Title: HELP LGLP2637HEP PSU component list
Post by: cheeky2 on August 05, 2012,08:36:04

Have a completely non function psu board for a 32inch LG 32LX2R-ZJ replaced a couple of components already however looks like there a few more so if anyone has a list of all the parts or schematic then that would be great?

So far replaced FR501,  STRW6251 and ZD504 (found faulty not yet replaced) anyone had any experience with these psus? Any help welcome
 I know these psus also suffer from dodgy caps but as no ouputs will check them out later on (none bulging).

Thanks :)

I have the schematic of the unit however the power board is not included with the schematic! I have been looking at the psu board and it looks like the cct that is defective is associated with the 5V standby. Just about to get a 22V zener for it which will hopefully bring the 5V standby into action! The original one shorted out!

 The power supply kit i believe is only the caps and not any other parts.

 I will let you know how it turns out :)

Hi Cheeky2,

Had one or two - PS  Yuyang YP2632T - my probs were only C214,C221 and C222(all 1000/10)

Hope to hear of your success -

All the best - Chris.

SUCCESS    :yahoo:
 Finally managed to sort it out after replacing 10V zener diode zd501 which brought it back to life :)  :72:

 I had to take a picture of the diodes and then blow them up to view the component parts numbers. Once this was done it was far easier to identify the components.
 Parts blown were STRW6251, FR501(5 Watt 0.16Ohm resistor), zd501 (10v zener diode .5W), and zd504 (22V zener diode .5W).

I entered one LG37LC2D with power supply capacitors LGLP2637HEP damaged.
accidentally when I'm changing a capacitor SMD resistor R163.
can anyone help me telling me the value of this resistance.
this resistance is in the welding face in parallel with the capacitor C161 of pin 7 of the IC U100 (F9223L)
attached photos of the position.
THANK YOU
forgiven for my translation
