Re: Sony KDL-46HX850 clicks, no picture, standby LED blinks 3 times, repeatedly
Hi Budm,
Sorry been away a while, but came back and measured for DC voltage at the speakers. Found none! However, I was able to temporarily "borrow" a working BAPS board from a buddy's unit this past weekend, and with that, lo and behold, the unit came alive!
The backlight subsystem lit up, and both the sony logo and the sound system (white noise whoosh) kicked in for five seconds and then cut out, but the backlights remained on. In subsequent switch-ons, including...

Re: Sony KDL-46HX850 clicks, no picture, standby LED blinks 3 times, repeatedly
Are there more than one version of the BAPS board for the HX85x series? The board in this set has the black connector for the external speakers on the base/stand near the lower left corner of the triangular board. I've seen others on the internet (same model number etc) with a smaller white connector (like those for 4-wide audio cables) in that same location.Leave a comment:

Re: Sony KDL-46HX850 clicks, no picture, standby LED blinks 3 times, repeatedly
Had it open this weekend but had no camera. Here is a mobile phone picture with only the back removed, hope it is is clear enough. 4 boards are visible, five if I count the small Wi-Fi module, some under cover. The flat ribbon cable into the triangular BAPS board was very stubborn and for fear of breaking something, it was not touched. This stopped any further dis-assembly into the layer below what is shown in this picture. If there is a catch that releases the ribbon cable, I was unable to locate i...Leave a comment:

Re: Sony KDL-46HX850 clicks, no picture, standby LED blinks 3 times, repeatedly
Hi Budm,
Much appreciated. Schematics for these are indeed hard to find on the web or elsewhere. The only manual/diagram I've come across so far is the chassis/dis-assembly service manual. It has a wealth of relevant information, but alas no schematics.
I continue to search for these, may be one will turn up. On another note, the manual I have has a section on a "service mode" accessible from the standby mode using the remote. Will the faulty BAPS board allow this?...Leave a comment:

Re: Sony KDL-46HX850 clicks, no picture, standby LED blinks 3 times, repeatedly
Is this protection circuit defeatable somehow?
I've just missed out on a couple of BAPS boards that recently came up at ShopJimmy.com. I am back on the waiting list, but with no availability date indicated, I am tempted to try hacking the "faulty" board. Thinking of putting it on a test-bench, together with its PSU, which I really don't want to add to the casualty list, and running basic component-level tests.
Is there a component/part that is known to fail on...Leave a comment:

Re: Sony KDL-46HX850 clicks, no picture, standby LED blinks 3 times, repeatedly
Hi Budm, all,
is it normal for the Audio protection to disable the display portion of the set such that I am completely unable to perform the visual diagnostics suggested in these forums. I am not getting any backlight, or indeed any response from the set other than the click and the blinks.
All the same, I will study the schematics to see if there is a pointer in there to the problem. I am also sourcing a replacement BAPS board, hoping that it is the only part that was "hit"...Leave a comment:

Sony KDL-46HX850 clicks, no picture, standby LED blinks 3 times, repeatedly
Greetings from Nairobi, Kenya. The above referenced unit, now out of warranty, went off quietly while in use, after 4 years of regular use, and was thought to have been responding to a timer setting. Though local power is not clean/reliable, it was protected by a Teledyne power regulator and an APC anti-spike strip. Local SONY say they have no spares for it. As it is now it will click upon connection to power, and the standby LED will blink continuously in groups of three, and a minute or two after power is disconnected, after the LEDs have gone off, it will "double-click," no picture,... -
Re: EPoX 4PCA3I fixed
Hi trhisdone,
I have this very same board, very clean and nice looking, just like in the pic above, but also very dead. Started by suffering random resets, and ended up stuck, wailing a repetitive hi-lo banshee tone. I retired it befor capacitors exploded, but a good number are nicely fat and round, and dried up goo is visible is places.
Did you recap from an existing kit from this site, or did you make a custom selection? I am so encouraged by your success, and am already seeing the board back in action, complete with the SATA...Leave a comment:

Re: MSI MS-6337 815EPT Pro Ver5 recapped
I believe I have had this very same motherboard die out on me a year or so back, after about four yoears of solid service running Win2K, wait for it, Server in PDC mode.
I will go dig it up and confirm, I may just want to see if I can resurrect it similarly, just for the heck of it..., as it was, other than the capacitor goo tracks, in pristine condition when I so very reluctantly prised it out of the case...
