Re: LG 50PG1000. Bad YSUS? Strange image behaviour
Hi,
My TOP Y-buffer is EBR50039001.
Company which sell me that spare Y-buffer don't allow return. Sh1t. I made some pressure to that company but without success. So as I can read my board EBR50039001 will not help you.
I share your bad luck with plasma.
I can try to sell that TV with 3 vertical lines - maybe it will be ok, for some pub for watching music channel. Or I will remove all boards and sell them separatly on ebay. But it can take long time just for refund at least...Leave a comment:

If not do you want it???Leave a comment:

Re: LG 50PG1000. Bad YSUS? Strange image behaviour
I didn't disconnect anything during charged state. I have big respect to high voltages and especially to DC. Every time I've measured voltages before disconnect anything. Between GND - Vs, GND - Va. Also I did long break between switch off and remove anything.
Panel is defective. That's life...Leave a comment:

Re: LG 50PG1000. Bad YSUS? Strange image behaviour
Guys,
my spare TOP Y-driver arrived ! I have switched on TV. I quickly checked voltages Vs (should be 193V), Va (should be 60V).. Vs is 193.3V, Va is 60.1V. So i put signal into TV and spot two problems on display.
Top part of display (about 1/8) is bit different brightness (probably due to my test with bypassed old Y-driver). Maybe it will disappear after some time.. I don't know.
Second (and biggest) problem is that i have 3 vertical lines (one pixel in width) in middle of display. Two seems...Leave a comment:

dabyd64, I have an idea for you. I have found whole PCB board here in Slovakia for 55 eur.

I will buy it, but if my PDP display on top part will be wrong I can sell it to you..Re: LG 50PG1000. Bad YSUS? Strange i...le=53613[/url]Leave a comment:

Re: LG 50PG1000. Bad YSUS? Strange image behaviour
Yeap, sure I will remove it before order a new ones. I'm bit afraid from thermal pad under IC. I have at work soldering station with hot air which is ok for removing TQFP packages, also for SO-8 with thermal pad, but I'm not sure if it is OK for those buffer IC's due to thermal pad under.
HV silicone ?? I never heard about it... I will search for it.Leave a comment:

Re: LG 50PG1000. Bad YSUS? Strange image behaviour
I fully understand your free time problem. I'm almost same, but I want to solve it ASAP as TV is too big to left it in corner in living room for long time as I live in flat...
Do you have some spare buffer IC? I need only 2 pcs. I don't want to wait 2 months for it from ebay..
I still did't remove a heatsink from buffers. Do you know what is a glue type on it? It looks like cheap hot glue stick. It should be enought isolant too.
I look over several websites offering whole...Leave a comment:

Re: LG 50PG1000. Bad YSUS? Strange image behaviour
Thanks for info. And what about your case? Did you replace buffer IC (FE3407F) ?? Did your TV works after your repair? IF yes, how long ?
I found those buffer IC on ebay, but it usually takes about 2 months to arrive to europe....Leave a comment:

Re: LG 50PG1000. Bad YSUS? Strange image behaviour
Did you repair it?
I have same TV, with same issue. I made a DATA signal bypass to bypass 2 upper buffer IC and now I have image on bottom 3/4 of display.
I'm asking you if you are success, because I heard, that if buffer IC is wrong, usually it happened because PDP display is deffective.
