Hi I'm Ray and I am a fix Aholic,I am working on a LG 42LV5400 side backlit tv.No sound or Pic. Getting only 36v to leds(there is a strip on right and left side)Power light changes from red to blue when button is depressed. From reading the legend on the main board voltages seem ok,standby and others.I disconnected the cables to the back lights to see if voltages would go up,but they stayed the same 36v. Pulled out led strip and put 9v to each one and they all lit up,heated up main board to attempt to possibly re solder a cold spot and hooked everything back up,still no backlights.I need to know what the voltage is supposed to be going to the leds,can not find anything for this model.
Not sure if I am doing this the right way of posting this here,but I never done this before,not even sure where to look for the reply,hope to find an answer on this electronic highway

Hello,

Name is Joseph, from the province of Rizal, Philippines. I was referred here by a colleague (killpatrick) in search of a possible solution to my samsung tv (fading video).

Hi Everyone! I've used the forum before and found it very useful for fixing my HP 27" monitor.
This time I've got a Samsung TV that I can't figure out yet! Would love some help, so I'll start a thread.

Hello, My name is Richard, I just joined and I hope I can find a solution to my TV problem in this community. I have yet to open the TV, so I have no idea whats wrong, but to describe the issue, the left and right side of the screen seems to have flipped over to more or less an inch and at the just near the bottom part of the screen there is some discoloration and horizontal lines.

Hi. My name is Karlis. I am just a novice in wast fields of electronics and I registered to this forums regarding audio electronics issue about which I have no experience.
Although I registered only to fix this issue, I intend to stay in this forums for long time as this seems a nice place to discuss topics of my interest.

Hi, my name is Adam.
I first got into electronics when maplin had the old diy soldering kits and over the years I got into repairing pcs and other electronics.
I recently started doing component level repair when the company My job outsourced to consistently disappointed (i’ll retain the names of the not so innocent )
Now I have a proper workshop and am learning many many things as my new company grows.
Hopefully I can add some useful content to the forum.

As a newly qualified TV Technician I used my wages to buy one of those newfangled computers, a Sinclair ZX81 and to make it really special I also bought the 16K ram expansion pack, Pong was great. I guess that says it all
