seems like bad capacitors or dirty connection.

Re: LG plasma tv behaving very odd

hi i am updating this thread ...its no longer valid

will create a new one after further testing

the previous sound and video issue appears to be the dvd player....when i got good voltages on tv i then was like whats causing the sound to be bad and after messing with dvd player i found out the connections are bad on the internal board which caused funky sound and video...as shown before...

i bought the tv for $10 guy said it stops working after 15 min

i have had it on for over 45 min with perfect pic and sound...via dvd player...will continue to test....i get good 195v and 60v and 5v outputs and inputs to y and z boards...but there is one bulged cap at output ps to y board 3300uf 10v and 1 bulged cap on z board 150uf 100v....but until i get the tv to not work as previous owner said i cant figure out the issue...

im sorry for all the previous posts....

Re: LG plasma tv behaving very odd

via different dvd player

Re: LG plasma tv behaving very odd

it goes to show you...you have to check the basics first......never would have thought it was dvd player causing the issues but i started using common sense and adding things up and it just didnt make sense so thats why i then tested the dvd player i found out sound and video were both defect...

Re: LG plasma tv behaving very odd

ok update

i replaced the cap on the z board and ps and made no difference

it now seems even worse

i can sometimes get an image when i hit menu button but now all i get mostly is just weird outlined colors as shown in my previous pics

i get good voltages coming from ps

Re: LG plasma tv behaving very odd

if someone had to guess by my photos in post #20 with the odd outlined color image....would that be a z board symptom or y board sysmptom?

sometimes the pic is fine but now most of the time the image is funky looking like the pic on post #20 here on the right

Re: LG plasma tv behaving very odd

hi again....i just checked the heat sinks on the y and z

there are 2 ipms on each board ..

on the z both heat sinks are warm

on the y one is warm and one is cold

tv has been on for 20 min..

my question is that if one of the ipms is faulty on the y...why would i get a good picture sometimes....or could there be an issue with power to that particular ipm...or is this normal if an ipm is going bad....

i know the ipms going bad is very very common
