Lg tv ticking

There is some shorted component/s in the circuit board. The short circuit protection circuit detects this short, and shuts down your TV again and again. That is why you hear these 'tick' sounds repeatedly. Contact any experienced service technician to get your TV repaired. The work is skilled one, which need sound knowledge in electronics, and work experience.

Sound is making a ticking sound and the screen is just dark

This sounds like you have had a flyback transformer failure and the ticking could be the protection circuits preventing the TV from starting.
As TV's have very dangerous voltages present internally, take it to your local TV repairman.
It is not worth the risk of attempting this type of repair yourself unless you know exactly what you are doing.
Even if this is a simple failure, those voltages are still present and I would not advise you attempt anything yourself.

Shows for one minute then goes tick, tick and shuts off

ok try this , unplug the front control board , if it stays on then thats the problem , but if it don't , then you will need to check the components around the EEPROM and resolder all components that heat up, it is possible that the crystal and EEPROM may need to be replaced but doing these other things plus a couple of more checks will help find the culprit
also make sure all work is good, resolder and recheck are the best way to eliminate any problems
please give a fixya rating so that i may continue to help you if needed , thanks

No picture, then no picture and no sound

if your could hear a slight ticking (tick-tick tick) or whining then some electronic component might have been damaged (shorted). if you have no experience repairing electronic equipments then i suggest you to send your TV to a service station!

Tv won't turn on

Most likly it is a problem in the power supply regulator circuit. pretty common for Toshiba TV sets. If you know about TV serviceing, first thing to replace would be the regulator IC as that is the problem 80% of the time. if that does not help then you will need a schematic to trace out the regulator circuit. Good Luck PS please dont forget to rate this thread.

TV starts but Does Not show picture or no sound

The Tic Tic sound is a result of the high voltage shutdown circuit. Thats what the circuit does if theres a short in the Highvoltage sweep. like maybe a shorted horizontal output transistor??. The only way to really tell is go in and measure the start up voltage and if the Hivoltage comes up and shuts down its a fault in the shutdown or Hhv regulation circuit . if it dosent come up at all then the faults in the Horizontal sweep circuit . Hope this explains a bit? good luck
