    Philips plasma FTP2.4A Vscan

    Hello guys,

    I got an old Philips plasma, I was hoping to revive this as i looove the ambient lights on the side,

    So it tries to start up, shuts down and blink on the front. The power supply gives a Vscan blinking errror, and goes into protection mode.

    When the Y board power supply plug is removed it starts fine, when the power plug is left in and the data flex cable removed it also starts fine.

    So where would the fault posibly lie? The power supply? The protection curcuit?
    The Y board? Or perhaps the mainboard is telling it to do somthing thats drawing too much current? Hmmm.....

      Oh also should mention, the unit is in unusually good condition, no leaking caps at all...anywhere. A bit dusty but other then then that almost perfect. And all voltages test out ok.

          I can't really help but what is the Vscan voltage and does it match what's given on the Plasma panel label?

                  Being as fast I can with the multimeter, it pulls about 265ma before shutting down, the power supply is only rated for 100ma. Hmmm..... Also the Y board has a fair bit of heat damage

                      Unplug the interconnections between boards and check the resistance of the various supply lines to ground. You may have a short circuit or a lower resistance than you should have on one of the supply lines.


                      Have you checked the Ybuffers for shorts. There are plenty of Youtube video's to guide you.

                      Post some clear pictures of your boards which can help.

                          Ok will soon, anyway there is progress found a stuffed capacitor on the y board, stopping the tranformer circuit from starting, so thats fixed......


                          NOW im getting the Vset error...ffs

                                  Maybe some pictures of the board would help
                                  I assume no responsibility for any stupid suggestions I might post.

                                      Issue with Plasma Philips 37inch chassis FTL2.1
                                      by celiabrown
                                      Hello guys,
                                      My Plasma Philips 37inch chassis FTL2.1 does no picture ,and goes into protection mode after 30 seconds (red led blinks at 3Hz).


                                      Can someone has any symptom like this ?

                                      Thanks​

                                      Hello, guys!

                                      The same 32" Philips TV I was having video issues, but now I don't have standby led at all. Someone here shared with me the schematic of the power supply, and checking the voltages, I see right after the resistor R604 I'm getting 1.6 v which is too low for enabling the Gate of the Q601 mosfet (the diagram says 4.2). On the R614 resistor I'm getting 181 V in and 117 V out, then through R603 I'm getting the same 117 V in and 59.9 V out, finally getting the latter voltage in the R604 BUT getting just 1.6 V out, which is the voltage that goes on to the Gate of the Q601...

                                      Samsung Plasma PN58B860Y2F low vscan

                                      We all of the sudden started getting a washed out picture and rainbow colored static/snow.

                                      When we tested vscan, etc., everything measured properly but not the vscan.

                                      Supposed to be -193 got -93 (tested it w the TV on)

                                      Researched it and decided to replace the y board and y buffers.

                                      Now I get no picture or sound - TV turns on but nothing else.

                                      When I run the same tests I am still getting -93 on the vscan test and this is now a different Y board, buffers, etc.

                                      So I am thinking either I did something wrong originally in...

                                      Philips 8200 series 65PUS8204/12 stuck at Philips Logo, it does not reboot it just stays on the logo.

                                      It does power up when pressing the power button.

                                      I already try the power button while plugin the plug with no result.
                                      Also put the latest firmware autorun-TPM191E_R.001.004.100.000.upg on a MBR/FAT32 USB stick at USB port2 with no result either.

                                      Could this be an PSU or eMMC issue ?

                                      Philips curling iron - is this a common AC cable?

                                      Hi all,

                                      Wife has 2 Philips hair curling irons half defective - after learning how they're supposed to work and testing them, it turned out that both have defective power cables, and both on the same place; broken wires due to wire bending.
                                      As they were both relatively easy to disassemble, and cables are plugged not soldered (as they can rotate in the handle), I was sure it would be easy to find replacements. But - NO! I'm unable to find anything similar on ebay or Aliexpress.

                                      Not sure if this is something Philips proprietary, or a standard, but the cable plug...
