LG 42PC3RV module LGEPDP burned hybrid IC

TV is LG 42PC3RVI found burned module LGEPDP 060908...fuse FS1 burned and hybrid IC2 was in short. Voltage Vs=188 V and Va=60 V...OK.
I changed all module but immidatly after replacment and switching on hybrid IC was burned again !!!
I measured resistance beetween SUS electrode and the chassis-but it doesn't show any short. Resistance is very high.
Is it mean PDP is faulty?

Model? what if any lights on front of set come on? If total dead unplug and look for fuse connected where power cord enters set, as much as I can suggest without more info.


This is an indication that you have a short on the power supply section.

It can't be fixed by replacing the fuse alone. I've suspected that you have a short on the following parts :

1.Power Cord - even very low of chances but still to be check.This is due to frequent bending and pulling.

2.Rectifier diode

3.Main filter electrolytic capacitor

4.Voltage regulator I.C.

This is the common parts that might be shorted and made the fuse blew. #2-4 is quite technical and need an expert to do the job so I

Green light is on, fan is blowing but we know longer smell the ozone from it; we have just changed the plate & cleaned it?

You probably have a burned out high voltage transformer. That's what produces the ozone. Helpful hint...........the high voltage transformer is also the one used in bug zappers

I have a LG 32LC2R flat screen tv and lost my manual while moving house, is there an electronic one I can download

here is a repair manual for your tv .. its in PDF form


the pdf download is about half way down the page

below is a site where you can download the User guide



Burning smell and dark screen

Needs new hybrid ic on ysus board. There was probably a short in it somewhere.

If the tv is worth it, a new ysus will cost about $50 upward.

GLI PRO preamplifier fuses burn

You shorted the main semicondutors and they have now got a short on them, so they are acting just like a piece of wire and drawing too much power so the fuses blow. You need to replace whatever is on the main heatsink. Did both channel wires make contact or just one? If only say the right did you might only need to replace the right side parts, unless it is an IC doing all the work!

Z sus board fault

When ever either the Z or the Y main goes out, all of us service co's replace the Y main, Y up/lower drive boards and the Z at the same time. Now you will have to start all over. I just had a Samsung 50" that required all 4. It is a must with Plasma sets. Hope this helps.

I have a Vizio P50HDM. The old "pop of death" occurred again which is the second time in less than two years. The repair shop replaced the y-sus board the first time but I am being led to...

Hi, i just got thesame problem as you do! The zsus board situated at the left corner when behind the tv is usually the cause. Apparantly the Hybrid IC yppd-j015b could be damaged since it is the recipient of the approx. 192v DC. There is a fuse which protects it, but at times goes off with it. It is usually caused by overheating and in my case, i took a closer look underneath the Hybrid IC and found tinny 'tainted sparkles' on the heat sink which was caused by one SMD (surface mounted device)capacitor. This caused a spark, or what many call ''POP OF DEATH'' ,- a short circuit , 192V TO GROUND, the heatsink!
Infact, when the person who owned the tv complaint of hearing a pop sound, when i opened the tv myself and switched it, i could see that it came on, there was sound, faint picture exactly as you described but as i was gazing, i SAW the spark, again but this time even the faint picture disappeared.
It was a good thing that i saw the spark! Now what had happened was that the first pop did blow up low value smd resistors and MOSFET smd in the Hybrid IC yppd-j015b but kept the tv on with no picture so the second time i saw the spark made matters worse, the fuse went off and other MOSFET sms (s).

Now in all of this, you have to have more than basic knowledge of electronic repairs to even start opening the tv because of many reasons:.Anti static components, MOSFETs,etc just to remove the yppd-j015b hybrid ic without the proffessional desoldering equipment, feels like battling with a puckupine! Because of lack of proper desoldering equipment, most technicians advice people who dare try to REPLACE the Z SUS and Y SUS boards.

If you can, just make sure you replace the bad parts yppd-.... included and place anti heat isolation underneath the ic or add two more super quiet fans to cool off.

Before replacing parts, take very close looks at the surrounding parts for physical damages and test if not all resistor and diodes arround for shorts.
