    Philips 21PT5006/79

    Hi, folks.
    I tried to get the schematic diagram for this set at various places but to no avail.
    I was wondering if you did know where to get it.
    Have this dead set, with power supply working and voltage at the collector of horizontal output transistor, but no pilot light on.
    I did check for faulty diodes and the like but nothing - I need the diagram to trace the fault.
    Could you kindly help, thanks.

              Check for voltage on the Horizontal Oscillator transformer which would be connected to the Collector of the Horizontal Oscillator Transistor which in turn will switch on the Horizotal Output Transistor. Check for approximately 0.3V or 0.5V on the Base of the Horizontal Oscillator Transistor. If No Voltage at the Base then there is no Horiz Oscillation to trigger Horiz Out Trans.

                  Dynacord powermate 1600 block diagram.
                  by hs5424
                  Hi All,
                  I obtained a schematic diagram for the above mixer but I am wondering if a block diagram exists as I am trying to fix a problem in the protection circuit which I find a little confusing using a circuit diagram only. In the good old days the workshop manuals always had a block diagram with a circuit discription. Very useful for fault finding.
                  The protection light is perminently on. The right sode has a -80DC on the feed to the speaker, hence the protection led on. I have removed all the O/P transistors which checked out OK. I tested all other transistors in circuit which seem...

                  Repair attempt Philips 55OLED804/12
                  by Sharpa
                  Hello,

                  I bought a SH Philips 55OLED804/12 TV with known defect in an attempt to repair it for personal use.

                  The symptoms when bought: Philips logo appears then tv turns off

                  Things tried so far:

                  1. Powering it on: Philips logo shows on the screen, sometimes with some minor artefacts then shuts down. Red status led flickers rapidly into two batches then repeats
                  2. Put it in recovery mode by pressing joystick down then plugging it to mains: The tv shows the logo then shows the android animation along with some minor artefacts on the screen...

                  Asus ROG Strix G17 , Identifying a part number from the boardview diagram ID
                  by SilverbackITGuy
                  First of all, I hope I got this into the right section. Apologies if I did not.

                  I was working on my Asus ROG Strix G17 (2021) G713QM-RS96, and I guess I pre-heated the board too much replacing the DC Jack and one of the small parts came off. I looked for it on my soldering mat, and it was nowhere to be found. So now, the laptop is powered from the new DC Jack I installed, but it will not charge the battery from that jack. Only powers the hardware.

                  I looked at the boardview diagram in another post for the G713QM, and it looks like the diagram displays it as X450, a 4 contact...

                  Philips 8200 series 65PUS8204/12 stuck at Philips Logo
                  by G33RT
                  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 ?
