I have this one with a power supply repaired by a different repair shop and the problem I am having is powers up gets sound no video. I have verified that the vs is 217v and va is 55v but both drop to about half that. If I remove the cable to the y main from the logic main I get vs and va steady. VE is 13V and should be 103v and vsc i -1.6v should be -195v. I could really use a service manual right now if anyone has one they can share or a comparable model service manual. A little more information is the customer did change out the power supply but it did not fix the issue so he put back in the old ps. Now I am wondering if I am running into a bad ps and y main.

Re: samsung pn64e6633d2f
if you disconnect the ribbon between the main and the Y-sustain does the vs stay where it should? If so bad Y-sus
3 blue caps need replacing. Its the 3 caps to the right of the yellow transformer.
Also you have that test written in sharpie on the TV. Have you already done it?Last edited by Nick's Tvs; 01-07-2017, 02:50 PM.Comment

Thanks for the response and yes I have and Yes it does stay where it is supposed to and yes. I have replaced the y main with a board from shop jimmy and no change. I am thinking that the bad power supply may have damaged the y main and now I have two problems.Comment

So you are saying to replace the three caps to the right of the yellow transformer. I presume the ones marked 106. Do you know the value of the capacitors?Comment
