The protection LED on the amp is always on.and the green is off
I have an MOQ-vanquish 1200Watt amp...there were two 220uf,16v capacitors blown..I replaced them with 220uf,10v...and the amp started working. But the red LED, next to it written protection is on but the the amp does not work. It never actually worked since it was given to me by a friend..could it be that i used a different cap?please help..couse I wana **** up ma ride yo..

for using FixYa. On the Deflection board there are
3 capacitors CP 114, 120 and 150. If any of them is puffed up on top replace
all the 3 capacitors CP150 2200UF 16 other 2 are 220UF 35v they will be green
with gold writing on them. Resolder all pins on Fly Back Transformer (FBT)
also. FBT could be in the power supply. Check the SMPS and in any event
replace CP 120: 330UF/35V/HF & CP 150: 2200UF/16V/HF (May be bulged or vented)
Always Resolder Cl031 & Cl032 (usually looks ok on visual inspection but
common to ring crack).
Please do accept the solution if
the issue is resolved or else revert for further assistance. Thanks Rylee
ON the Deflection board look at cp150 (2200uf 16v)- if it is puffed up on top it is bad replace it and 2 more cp114 & cp120- 220uf 35v. Radio Shack should have capacitors. they are green with gold writing on them.
I would suggest looking at the capacitors on the power supply board. I just got one today with 3 blown caps (the tops are swollen) and a couple missing components. The ones blown on mine are the 220uF @ 25V and 1000uF @ 16V.
This is a generic symptom that could happen to any LCD
The following is a generic answer applicable to most.
The most possible causes are bad capacitors or a bad
Open the unit and check to see if any of the capacitors in the power supply or
other boards look domed or vented on the top.
Replace any capacitors accordingly. Use the same value capacitors. Most often,
1000uF 16V or 25V, 470uF at 16 or 25V, 220uF at 16V or 25V.
If this doesn’t solve the problem, try checking the surface-mount transistors
on the inverter board that run the lights. Some times these transistors go bad
and can cause the power to cycle up and down. Check the area for any cracked or
overheated ceramic or mylar capacitors.
Don’t forget to check for caps on the main board. Some times these boards are
overly simple and only have a couple of caps, but other times they are teaming
