Hi Budm, hope you had a good week! Let me know if you would like me to include more pictures of the connector I mentioned on the post above. Thanks for all!

Re: OLEVIA 265TFHD-t11
Hi Budm! Thanks again for the help! I went ahead and created a small diagram based on your request. Please let me know if it is good enough or is missing information, if so, I will get it to you ASAP. Thanks again!

Re: OLEVIA 265TFHD-t11
Hi Budm, I hope I did not say or do something that might bother you. I really trust on your expertise and will appreciate if you can lead me to solve the problem I am having with this tv. Again, I am very thankful for all you have done for me. Look forward to hear from you

Re: OLEVIA 265TFHD-t11
Hi Budm, thanks for the reply, yes, when that wire is disconnected, I get 24vdc in all red and black that goes to the inverters on both power supplies. But when I try to turn on the tv with that wire disconnected my screen doesn't light up at all no matter how many times I power on the tv.
So you are not sure what that cable is for, is there any info I can provide to help you ?...Leave a comment:

Re: OLEVIA 265TFHD-t11
Budm, I don't want to confuse you anymore, since now I feel we are close to find the problem. Like I explained earlier, disconnecting the inverter does not gives me the 24v back.. But there is a cable that I do disconnect from the power supply and when I do it does give me all 24v back... The cable I am talking about is attached on the pictures. It is a cable that goes from the power supply to the main board, I am showing you pictures of the cable, where it gets plugged and where to the main board it goes. Let me see if you still have questions, I will try...Last edited by Fapelbaum555; 09-13-2014, 04:37 PM.Leave a comment:

Re: OLEVIA 265TFHD-t11
Budm, let me ask you a question, besides the photos I just sent you of the inverter, yesterday around 11:46pm, I sent pictures of a cable that when unplugged the power supply's starts working just fine... This cable goes to the main board. Now, I just unplugged all cables to the inverter, checked the voltage on the power supply's having plugged and unplugged the cable I just mentioned to the main board... And the problem persists when plugged. Seems having the inverter disconnected didn't to any difference on how the power supply board works when having this...Last edited by Fapelbaum555; 09-13-2014, 01:12 PM.Leave a comment:

Re: OLEVIA 265TFHD-t11
Ok, I was able to get to the inverters from the side with the problem. To the naked eye, it does not look bad... But I am not a pro.. So I am attaching a picture of the smd fuses and transformed for all three inverters on that's side. Please, Let me know what should I be looking for or should I meassure something with the multimeter? Thanks again!...Last edited by Fapelbaum555; 09-13-2014, 12:54 PM.Leave a comment:

Re: OLEVIA 265TFHD-t11
Good morning and thanks for the reply! I will check as you say. On the right looking from the back there are three inverters, 2 number 4 and one number 3. I will take pictures of the three!
Thanks again!

Re: OLEVIA 265TFHD-t11
I noticed the following that might help you, when I unplug one of the cables from the power supply board and then turn the tv switch to on, the power supply starts giving the right voltage, all the sudden the 24 gives me 24 and the 5v gives me 5v.. When I plug this cable back on, the issue comes back... Might be related? I am including photos of the cable I am mentioning....Leave a comment:

Re: OLEVIA 265TFHD-t11
I just turn around the power supply boards, left to the right side and viceversa. When I check the voltage it is still is just as mentioned on the previews post... Left side is still shows voltage just fine and right side don't... What could be causing this? Seems the problem is not the power supply, is that possible?
Thanks!Last edited by Fapelbaum555; 09-12-2014, 10:53 PM.Leave a comment:

Re: OLEVIA 265TFHD-t11
Seems right board don't read same voltage as left board:
Left power supply board:
The 24v reads at 25v
the pson reads close to 1 when off and about 4.25 when on...
Also tried the 5vsb and is at 5v...
5v reads 5
Right power supply board:
24v reads as 0
Pson 4.25
5vsb reads 5v
5v reads as 0.9
Now, something to mention is at one point I tried right board on the left and left board on the right... But no improvement... Which is a little confusing... Should...Last edited by Fapelbaum555; 09-12-2014, 10:25 PM.Leave a comment:

Re: OLEVIA 265TFHD-t11
Budm, with all do respect, I want to appologize for not knowing better, checked the multimeter and seems it was in ac... Changed to dc, and tried all the connectors we went over today.
Left power supply board:
The 24v reads at 25v
the pson reads close to 1 when off and about 4.25 when on...
Also tried the 5vsb and is at 5v...
5v reads 5
Right power supply board:
24v reads as 0
Pson 4.25
5vsb reads 5v
5v reads as 0.9
Sorry again and hope this information does takes us...Last edited by Fapelbaum555; 09-12-2014, 10:18 PM.Leave a comment:

Re: OLEVIA 265TFHD-t11
Mmm, I have been doing everything just as you asked me to, I really hope I have not been wasting your time. I did try to check the 5vsb again and as you can se in the video, I actually get some voltage the moment I plug into the outlet, but it goes right to zero within a second or so. I am attaching a video and a photo.

Re: OLEVIA 265TFHD-t11
I tested the 5vsb with the power switch off and then turning it on and in both cases it is a straight zero volts... No voltage at all... I went ahead while I was at it and tested the 5v right next to the 5vsb, and that one does goes up and back to zero when I switch the tv on and off...
Thanks once again!Last edited by Fapelbaum555; 09-12-2014, 07:07 PM.Leave a comment:

Re: OLEVIA 265TFHD-t11
Ok! Just checked, and similar experience with both boards, I plug the multimeter to the pson and it shows zero, then I press the power on button and voltage goes up and back down to zero in less than a second. I checked the max on my voltmeter and most of the times it is around 2.5 during that period, few instances where I turn the tv on and off voltage was even less.... But always back to zero.
Thanks again for your reply! Hope we are close to find out what the issue is!...Leave a comment:

Re: OLEVIA 265TFHD-t11
Hi Budm, sorry my ignorance, not sure what that is, if its not much hassle, can you please let me know? and is it fixable or total loss?
Thanks again!
