Will not turn on


Fault with the main power supply regulator board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts.

It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and precious time.

Why wont it turn on


Most common problems with modern LCD computer monitors and LCD,LED tvs are it power supply boards have dead and dying capacitors components parts on the power supply boards.That the board u alway check it first and throughtly for dying and dead capacitors components parts.That the board where the tvs or monitors A/C power cord plug in it.U have all the basic tools also u can do soldering works and understanding basic electronic components.U should by replacing these dying and dead capacitors components with no problems at all.But when u are replacing all these dying and dead capacitors components parts that are bulging up and busting out of it normal cylinders bodies.Replacing these new capacitors components parts alway up the voltages higher in these new capacitors components parts like 5 or 10 voltages higher will stably the power supply board alot better and don't put out to much heat for the capacitors chemicals make up to handle.If u can not do basic soldering works and have all the tools or understanding basic electronic components theories.Tries websites like Ebay.com,Shopjimmy.com to buy a whole new refurbish power supply board for the replacement.

Tv will not turn on after a power outage


Hi Filipe,

It could be just a blown fuse on TV. Please go check and replace with new one if it busted.

Hi i have a 40inch bush tv my partner was using this for his computer screen last night like he does all the time but for some reason it turned itself off and now wont turn back on. The standby button is...


Is there anything power signal lights?If there is no signal power lights,it is totaly dead set no power.First step is to check the power outlet,then the AC cord if there's a ac power.If the AC cord is good,check the fuse,located at the power supply.Replace same value of fuse if busted.Try this sugestion or procedure.Thankss...

My CDJ 850 won't turn on.


If the standby light blink then it indicates a fault relevant to the processor.If the set is fully dead then the SMPS power supply can be faulty.

http://www.fixya.com/support/r5826301-working_switch_mode_power_supplies

Since there is a possible short or leak in the circuit the output driver section can take in huge current to trip the SMPS or from advice from the micro processor. Remove the power plugs and make sure that high voltage sections are discharged of the potential stored in capacitors. Look for visible signs of leak or of busted capacitors. Look for bulged capacitors or damaged components- burnt or busted. Use a multimeter to check the continuity or shorting in components, if so detach from circuit and test . If the voltage builds up and the set power ON and then shuts up then the suspected section must be checked in detail.

The processor must have the +5 voltage to the function properly , the +B and secondary voltages also must be checked to infer the fault. Trace with caution and in running through the signal path , circuit trail.

The lights do not come on when plugged in


If you have a volt meater check the power supply to see if it is sending the correct power. If you get a rating more that 5 volts above or below the rated voltage you have a busted power supply. If it is above 5 volts the router is most likely dead.

If you don't have one try to locate another 12v (or whatever its voltage is) power supply.

I have a belkin N1 router V4000 We had a power outage and not it won't turn on again. This happened once before and I thought it was dead but somehow I revived it but now I can't remember...

Im getting no power whatsoever heard a pop last time i turned it on now nothing


The tv power supply board it is dead.That the board,where the power a/c cord plug into it.U have all the tools and understanding basic electronic also can do basic soldering work?Yes,take ur tv aparts.Check the whole power supply board carefully,by replacing all those blown capacitors that are busted open and all those capacitors are dying going to dead like bulging up or puffing up on to it tops.Replacing all those dead capacitors to a those new capcitors,do some modification of the capacitors parts like by replacing it in the same Micro fered,but the voltages should be 5 or 10 higher than those old busted or dying bulging up tops capacitors.By replacing all these dead capacitors and dying capacitors with a higher voltages capacitors.These capacitor to have a better chances to take more heat resistance,while tv be watching for hours of using.The tv should have power and work again.Or tries websites like Shopjimmy.com,Ebay.com to buy a whole refurbish power supply board for the replacement.

My tv is dead , nothing at all , no sound-no lights nothing


that problem is in the power supply..

try to open the cover then look for the power supply if you see the power supply try to see inside then look for the fuse if busted?if it is busted check all the possible caused like power transistor called regulator.diode,transistor check if it is shorted..and also look for the leak capacitor and open resistor when you find defective parts replace it and finally try to test it again

please rate my answer if it is helpful thank you
