Take off the back cover of the TV. Be careful around the red wire that suction cups to the top of the CRT - it carries high voltage! On the circuit board, you will see where the power wire connects to the board. You should be able to pull the board out to get to this area. Also, the board can be completely removed by disconnecting a few connectors and gently pulling the board off that connects to the back of the CRT. When disconnecting the high voltage wire from the CRT, there are many resources on the web that discuss the proper way to do that.

The diodes are near where the power wire is soldered to the board. You will see a fuse (which needs to be replaced - just pry it out and drop in a new one - Radio Shack sells these). Then if you go toward the back of the case, you will see some other electronics and then four diodes. They were all black in the one I worked on. And the number on them is in my original post, I don't remember it right now. Desolder one at a time noting its orientation - diodes must go back the same way, and check each one. I used a multimeter that had a diode check function.

Good luck.

Tv wont come on it sounds like its powering on but


1. Your primary side of the power supply or power regulating circuit.
2. Your TV is in need of service.
3. You will need to go to a certified TV Tech to diagnose this issue.
4. this could be the power regulating transformer in the circuit or regulating diodes in line with what are called bypass capacitors. Techs will know then as filter caps.

Here's one place to get the remote for the TV;

The Directv web site has only one code to try for the ILO TV. 10171
Does that code work on the TV?

ILO 27' LCD TV Start up problem.


depends on what "start up" problem you are having. If it is turning its self off upon turning it on, you need to go to Radio Shack and get a $2 pkg. of diods for the power supply--it's fixing to go out; we could not get any help and figured out what it was and fixed it ourselves since Wal-Mart was useless and had NO customer service.

Ilo 32hd blown fuse


Diodes are often parallel to other components so if one measures 'bad' it should be desoldered on one end and checked again.
On the diode test position of most all digital meters, they will show between ~400- 900 depending on the type if the lead polarity biases them in the forward (conducting) direction. The indication isn't really too meaningful but roughly equates to millivolts of voltage drop in the forward (conducting) direction. Reversing the leads, especially on the diode range should just cause an over-range indication or the same as when the leads are not attached to anything. Shorting the leads should show very close to all zeroes.
