What is the reason for my E701i-A3 failure? All boards were replaced, worked for a minute, and then had the same "fade to black" failure as the first time.

Your back light controller board or the ballasts for them may be bad if they weren't incorporated into the power supply board.

TV turns on then off no picture

this is very common. it is the power supply going bad. it should run at 130 volts dc. but it is now running much lower that this. just enought for the tv to come on. but not enough to power all the circuits right.

Kdl-55ex620 red light blinks 3 times

Unplug your TV from the AC power. Press and hold the power button on the TV itself for about 10 seconds and then release. After another minute, plug the TV back in and press power once.
If the blinking is still occurring then this unfortunately indicates a failure within the TV and will require a service. If all OK then happy viewing!

If your LCD TV or monitor has stopped working, or is displaying one of the following symptoms, then it's a candidate for some new capacitors
- Flickering screen
- Screen image disappears after several seconds
- Dim screen
- Slow start
- Power LED on, but no picture
- Unusual colors and/or lines
The primary cause of LCD TV and monitor failure is caused by faulty capacitors. You can examine the capacitors in your LCD TV or monitor and actually see if they are bad.
If they appear bulged on top, then they need to be replaced.
New capacitors will solve a host of problems in LCD monitors and TV's and will extend the life of your monitor or TV by several years.
?Check the cables, connectors and connections.
Take it to a repair shop.

Having problems with the sound on the 37z3030d model, it was working fine but now crackles all the time and cannot find the manual

Look for any loose contacts in RC jacks, cables and connectors. Also look for any fungus growth in connectors.

First of all, sorry for the mix up on model the model #. I was viewing a problem regarding LG LCD TVs and found your link. My problem is with an LG 42LGX LCD HDTV. It has worked fine without any issues...


welcome to fixya and thank you choosing my service..

OK,that is the most and common problem of all LCD TV...

Usually dim and totally have no back-light is cause of bad inverter board.One of the inverter board is shorted that cause dim light and crackling sounds..

This are the sample images of inverter board.

to make sure that the problem is on the inverter board kindly try to disconnect/unplug it from your TV and power ON then observe if the crackling sounds remain or not..If the crackling sounds gone replaced the inverter board..Also I need to how many inverter board you have? if 2 or more disconnect it one by one to determine if where is the specific faulty inverter board..

I disconnect #1 inverter still have crackling disconnect #2 inverter and reconnect the #1 inverter until you found the faulty one..Note when you doing this make it sure you power off the TV before you unplug or disconnect inverter board because its high voltage..

I need the picture your TV screen..just send it to
