Hi I have a 32LG3000 TV and it is showing a flashing red light and will not turn on. I have pulled the plug out etc but no luck. Can you advice? Marion


Hello,

You need to check the output voltages of the power supply to see which one goes off. It may be due to short circuits some where, if otherwise, power supply board is dead, u know basic electronics' and soldering? Most of the times, the power supply board just have dead leakages gases capacitors.These capacitors always bulges up on it top,or puff up on it top.Replaced these gases leakages capacitors will get your TV power stable,and work again.Or tries websites like Shopjimmy.com,Ebay.com to buy a whole refurbish power supply board for the replacement.

Take care to solve the problem....

My son dropped my 32'' inch LG lcd tv now it won't


It probably has a cracked circuit board. If you want to repair it on your own open it up and see if you can find where that cracked section is and see if you can resolder it back properly.
