Re: LG 50PJ350 plasma blowing Y-Sustain board

if you have changed gate ics, checked gate resistors and are well,my advice is to use same igbt transistor amperes 200A (30f124)bt now high voltage igbt transistor 30j127,i was getting problem with 42pj350 blowing the igbt transistor,i used 30j instead of 30f and the tv is still playing well.

can anyone advise me about most of samsung power supplies,most of them when you put the main supply and switch on the tv ,voltage drops from high to zero ,like when i test Vs voltage maybe Vs is 208 ,then it drops from 208 to zero .i make this disconnecting Z andY board for a power supply test.is it a faulty logic board or the main board itself?i really have no understanding about this issue.

Re: Samsung UN55MU6290 Boot loop

hey you all guys ,im new here but what supposed to be done there is simpleon that model ,someone can think many things about thiy issue,the cure is one ,make screen test Anupkg by removing the lvds cables,start with the rite one u will see no solution,then go to the left one the problem lies there,i mean if you are at the back of the tv ,the right side of the screen,count about 10,12,14 pins from left ofthat cable ,put a piece of tape there not so big , you will see the changes,continue cutting different size of the tape and put it ther ,remove the...

Most of the tv's I repaird are from other guys,where can I purchase new board reasonably,like this one i checked all the voltage written on the panel vs is present when ysus is disconnected and the va voltage , after checking the igbt and replaced,put the power cable back all replaced transistors went burning,why?

Re: Hisense 507D

Maybe the main board is the same as 55A7,after replacing the new main board of this tv it played well for one day, the following day when I switched on the screen shows no picture but backlight was there on,I cleaned the cables from t-con board to screen thereafter picture came back.
