in Sharp LCD tvs.The Tuner signal board have problems,every times the power LED,OPC LED lites up,just push the power button on again,wait see if the LCD backlight lite up and works,not the Power lite and the OPC lite LEDS flashes again.You,just have to push the power button again,sometimes u have to push the power button at least 6 or 7 times to get the Power LED stable,and then LCD backlight,come on than the tv work.Not sure,but if the Power and OPC lites keep flashing,after u pushes the power button at lest 10 or 12 times,and the LCD backlight dosen't come on and the tv don't work.I think,it time to change the Tuner board is completely dead.I have a Sharp LCD tv, I do this everytimes pushing the power button at least 3 or 4 than the power LED stable,and the LCD backlight come on than the tv work.Not a plaw in the power supply like those capacitors in many LCD models tvs,but some included Sharp Tvs is the Tuner signal board is not very good in design,use the tv awhile the Tuner signal board have problems recieving the power to it Tuner board components.

On power up the green light is on for 2 sec.


problem with the main board inside of the DS Lite. Its not staying on with the voltage being provided. To verify this. Plug your DS Lite into a working outlet and see if it stays on.

If it doesn't stay on then take the battery out and only hook up the ac adapter to it and see if it stays on.

At that point if it doesn't stay on, try to use another AC Adapter to see if it stays on, if it doesn't then you know for sure the main board is bad and you would need to get a new ds lite.

Will not boot... black screen?


Try removing the battery completely and powering it up on AC power. Sometimes a dead battery (even if you're plugged in to AC) will stall a boot-up in its tracks. If this doesn't help, please reply back and let me know if anything changed.

Green lite comes on for about 2 to 3 seconds then shuts down red lite pulses


If the back was off the board on the left is your Ysus board. It will have a cable plugged into the right side of the board from the signal board. Unplug the the Ysus board. If it stays on without a picture change both Y and Z sustain boards. If this helps let me know.
