SOURCE: LG 32LX1D 32 not turning on

Hi, I think you have to get it checked out by a profesional, unpluging your appliances is a good idea but damage can also ocuur the moment you plug them back on. If you want to try it could be that a fuse is open there not normal fuses inside (small chip fuses surface mount)

SOURCE: tv turns off after 15 minutes of use

For bobby11 and luis, it is the power supply. Part Number EAY34797001 in the 42" and EAY34796801 in the 32". This is a known problem, and somebody should start a Class Action against LG over this one. Part is available online and easy to swap out for anyone with the most basic knowledge.

SOURCE: MY lg 32lx1d is not turning on..

I had the same sympton on my tv...it worked fine one day and the next day it would flash a green light a few times you would see the screen power on, but still be dark then the power light would go red. I couldn't do anything on the tv no menus or sound. It turned out to be a bad power supply, a new power supply will run around $200-300 - in my opinion it wasn't worth fixing. My neighbor was able to fix my tv - he repairs electronics - ended up cost me $100.00 - its been running for 7 months now no problems so far...I can have him fix this for you if you are in the area - shipping makes this to expensive..he is located in south jersey...or you can try a tv repair shop ( i called for this but they wanted between $75-100 to just look at the unit + repair cost - i would of been back to the 200-300 range) let me know if you need help...John

You may have 24vdc (for backlight)/12vdc (for sound) power supply problem or backlight inverter board problem that causes the 24/12vdc power supply to shutdown.
You will have to do in-depth troubleshooting by taking voltage measurement before and after it fails to work, look for bad caps first to see any sign of leaking/bulging tops (notes: not all bad caps will have leaking/bulging tops).

If you are going to DIY and have proper tools, electronics knowledge, and know safety precaution then please read on:

Problem with my ASUS W3J also with BIOS.


Sounds like your hard drive is toast. Replace your hard drive and try again. If it continues, it may be time to replace your laptop.

Also check your recovery disks for heavy or concentrate scratches.

Monitor goes blank less than a second after turning on.


I start my computer and turn it on, and everything looks fine for about 1/4 of a second and then it goes black while leaving the power light green. I can only see the screen again after turning it off and on, but that's only for another 1/4 second. What's up?
I got my rosewill flatscreen as a hand me down from my father. I've had it for several years now. Was working fine until a month ago. When I turn the computer on the screen goes black after 1/4 of a saecond. I have to turn it off and on anywhere from 10 to 20 times before it stays on. I have checked all plugs to the computer and outlets. I have absolutely no idea whats causing this.
