Hello, I have a LG 42LH50 television with a cracked screen. The unit will not power up. I am trying to find a circuit schematic for this item but LG has been vary unhelpful.

If anyone has a schematic or a good link to find one I would greatly appriciate it.

Also, does anyone know if this television will powerup with a broken/cracked screen?

 

Hello,

What kind of screen is it?
LCD, plasma or crt?

Perhaps browse this site for some schematics:

Thanks bertus. It is an LCD.

 

42 inch LCD

I did some internet search time and qot squat. Owners manuals only.
Maybe a seller like Sams? or am I showing my age?

 

I searched online, and made a few phone calls. Sears offers a user manual and a parts breakdown (not including the board). LG said that they could not supply me with that information for "liability" reasons...

 

They want you to pay retail at an "Authorized Service Center". (the dirty no-goods)
Good brand not to buy, I see.

 

Yea, they were quick to make that recommendation

 

Pay retail or don't buy LG?

LOL!

 

Hello,

I do not know what chassis is used, but you could try the link to the 47LG5000:

(there are multipart rar-files, put all in one directory and use winrar to unpack).

If you have the chassis number, you might try to see if Sams Technical Publishing has a Photofact for it. I tried the model number you supplied on their site, but no results.

 

Its an interesting dillema geting service info for TVs & the like. When iwas repairing TVs & VCRs 8 yrs ago if you was a service agent they were avalable, some companys sold them others they were free. Since bI wasnt a service agent there was a company which i joined for free & i could hire the manuals. Usually i photo copied relevant info & returned the manuals. If the manual was lost you paid forit. The legacy now is a small mountain of old service info & manuals from a service colegue who has died & my leftover stuff. Probably finish up as recycled paper!!

 

Quick, sort through it and send the LG stuff to oidium!

 

Well, I appreciate everyones attempts. Thanks!
