The TV will not start, as a check on the power board missing 187V, a capacitor C802 is exactly broke, I need the wiring diagram in order to make the necessary checks, which I can not find .... I hope you can help me .. .

Re: LG42PC1RV-ZJ Wanted scheme card power LGE: 67009900019A PCB: 68709M0031A / 5
I don't think you'll find one, what about the service manual with the connector pinouts? maybe you can work out how to force the PSU on?
have you tried isolating the ysus and xsus just in case the IPMs have failed and the TV is in protection?
And pictures.?
I don't have a lot of experience with LG except a 50px5d i did some IPMs on.
Edit: hopefully I've got the correct PSU and cap you refer to.Attached FilesLast edited by tw2005; 11-23-2014, 03:57 AM. -

I have already removed the card, and I found the open R810, C802 burned, ZD802 shorted, also from the solder side D808 and D853 in SMD both in short, unlike the D808 and D853 whose screen printing on both is (34 63) , for others I need to know what value to match, so I serve the schematic.Attached FilesComment

hi, wandering around the forums I found this, (https://www.badcaps.net/forum/showth...ht=6709900019A) might be fine, but do not read well by enlarging ... you could send it to me by e-mail?Comment

thanks anyway, replaced the following members of the tv work again: U801 (MR4040) - C802 (470pF 1kv) - Q801 KTC3198 with 2SA1815 - ZD802 MTZ2JB15V diode with a BZY15v - R810 (10 ohm 1 / 2w) and finally the diode smd with initials 34 63 with a BA159Comment
