The power surge came-I think- through the DSL line. TV gave a very audible pop and died. (Ethernet ports in modem were all killed too). Power light on TV was dead. I ordered a "Complete LED TV Repair Parts Kit" from shopjimmy.com and installed everything ( https://www.shopjimmy.com/sony-xbr-5...air-parts-kit/ ). TV will turn on for about 30 seconds or so then shut down. Power light flashes 7 times repeatedly. I've seen that this indicates a high voltage shutdown.? But-where is this coming from since I've replaced power supply, main board, etc.? I see that shopjimmy has a IR Remote Sensor Board for this set (this is where the power switch lives). Could this be bad? I apologize for my ignorance , my electronic knowledge extends only about as far as swapping out parts.

Re: Sony XBR-55X800H Lightning damaged
I’m not sure about this model. But some TVs you can unplug the ir sensor and just turn on the tv from the joystick/ button on the tv. -

Re: Sony XBR-55X800H Lightning damaged
I can't upgrade the software because the set won't stay on long enough for that to happen.Comment

Re: Sony XBR-55X800H Lightning damaged
No joy )-: I got the set to start the upgrade a few times but it always shuts itself off again after 30 seconds or so after first powering on, then starts the 7 red flashes again. If anyone has any more suggestions please let me know.Comment

Re: Sony XBR-55X800H Lightning damaged
Thanks bskall, but I eventually wind up with "The described symptom may require further troubleshooting or a repair service. Please Contact the Product Support team for further support." I think it might be time to test shopjimmy's return policy and take this thing to the recycle bin.Comment

I recently found myself the proud owner of a later-model Samsung plasma (the PN59D7000 for those keeping score at home) whose panel was, unfortunately, damaged in transport. I'm now preparing to part it out, but am curious as to whether or not any damage would have come to any of the components by attempting to power it up with the panel being broken. I read in one Avsforum thread (for whatever that's worth 😂) that the "scan driver boards" (by which I assume he means buffer boards) could be impacted by doing so. Is that actually the case? If so, since I don't intend on selling bad... -
Hello everyone,
as indicated in the title i'm trying to identify the "right parts" to fix my sony 55xd9305.
the issue is already been identified in the motherboard since it seems that the main rom chip deteriorated and the tv can no longer boot (incredible in my opinion but that's it)
I can get full picture while booting from the usb to try "force" a firmware upgrade but the process stops after some minutes with a sony logo and a blank screen (it's on, i can see backlight).
So, i was searching for a replacement Motherboard (the memory chip swap... -
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 -
