Thanks. I am guessing then that the problem then (after googling for a good while), that it could then be a main Board problem, or tcon board problem?

I'm guessing the tcon board is under the center bottom screwed area between the power board and the main board.

Is there an order of process to work out my next plan of attack?

A number of threads I have read say to see if you can see the leads working or not by looking through any holes, but I see no holes to view them anyway. Some say to use a flashlight on the main front screen to see if you can determine movement.. or to turn volume up and listen if you get audio (I hear nothing), or to turn off the power at the wall, hold power on for 30 seconds via remote and see if anything happens.

Are these genuine checks, or backyard hacks?

Cheers

Am I at the end now, and it is disposal time for me?

Since the main board is not sending the T-con on signal to turn on the switched 12V for running T-CON board, thus you will not have any image on the screen.
Since Dimming control is also missing, the backlights will not be on either.
So something is telling the main board not to send those signals.
BTW, are you getting any error blinking code on the front panel of the TV?

No budm..

The TV emits nothing at all.. simply put, there is no indications of any sort at all.

It looks the same, whether the TV is actually connected to the power source, or not.

Not a sound, any light when pressing the remote or power button on the rear, or when supplying power at the wall outlet.

Is this your panel number T650QVF06..6 if not what is the whole panel number?

[viewerau]

Re: Remove rear panel Sony Bravia KD-65X7500F

Yes, that number was found on a sticker inside the TV, alo g with the other that read BMI 9009

The main sticker on the rear panel says KD-65X7500F

No guarantee but I would try a mainboard, looked but didn't see any on ebay AU, this one appears to be a match, looks to be a few available for about the same price, you can match up the numbers on the sticker to be sure or the panel numbers if available: https://www.ebay.com/itm/55-Sony-LCD...UAAOSwEGVeFQBz

Re: Remove rear panel Sony Bravia KD-65X7500F

Extensive list there, note many only ship to the U.S. : https://www.ebay.com/sch/i.html?_fro...acat=0&_sop=15

I think a 65 inch sony is definitely worth 75 bucks or so if a mainboard will fix it.

Re: Remove rear panel Sony Bravia KD-65X7500F

Thank you for the replies, we appreciate it.

Yes, if it is just that part, then it is really a no brainer I guess.

What do you think, with your knowledge, would be the chance that it could again be a further fault?

Would a technician simply do it this way, or would they undertake some other testing points before they took to simply try a new board, also punting that could be the problem. I guess most wouldn't have a spare board to test with?

Many thanks..

Re: Remove rear panel Sony Bravia KD-65X7500F

Thanks for the links.. Cheaper in Australia is about $125 plus postage. I will look on my board and see if my numbers match any of those numbers

[viewerau]

Re: Remove rear panel Sony Bravia KD-65X7500F

This is my board. I take it that if I use the links supplied, that I need a board that has all the matching numbers to my board, as I note that some look the same, but some of the digits differ.

many seem to be 1-982-454-11 whereas mine ends with the numbers 21

[nomoresonys]

Re: Remove rear panel Sony Bravia KD-65X7500F

I'm not exactly sure what the difference is in the last 2 numbers, something to do with what country/region? The way I matched up was by the panel number in my search, what are all the numbers on your sticker on the mainboard?

Re: Remove rear panel Sony Bravia KD-65X7500F

One thing that I notice is that the 11 has 5 rca jacks where as the 21 has 3 rca jacks.

Re: Remove rear panel Sony Bravia KD-65X7500F

Thanks.. The ones on nomoresonys link all seem to be one's with too many rca Jack's.. It seems odd to me when some mention they are for the 65x7500f...isn't it confusing..

Re: Remove rear panel Sony Bravia KD-65X7500F

There are many many very small fuses, I.E F402, 404, 405, 60x... on that main board, you may want to check them out.

Re: Remove rear panel Sony Bravia KD-65X7500F

Thanks budm.. Any other suggestions for us to check at the same time, so we can maxamise looking at many different things please?
Thanks

Re: Remove rear panel Sony Bravia KD-65X7500F

OK.. Check the fuses the next check, and if nothing found, a main Board would be a repairers next move?
