Please help I'm loosing my mind 65" tv

Hi all I'm new to this sight. First off I have a olevia 265 that was given to me it worked great every day then nothing. So here we go I plug it in and the blue light comes on when I use the button or the remote it turns on and the olevia logo come up nice and bright then 2 sec later it gose away but the tv is still on. Now I have checked the volts out of both power boards and they are all good and I just got in a good used main board and still nothing. I did use a flash light to check to see if I see any video and yes I see video only with a flash light. This tv has 6 lcd inverter boards and all look great. I have checked all caps and all that I can see look good no bulging tops. Now I have read a thousand posts saying the t-con board turns the backlights on and it may be the problem then I read posts that say it's not the problem please help thanks Dan

I have just read so much conflicting fixes. I have a used t-con board on its way but was hoping some one could shed sum light on this

Re: Please help I'm loosing my mind 65" tv

I doubt if there's anything wrong with your tcon because you say you have a picture.

You appear to have an inverter fault but it needs to be diagnosed to confirm.

Also it would help to post pictures of your boards and interconnections of the boards and take the voltage readings so that forum users have some idea of what is going on.

If you do a search at the top of the page for "Olevia 265FHD" you should find the page I was refering to.

Ok I just pulled the inverter boards and the one in The middle on the left hand side has a darker Brown spot on the back all the other boards seem to have a little bit dark spot near each in inverter that looks like it was there either from heat or from them slaughtering it but the other Mark is in the middle of the board near one of the circuits

Could it just be that one board that's giving me a problem

You can see the dark brown spot on the right-hand side of the board like I said I would think that under the inverters it would be a little darker and seeing how they do get hot but in the middle of the board is just a small chip. Thanks for your help

Yes, if one transformer is faulty then it would cause the problem.

If you have a meter you can measure the resistance between the pins and compare to the transformers alongside. Meter set to ohms.

Edit
Is that dark spot under the transformer or under an IC. A picture of the topside would be useful.

Could it just be that one board none of the others have that same brown spot

Re: Please help I'm loosing my mind 65" tv

and thank you so much for the fast reply I'm going to go try to measure the resistance right now

[Danvagos]

Re: Please help I'm loosing my mind 65" tv

Also where would I measure the resistance I saw a couple of videos but these inverters do not look like the ones that were online

The heat mark appears to be under C5103. Can you check it using your meter in diode mode.

Edit
Check your fuses CP1, CP2 & CP3

This is the top side of it and you can even see the little bit of brown on the top of the board how would I test to see if it's bad

[dick_barton]

Re: Please help I'm loosing my mind 65" tv

It does look like Q3 has got really hot. You should be able to compare readings using the readings from a second board.

Re: Please help I'm loosing my mind 65" tv

If I tested here and on the other post the reading seem to be the same on all the boards In diod mode
