Stay always black and I heard a blink noise over coils on PCB


The capacitors have failed. Don't put power on it! Replace the swelled Capacitors with the same Value and Voltage and Size. Those bad capitors will cause a myiaid of problems.

Tv will not turn on


It sounds that there is some short circuited component/s at its main power regulator section circuit board. Contact any service technician. Products powered by electricity should be serviced or repaired only by experienced professional technicians. Any attempt to service or repair the product by anyone else could result in serious injury or death. If you are not familiar with electronics, do not attempt to repair. Whether you suffer fatal electrical shock. Instead, contact the nearest service center. If you wish to get some details, http://electronicshelponline.blogspot.com/ Pull up older posts.

If you have any one of these LG Models TV below, and all of a sudden, the screen lights for only a few seconds, then goes into standby with a clicking noise. [Stuck in standby] When you try to switch it on, it tries but then just clicks and goes back to standby? In this video, I show you the components that goes bad, and the culprit that causes it all. The power supply board has already been bought from Ebay, but I'm still selling the voltage regulator that is dang near impossible to find on ebay, as well as the REPAIR KIT for this power Supply Board. Board model number EAY60968801. With any one of these PCB # EAX61392501/7, EAX61392501/10, EAX61392501/11, or EAX61392501/12 Please Make sure that you've already gone through the process of troubleshooting and testing your tv's power supply board before making any purchases.. I recommend that you get a tv tech to check it out, because every tv is different. Remember, the component, and the repair kit will only repair power supply model (EAY60968801) with the appropriate PCB numbers. You buy at your own risk

It keep blowing up the fuse on pcb ***,y main power supply, we have changed the board twice , first time it worked for a week and second time for 2 hours before blowing up the fuse and probably the board,...


There must be another component which is causing this to happen IE/ The compressor, capacitor, fan, reversing valve coil or perhaps it may just be a damaged wire shorting somewhere. You will hav eto go through each component with an electrical test meter to ascertain which one is faulty... Good luck. Until then , i wouldnt go out and buy another board...it will blow that one as well...

Hi tv comes on then go to sb no picture if control pcb is disconnecte s/b light stays green volts ok have replaced control pcb z sus was short and have replacecd


Hi,

I understood that the TV goes on protect mode (standby) when the control pcb is connected.

Please provide details on TV model and details on control pcb. If control pcb is a control board with touch button , look for components shorting with the chassis. If you are talking about digital controller board (big main board) then one of the parts connected to board is faulty.
