Did you check to see that there is AC going in to the supply board?

Did you verify that the standby supply section is operating the uPC for the set's operation while the power is in the off mode?

If the uPC is being powered, did you verify that it is actualy operating properly in the standby mode? This is so that it can monitor the power on/off condition.

Some other things to work out:

The fault can be any one of the other boards in the set. They all work off the power supply. The supply is uPC controled and it is very critical to the specifications of the operation of all the boards in the set especialy for power consumption and for safety.

This is the reason that when trying to service these sets yourself, it may not be feasible. At home or in a small shop you would not be equiped to make proper diagnostics on each of the boards to determine their performance and current consumption.

If one of the other boards has a critical short on it and the power supply does not go in to protect, there is a possiblity that the new power supply may be damaged. I have seen this before.

My 42 wide-screen LCD T LCT42HA36 will not come on

Replace the power supply if you suspect it or look at it to see if any puffed up caps on that board.

I have a 42'

More likely the backlight inverter board has gone out, or power supply for the inverter board went out, those are the two places to look. Check the power supply first for burnt parts, bad capacitors.

Lost remote 42 ilo cant find code for universal

Same thing happened to me because I bought an Insignia television and I couldn't find any universal remotes to replace it. It just happens when you buy an off brand TV.

Try these:

http://www.xdiv.com/remotes/ (look in here) http://www.comcast.com/corporate/customers/customer_support/remotes.html (look in here too)
Ilo HD32 code is 11630
Others are: 11286 11684 11990

32inch ILO LCD ...Shutting off

It looks like the power supply is failing on your TV. Some of the components are starting to fail after the TV warn up.
You can try contacting the manufacturers and ask them if they could Honor the 1 year manufacturers warranty by giving them the model and serial number, or hopefully the can repair by taking the date when the TV was manufactured.
I service these power supplies.
Let me know if you need further assistance. my email is [email protected]

ILO LCT27HA36 No Manual

This is a very low end low quality made TV set. I would suggest you take it back and see if you can exchange it.

From my experience, I would suggest getting a good quality brand name TV set. Most of the Sony LCD TV sets have earphone jacks, external outputs, and come with a full set of instructions. They are also strongly supported for service during the warranty period.

42" ILO Television Problem

same here model lct42ha36 for less than 90 days some say you can take it back to walmart, hurry. you can call ilo at 800-216-5156 with model and s/n and they will give you a number for akai 800-428-1105 or tatung 888-428-1105 to call depending on which made it. I called akai and they had me fax a copy of receipt and the transaction number they gave me to set up a in home repair by a service center at no cost they say (i hope) it is cover for one year parts and labor and you can go back within 90 days and buy extended warrenty for 2 more years for about $60. I'm over 90 days so i'm going through the process. Repost to this site and let me know how it goes. I'll repost if I can with a follow up when they come out.
