    Philips 37PFL5522D Blink code?

    Picked this set up yesterday, it powers on after unplugging at the wall and plugging back in on a few occasions but most of the time it doesn't come on and the led blinks away


    After the blue turn on led it proceeds to turn red and blinks like this

    1 blink-off and wait-6 blink-off and wait 2 blink-off

    and it continues to do this until the tv may eventually turn on

    Have looked at caps, no obvious faults, startup caps at fault?

    Once it's been on for 10-15 minutes I can turn it off and on as much as I like and it works like normal

    Get the chassis code from the back for example LC5.9E-LA which will be useful in locating service manual. Philips TVs do use blink codes plus they also log them in the service menu so you might be able to see what the cause of it shutting off is.

      LC7.2E-LA

      so if i can get the tv back on access the service menu?

      ok got into the SAM menu

      error code appears

      6 2 13 0 0

      from the service manual, 6 being the last error,

      6: I2C error while communicating with the NVM

      2: 12v missing or low

      13: DVB HW Communication error

      12v, appeared to be fine when the set wouldn't power on


      trouble is once i've powered it on , it takes some time to replicate the symptomns again, i've cleared the error code in the mean time anyway to see what error i next get

        I'd focus on that 12v .... A good chance it's the cause of the other errors. Check connectors and cold joints. Maybe it's dropping out just before it powers on? Could also be a detection error.

          ok

          psu or main?

          seems caps would be a no as they all appear to be rubycon

          can't get it to replicate the problem again just yet

          but took readings anyway 12v is at 11.90v in standby and when on it rises to 12.30v

            seems you are correct tom

            12v is not there when the fault occurs

                Re: Philips 37PFL5522D Blink code?

                i've been reading into other 2 blink protection mode errors and some have solved it by replacing a resistor

                I can't find much from the service manual about tracing down the 12v fault

                any suggestions?

                  I'd try checking other rails, things like 5V main and 24V, aree they also missing?

                    i can't see any markings for a 24v the 5v appears to be there on both connectors

                    pictures of the boards if you can point them out to me unless i'm being blind

                      I removed the power board yesterday and never noticed this

                      On close inspection i can see a broken component it was still half hanging on the board but come off after i touched it

                      both are leading the 12v pins, this the problem i presume?



                      edit: I noticed a few times i'd hear a pop from the speakers when trying to power on it wasn't all the time but did happen and looking at the SCH now it appears those 12v lines are part of the audio

                      I just can't make out the part numbers from the SCH would anyone be able to help, i've attatched the portion of the diagram

                          That's a ceramic cap, is it shorted?

                              It could have caused your problem. My guess would be 100n ceramic. Value not critical, it is for high frequency noise suppression.

                                Panasonic ZT60 plasma tv with strange behavior and 8 blink code
                                by cloo
                                I recently got my hands on a 60" Panasonic P60ZT60 plasma tv (european model) that has some strange issues along with an 8 blink code.
                                It know this tv is getting old but it was once considered one of the best plasmas ever made, and i think it is still holds on to that even by todays standards.


                                So, long story short. When i first got the tv it had a very bright washed out picture with very raised blacks in all picture modes and i couldn't find the cause in the picture setting menus.
                                After doing a factory reset this problem was gone and the picture was back to...

                                Philips TV 43pus7505 setting display option code, help please.
                                by eurgenca
                                Hello.
                                I am dealing with a Philips TV, 43pus7505 and is stuck on boot loop.
                                So I ordered a used CPU board, and now I have wired picture.
                                I think the problem lies in display option code. According to SM, the command for setting
                                display code is 062598 + MENU + 032 (032 is written on a label on back of a TV).
                                But as soon I press the menu button TV jumps in menu. Can someone please tell me what I am doing wrong,
                                or can I manually edit option code in SAM.​

                                Panasonic Plasma repair - TH-P60GT50 - Dead, 3 blink code
                                by rmacintosh
                                I aquired this Panasonic 60" plasma around the time my first child was born. It was meant to be a project tv, hoping to fix it chipping away at the repair in my free time. Well that was 2 years ago and i'm really just getting around to making a sincere effort to see if I can ressurect this beast.



                                The symptoms of the tv ar as follows:
                                • Plug AC in to back of TV
                                • After about 2 seconds the relay on the P-sub board will click on and then a fraction of a second later it clicks back off
                                • The 3 blink code is given by the power LED
                                • If the TV is unplugged and then
                                ...

                                by djordje
                                Hello all,

                                I have Philips Oled 55 (804/12) with black screen and red light blink.

                                I have opened TV and tested voltages based on similar oled topics, on power supply board i am getting ps_o/f 3.3v and 5v for t-con_o/f while panel_o/f is 0v. And i get black screen.

                                Also i have done self psb test and i am getting on psb +12V_t and also + 24V for panel. (Measurements on dmm are + 12.3V fot t-con and 22.4 for panel)

                                When i power only psb and tcon with 4 ribbons for panel i only get black screen.

                                My questions is what should i do next...
