ok, so are you saying that even without the tape in place that the tv works ok after warmup?

something to try, go into menu and try turning backlights very low, if no backlight adjustment try turning the brightness down, see if the double image changes any.

Yes, I have try everything that can be adjusted, and either set them to OFF or lowest level. No difference at all.

After 3-4 minute - the display will be perfect, regardless of the settings.

Ok, I bet it's similar to this 60X690E, if so it's tougher than most to get to those boards, being that you can't easily lay it down, might want to try all other troubleshooting before tackling that: https://www.youtube.com/watch?v=Zr42F0JYq38

It's much tougher than this...

could you show us the mainboards?

did you warm up the mb with hair dryer then turn on ?

Hmm - I have not but will do try this later.
MB attached.

Here the tech gets it down to one line covered but sometimes more need to be covered: https://www.youtube.com/watch?v=pfrRhw7-ZII

Although if you could get it down that far it would be easy to apply a little pressure around the tab bonds and see if the picture clears up, of course while testing all the boards need to be connected.

No benchtop space to lay flat the huge TV, so tried remove all the screws while standing the TV upright - can't seems to remove the cover plates to access the shielded the LCD driver boards...

Be careful, easy to break those screens.

Doesn't seem like there would be much difference, best way is to look up both datasheets and compare.

Checked and can't see any significant differences between SB5150 and SR5200
other than the voltages...
Also can't find SB5150 from the usual online shops, so will just get 4x SR5120 to try out.

maybe check the little mlc capacitors on the faulty side panel driver board for shorts or very low ohms.

SB5150 is Schottky Diode

I am not well verse with electronic components... Does it mean it must be replaced with this exact part number?

Re: Sony KD-65X7000E - Screen double images for first few minutes then back to normal

Just want to be sure this is not a potential root cause:
The shorted D751 was a SB5150 - a 5A 150v diode, and was replaced with a 6A 200v diode unknow brand from local hardware shop.

Would this caused the symptoms observed?

Yes tv unplugged from power.

Will do and report back later when it's setup properly.
*with power off presumably ?
