    Yes and it was bad as well. I'm trying to find suitable replacements but don't know what brand or series to use. From what I can tell, the package size is 0402. Its about a millimeter in length.

        My new digital caliper just came in the mail. The caps between pins 14, 15, which are same as ones missing, measured 1.04mm. So I think that would be the 0402 package.

            Those caps that are missing. Does the pin of the ic where they are missing from generate the error? Maybe they were deliberately removed by someone else trying to track down this problem
            Did I leave the soldering iron on?

                Looking at the data sheet for it, it looks like it might generate the error. It does have over and undervoltage protect circuits. I actually think its the BE Micro IC3001 that generates the error though.

                    Well, its back to the old drawing board. Those two caps and the fuses came today. Put them in but its still doing the same thing. LED still blinking 6 times. I does try to fire the inverter 3 times though. I'm wondering if its time to start looking at the inverter board.

                        Never going to believe this. The backlight problem is solved. There was a wire harness coming from the balancer which goes to CN6701on the power board. Someone worked on this before I got it. The harness was wedged up under the power board. So, now the backlights come on. New problem. The attached pic is what it does when first plugged in. If I turn it off then back on it is just a black screen. Once it went to a grey screen. Backlights are on though. Also, the pic/timer light and the standby light are both on.

                            Sony Bravia 55HX820 - 4 times blinking red standby led
                            by androripara
                            Hello everyone,
                            i am trying to repair a Sony KDL-55HX820 led TV which is throwing error code 4 (standby led flashing four times).

                            I followed the troubleshooting flowchart at page 69, and between pin1 and pin7 of CN6002 i am reading 1.91V so i guess i can rule out the B Board as the culprit.
                            Before ordering new G* Boards (by the way, should i change both? it is not specified in the manual) i wanted to try and do more advanced troubleshooting since i've read in other threads people resolving their problems on the 46/55 HX 820/823/825 models by replacing the Samsung led...

                            SONY BRAVIA XBR-55A8H - White horizontal lines / red LED flashes four times
                            by thstuff
                            This "free from a friend who was going to recycle it" SONY BRAVIA XBR-55A8H arrived with the bottom center RED LED repeating a four flash pattern. It was treated with kid gloves and was reported to have "just gone dead" and the OLED panel has no dents in the metal frame or cracks.

                            Thread https://www.badcaps.net/forum/showthread.php?p=1091829 helped in proceeding as follows:
                            1) Unplugged, then plugged set in while holding the remote VOL- and Power to factory reset.

                            2) Waited 30 seconds, then pressed remote Power button and "Select language"...

                            Sony KD-65A1 Repair – 4 Red Blinks Error
                            by AK_777
                            Hi everyone!
                            I have a Sony KD-65A1 TV with a fault – 4 red LED blinks. After disassembly and visual inspection, I found that the G76 power board and DKA board had been replaced. It is also possible that TCON was replaced, but I am not sure – there are a few marker marks that could be factory-made.

                            Based on assumptions, the previous service attempted to solve the issue by replacing potentially faulty components. I decided to investigate further, found a service manual, and figured out a way to power up the power supply unit autonomously and put the OLED panel and...

                            Sony A1e 5-blinks help
                            by jchon
                            Hi I'm new to trying to repair TVs, but I saw a broken OLED offered for a reasonable price and thought I'd try my hand at it.

                            I found the service manual, which was critical to know where to probe.
                            https://www.manualslib.com/manual/20...1e-Series.html

                            With it I was able to determine that my DKA board was bad, when P_ON#1/2 gets enabled REG_12 on the DKA board collapses. I'm assuming one of the downstream regulators has a short, but I couldn't work out which rail/component and replaced the DKA board entirely.

                            Unfortunately the 5-blinks...

                            from what i read online it looks to be an emmc issue…
                            i’m not familiar with this kind of tv repairs… i’m repairing laptops and gpu’s…
                            i took out the board and say an samsung 16gb emmc
                            i don’t have an exact replacement, but i have a few 32 and 64gb emms’s from laptops…
                            i could try to put one instead of the 16gb one, but will it work?
                            where do i get the software from?
                            any help will be much appreciated!...
