    Sony KDL-50EX645 6 blinks simple fix

    Not able to power on, 6 blinks.

    Tested the backlight OK with backlight tester. The problem is the 4 series resistors R602A-D values increased. Looks like everyone is possible to change values.

    I jumped the R602D (it's underneath the heatsink) with a wire (on the other side of the board) fixed the problem.

      Did you check the DCV on the main filter cap 82uF 450VDC after bypassing the resistor?

          Why not replace the 4 resistors if that was the problem?
          Willing to help but I'm no expert.

              There are different kits, but what are their names?
              6 flashes IC303, IC601 IC801 R602D
              6 flashes Q901 R602D
              6 flashes IC601 IC301 D305 ZD306

              IC801 is said to be NCP1608
              IC601 is said to be 2QS02G
              IC303?
              Q901?
              IC301?
              D305?
              ZD306?

                  Recapping Sony ICF-SW55 - verifying cap values
                  by proxneo
                  Dear reader

                  I am performing a repair on a Sony ICF-SW55, which includes recapping (some) of the SMD capacitors on the mainboard. I am looking for verification of their values. At the moment, I'm 95% sure I've got the right values, but it is hard to find some official, credible or multiple independant sources on this.

                  At the moment, I have selected replacements based on the following list of values:

                  3 x 470uF 10VDC
                  3 x 4.7uF 35VDC
                  4 x 47uF 50VDC
                  8 x 22uF 6.3 VDC
                  1 x 220uF 6.3VDC
                  5 x 100uF 6.3VDC

                  Which...

                  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...

                  Sony XBR-65X850D 2 Red Blinks
                  by Nicktronic
                  Hi all,

                  I have the subject TV and it will work normally sometimes but suddenly go black and give the 2 red blinks blink code. When this happens, I check the power supply board voltages and all I have is the Standby 3.3V and BL_ERR 2.2V. When it's working normally, all power supply board voltages look normal and stable. I've checked the backlights with a tester and they all test good. I've also read that the 2 red blinks is a faulty power supply board, so could it be throwing up an erroneous BL_ERR?

                  Any Sony experts out there that can help??...

                  Sony 75X9400E TV.. 5 Red blinks
                  by dumbdd
                  I was using this TV for 5 years before it stopped working. I like this TV and would love to fix it myself.*

                  When I press the power button, the white led comes on (sony calls the module smart core) and then it switches over to 5 red blinks. No screen, no backlight, no relay click, nothing. I have disassembled the tv and found the service manual for 75x940e online. The manual suggests a faulty power board, TCON or the panel.**

                  The standby pin is at 3.3V. Fuses on the mainboard and TCON are fine. Caps on TCON also seem to be fine. When I turn on the tv the white led...
