LG WN8122E. No picture. Screen comes on momentarily, relay clicking at the back and then goes dead again. Reading forums it seems like a common problem. Is it repairable?

plasma tv are common, you may need to replace the capacitors on the psu or any other capacitor, look for damaged capacitors and replace for exact part number ie. 400v 330uf make sure they can handle 105c as the boards do get hot. dont keep turning on the tv as you can cause more damage.

It sounds like the main system control memory IC to this TV is faulty. 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.

My LG 50pg3000 will not turn on, it just keeps clicking like it is trying.

The clicking is most likely a mechanical relay in the set's power supply and points to a issue there.

I have a 2006 LG 42PC3DV Plasma TV and everytime I try and turn it on it makes a double clicking sound and then turn back off..any reason why?

try to test the relay,, or maybe the capcitor, diodes in power source section with your multi tester,, and i think, there is a thermostat beside power that leaks or defective maybe,, then try to change it..

My refrigerator doesn't seem to be cooling properly. The fan and blower are still working, but you can hear a click once every 5 -10 minutes. When you take the screen off the back of the refrigerator...

A relay starts the compressor with a higher voltage and then quickly kicks out
It does a lot of clicking (trying to start over and over again)
If thats what is happening with yours
Its best for a tech to replace The relay but you can do it
Take your model number to your Local Appliance parts store they will have a diagram
showing you how to install the relay. Its called a hard start relay
I use part no ERP410 POWER START RELAY, CAPACITOR AND OVERLOAD all in one. (110 v)

We have an LG tv 42PC3D when we turn the tv on it clicks on and off and does not turn on. We pulled the back off and the clicking sound was coming from a circuit board # 68719PT299A.

u have power problem. it is the mechanical relay clicking. it tries to turn on but since there is power related problem, it auto turns off again. it is the way they are desinged to prevent further damage. any LG service centre can replace the board or a qualified tech can repair.

My 37 in lcd lg flat screen just keeps clicking on and off and never actually turns on

Something is stopping the relays from starting up the TV. This will be a fault either in the power supply board or the microprocessor ICs or with the inverter board. This would need to be taken to a service repairer to diagnose the problem.
