    Again 6 blinks on a TNPA5335

    I'm newbie here.. I have tx-p50gt30 tv, with 6 blinks... Measured >200V on C631, then changed the two DG302 (Q441 Q442) and their drivers IC502 and IC531. Then voltage across C631 dropped to zero (no on board green led on).. Then changed other two DGs and drivers IC522 and IC551..but nothing changes. All parts taken from a working SS board. Both 15V and 5V are there, and Vsus rises to 204V (that should be ok). Checked all diodes and resistor in the recovery section, all seems ok. After this, still 6 blinks!! Can you give me any help to solve this??
    Thank you so much in advance!

      Partially solved: changed IC16562 and no more six blinks...Now the board goes...

          Panasonic P58V11B 8 and 12 blinks error "fix"
          by Biruslapio
          Bought this TV used not working, panel flashed briefly on power up and it was blinking 8 times, a quick look on SS board revealed a common fault on the 3uF 250V capacitors, C201 to C205 (C1620X in the service manual), the solder joints were all cracked, C201 and C205 pins were darkened and some sparking had occurred on them, C201 was split open and clearly overheated in its last hours, replaced that one and resoldered the others, 8 blinks fixed.

          Also the previous owner broke the antenna connector by taking the TV out of the wall mount forgetting to unplug it, I desoldered the tuner...

          Samsung DM32D – Red LED blinks 5 times, won’t start (possible mainboard issue)
          by Nairolf
          Hello,

          I have a Samsung DM32D display.
          When I try to power it on, the red LED blinks 5 times and nothing happens—the unit won’t start.

          Here’s what I have tried so far:
          1. Disconnected the cable between the mainboard and the power supply → the backlight turns on.
          2. Disconnected the main T-CON ribbon cable → same issue as before, the LED still blinks 5 times.
          3. Disconnected one of the two T-CON ribbons to the panel (tested each one separately) → same issue, the LED blinks 5 times.

          From these tests, I suspect the problem might be on the mainboard. Could anyone...

          Tx-pr42gt30 6 blink
          by Userrrname
          👋🏻I recently got a tx-pr42gt30, I bought it in non-working condition. When I opened it, I saw that all the transistors and diodes had been removed from the tnpa5330, and several microcircuits were in poor condition, so I decided not to try to repair it. Instead, I bought another tnpa 5330 (also AB), which was already repaired (according to the seller, the board was repaired and worked before the screen was damaged), transistors were also changed on it, but Chinese copies were installed (there is no round hole in the middle, the inscription is easily erased) and a pair of transistors that...

          Panasonic TC-P55ST50 8 blinks then no blinks
          by Andre Gilbert
          Hello! yes I know there is already lots of information about this issue. I have a Panasonic TC-P55ST50 that originally displayed an 8-blink error code. Following the troubleshooting flowchart, I ended up replacing the SS board. However, even after replacing it, the issue persists. The TV turns on and stays on without displaying an image, and continuity is confirmed on all connectors. What am I missing here🤔?
          Ok Im a mechanical engineer ...but I thought I was able to follow a rather simple flowchart for electric troubleshooting 😂.

          Asus ROG Ally X -RC72LA - changed hidden bios settings with 'Smokeless-UMAF', won't get past boot logo
          by throwaway327
          ASUS ROG Ally X - (Handheld Gaming PC)
          Model No: RC72LA
          Serial No: SBNVKD001014459

          Hi all, I've spent the past week digging through the forums and guides to try correct my foolish mistake of changing hidden settings while tinkering around, and to be honest my heads overloaded so I'm hoping you'll be able to help.

          I used a tool called 'Smokeless-UMAF' to access usually hidden settings in the bios. I tweaked one or two 'safe' things but made the mistake of tweaking a lot of settings under 'USB/Thunderbolt Configurations' when I didn't know what they did. For...
