I have a APEX LE3245M TV, this morning the screen went black but the sound was good.

How you would fix a black or blank screen on your TV.

1. Ensure that the power sources for all your devices (TV, digital box, VCR, etc.) are securely connected to your devices and the outlet. If that doesn’t fix it,


2. Check that your TV is set to the correct input. If that doesn’t fix it,


3. Unplug the power cord from your digital box, wait for 30 seconds, then plug it in again. Wait until the box has fully powered on again, then see if the picture has returned. If that doesn’t fix it,


4. If you have an HDMI cable connected to your TV, you could try an HDMI handshake.

Damaged component/s at its horizontal scan output section circuit. Check the LOT (Line Output Transformer) too for damage. Replace the horizontal scan output transistor. Check the input voltage to LOT. If the voltage is absent check the feeder resistor; if any. If you wish to get some details; check the site linked here. Surf the site with patience.

It will be best to replace the power supply regulator board as card basis.

try holding the hdmi wire connecting to the tv port at a slight angle, if it comes on then the hdmi connection is damaged,do you have sound?
give the connection a wiggle and inspect the connection, maybe worth a reset?

I am having the same issue with this. Did you find a solution.

we just had the same exact problem. they are sending a technician out to us. we were on the phone with them for 30 minutes.

Am Martyn...ma Tv same model did the same thing this mornign while i played FIFA 2010 world cup on PS3 Fat...what could be the problem???

why dont u just use the vga input and select vga from your input selection. it should work just fine. if not, email me back.

I have same problem, screen is blue for cable TV, same for DVD and for the S-video imput. The menues works good for adjust the color or the TV lenguages, but I can see only the blue screen.

make sure the TV time is correct. Reset the time. if that does not work, but the TV operates ok, it's in the circuit board, or could be a fuse problem.
