Re: Sony XBR-70850B Lightning
My assumption right now is that its the EOL's that took a little sizzle. The loop is reporting varying resistances. Sometimes its good other times its in trouble. Quite annoying. I had to disconnect it in the meantime until I get out there and replace the EOL resistor.Comment

Re: Sony XBR-70850B Lightning
Wow! A tcon board under $20 for a 70" 4K Sony tv. That's a pretty good deal! I would be very surprised if that lightning strike passed through the main board and damaged only the tcon.Comment

Re: Sony XBR-70850B Lightning
TV parts has it for $17.
I replaced the main but it isn't working because of the firmware.
One guy I talked to says those cables and tcon go bad all the time from lightning?
BTW I do have surge on the entire house. It doesn't matter.Comment

Re: Sony XBR-70850B Lightning
Thats why I take the pain to unplug about 5 or 6 power strips every time it storms.Comment

Re: Sony XBR-70850B Lightning
hey op....not sure if you got it worked out or not yet. usb 2 is recommended by sony for sw update. also, unzipped file must be on the root of the fat32 usb. best thing ive found is to plug in the usb first, then apply power. it takes up to 2 mins for the flash to start, but you should hear the sound playing at that time as well as the grn/amber flash turns tu pulsing white light. when this happens, wait for 30 mins. if it doesnt start ( hear the sounds playing) afte 2 mins, you can rename the unzipped file to update.pkg (ill have to get the actual rename if needed). same thing though.....usb 2, on root of usb, wait up to 2 minsComment

Re: Sony XBR-70850B Lightning
1.Rename the USB file name from “sony_dtv********.pkg” to “upgrade_loader.pkg”
2.TV is unplugged
3.Insert USB software “upgrade_loader.pkg”
4.Plug in TV AC
-USB flashing, downloading software to TV (30 min)
If Amber/Green flashing on TV
5. Unplug AC and Plug in AC
-USB flashing, downloading software to TV (30 min)
-USB not flashing, Unplug AC and Plug in AC again
not sure if this will work in this instance, but ive had several units go between the two variants. good luck.Last edited by jostewcrew; 06-23-2020, 04:56 PM.Comment

Re: Sony XBR-70850B Lightning
Great! Im waiting for the new Tcon. Since I don't get a test pattern I have to assume its dead so I will try once it is here.
Thanks SO muchComment

Re: Sony XBR-70850B Lightning
Hey guys - got the new tcon. The tv is now flashing blue.
I see white backlighting but no image on the tv at all.
Very disappointed

Re: Sony XBR-70850B Lightning
Was the replacement mainboard new/used? If used, possibly defective? Have you gotten the firmware update to load?Comment

Re: Sony XBR-70850B Lightning
I really don't know about the firmware. I tried renaming the file and letting it run last night and let it sit for hours to no noticeable improvement.
I am stuck. The more parts I add the worse it seems.
I am going to test power today I think that HAD to take a hit and its the only board I haven't replaced at this point
The directions I read said if I disconnect the main board from the TCON I should get a test pattern and I still didn't get that with my tcon or the new tcon so its getting worse not better....

Re: Sony XBR-70850B Lightning
I just ordered three new boards (power, main and tcon). My wife and I are done with out bedroom being a workshop. Hopefully none of those parts are duds.Comment

Re: Sony XBR-70850B Lightning
Well guys, three new boards and it still doesn't work. Im baffled. Book says I Should see test pattern but hasn't happened now with three different tcon boards. I get absolutely nothing with this newest mainboard - not even the USB lights up but the digital audio out does light up. Power won't come on and no display. So I might have a WORSE mainboard... Guys I'm about to pitch this thing in the trash- Seems wasteful but I have now tried two mainboards, three tconns and one power board. This power board scares the crap out of me as it clicks at odd times even after being unplugged...Comment

Good Day.
I just replaced tcon on my sony kdl 65xg9505 and getting green amber leds blinking. all voltages are ok according to working sequence.
i downloaded firmware from sony and there is no .pkg fike.. after extracting it gives another file which contains multiple files like inf, payload.bin and 3, 4 other files. i just did that usb but did not worked. anyone knows anything how to do it..?
green amber blinking stops after while and then starts again. tv responds to remote control on off etc. before installing new tcon backlite was coming on without backlite... -
I have a Dick Smith 37" LCD TV, Model GE6804. I am using it as PC extended monitor only.
Problem is while watching tv, I hear a semi loud click(like a electrical breaker tripping due to overload, just sound like it but no actual electrical overload), then screen is covered with green or pink. I can still see the original picture image but overlayed by green or pink. See attached images. Pink.jpg is what I see, and Normal.jpg is before green or pink screen, What I captured was pink screen, but about 80% of time it's green and 20% of time it's pink.
Then each time... -
I have a Sony KDL-55EX500 which shows a solid green screen and I haven't been able to diagnose the problem. I was able to find a repair manual online and read a few forums on tv repair which pointed me towards it possibly being an issue with the power board or T-con board. Bad electrolytic capacitors seemed to be a common theme so I tried replacing all of the ones on on the power board, but that didn't fix it.
My next step was disconnecting all of the cables and reconnecting them. That helped a bit, showing a normal screen most of the time, but still switches back to solid green... -
hi everyone,
my parents in law have seen their Bravia Sony LED 32EX600 TV set stop after a lightning strike. After being plugged to mains, it shows nothing no power LED on bottom left shines.
On the power PCB (GE3b, attached pic), I chacked the fuses and the only roasted one is R6536 : 0.47 ohms, 1/2W. After replacing it, I made some voltage measurement with ref to the chassis :
- the 450V/150uF capacitor voltage when plugged is normal at 394V
- from connector CN6150 (15 poles)
STBY normal 3.3V -> I shunted it to 3 (POWER ON) and 11 (BL ON) and unplugged...06-28-2023, 02:43 AM -
