Re: LG model RM-26LZ50 is slightly blurry
It is a digital meter here are the readings
For the 1117A-33CYTR
IC2
pin1 = 0
pin2 = 3.82
pin3 = 5.04
IC4
pin1 = 0
pin2 = 3.29
pin3 = 5.08
IC601
pin1 = 0
pin2 = 3.29
pin3 = 5.1
For the chip marked IC3 which is KIA7027AF3

Re: LG model RM-26LZ50 is slightly blurry
Sorry for the delay but unfortunately not all the chips are marked the way you described.
I was able to get hold of a service manual and part list for that circuit board.
It was from LG with the same chasis...ML-041A
I will use the circuit board number and give you the chip number. here is an example
IC2, IC4, IC601 all used 1117A-33CYTR, but on the chip was B533399GC
Pin 1=5v
pin2= 3.2v
pin3= 0v
Will this be ok
After collecting all the data something did jump out at me it was
IC3...very...Leave a comment:

Re: LG model RM-26LZ50 is slightly blurry
Thanks. It's hard to see the part numbers on the regulators. So I was looking for a parts list fro the board but no luck.
What did you mean supply the list in the suggested format?
Pin 1
Pin 2
Pin 3 ?Leave a comment:

Re: LG model RM-26LZ50 is slightly blurry
I was able to get a dvd player with a HDMI output and used the hdmi to dvi cable to connect to the TV. Picture is perfect!!
Do you want the pictures of the main board?Leave a comment:

Re: LG model RM-26LZ50 is slightly blurry

LG model RM-26LZ50 is slightly blurry
Need help trouble shooting. I got this tv from a friend and the picture is distorted just a bit. For instance when showing numbers you can make them out but it is not aligned as they should be.
So far I have tried another cable outlet and also used a DVD player and got the same results. From what I have briefly read here, it might be the Tcon board, but any other insight would be appreciated
No activity results to display
