    Broken Philips LCD 42PFL3704D/F7

    So, I am a complete noob when it comes to repairs and I am trying to figure whats wrong with my TV and if it is worth fixing. This is the first time I have even looked inside a TV. I do have a manual but it is of no help, I probably need a schematic, but I have not located one yet. Here is what I do know so far:
    1. No picture (black screen)
    A. I have held a flashlight up to the screen and it is completely black
    2. No sound at all
    3. It does have power
    A. When I plug it in, I can here click (1 click I believe)
    B. Then when I hit the power button, I can hear it click on and I see the
    power led light up.
    4. Capacitors appear normal (no blown tops)

    Any help that can be provided would be greatly appreciated.

      Check this thread for some possible solutions:

      https://www.badcaps.net/forum/showth...ght=42PFL3704D

      If nothing there helps, there is another thread for this set that I found. Go to search and put in just the "42pfl3704d" and you will find the other one.

      Good luck

          Is it possible bridging tiny broken trace
          by chth96
          When I assembled dreamcast I mistakenly fastened long bolt and It resulted in
          cutting tiny trace.
          This tiny trace(Total width of white coating is 5.5mm) is between R337,R343 and IC101 and it is covered with white coating in the below screenshot.


          Firstly I tried to bridging tiny broken trace with my own eyes...But it is totally impossible..So a week ago, I ordered G1200 Digital Microscope and I magnified this tiny broken trace with it.

          But It seems that It is really very tiny trace So I plan to order 0.1mm coper wire from aliexpress in order to bridging...

          Philips 32PFL4901/F8 BA4GF0F0102 2 Not getting standby led
          by alro7779
          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...

          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 ?

          Philips 47PFS7509/12 LCD TV problem
          by janos6662000
          Hi

          I have here a Philips 47PFS7509/12 LCD TV which came to me with a weird problem : without signal i could access menu, make a factory reset, access menus, etc.
          When i applied cable signal to check image, i had normal picture, but TV was restarting.
          I downloaded original firmware and applied the update, but the problem remained.
          From a colleague i received a "factory package software" which is a lot bigger.
          I made another firmware update, but still did not solve the problem.
          Somewhere on the way the error got worse, because at the moment the...

          Aorus 17G YD laptop, broken display, could not switch to external monitor
          by ArchangelGabriel
          Hello guys! I need a little help, I have one laptop for repair, it is an Aorus 17G YD, gaming laptop. Broken display, some cable ripped form daughter board connector, case broken, battery discharged and probably locked, etc. After I did the most tedious job I ever did on soldering back the broken cables (shielded cable) , I measured resistance on CPU and GPU core, 3 and 5 v ps and any coils I find on the board, everything seems to be fine. After I plugged the charger I don't get the power led light on from the charger connection maybe because the battery is locked , but on power button I have
