    coby tfdvd2695 power issues

    I just picked up this tv with known power issues. I figured it was a bad capacitor and would be an easy fix as I have done quite a few of them. Well, the capacitors look good.

    Here is what happens, when I plug it in the blue standby light lights up but when I hit the power button the screen comes on white then the tv shuts off along with the standby light. The standby light will come back on and do the same loop when I unplug the tv.

    I am kind of a novice in the electronics world so if i ask a dumb question please be kind to me. Ha ha

      Test the resistance of the secondaries of the inverter transfomers (while unplugged.) They should all measure within +/-3% of each other, except for one, if a failed transformer is responsible.
      Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

          1. Pictures help - a lot.

          2. A white screen sounds more like a main board or tcon issue than an inverter issue.

          For a number of reasons, both health and personal, I will no longer be active on this board. Any PMs asking for assistance will be ignored.

          Never be afraid to try something new. Remember, amateurs built the ark. Professionals built the Titanic.

              Here are a few pictures. Let me know if there is something else you want to see.

                      LG 55EG910V - no power and no standby light
                      by AleMonti
                      Hi everyone,
                      I'm trying to troubleshoot and repair this old LG OLED curved TV, model 55EG910V.
                      I did some basic troubleshooting and reviewed most related posts here, but I wasn't able to isolate the issue.

                      The TV shut itself off during playback and never came back to life - the standby light remains off. My dad claims that it has happened a few times in the past but the issue resolved itself after some time. Not this one.

                      After checking the basics I did the following:
                      • I measured all voltages and as expected the only active supply is the 3.5V standby. It
                      ...

                      Sony Bravia XBR-65x900f: No Power, No Standby-light - however 3.3v STBY is present
                      by SkishyIshy
                      Hey All,

                      I have a Sony 65x900f that I purchased cheap because of a no-power issue.
                      I assumed that because there is no standby light visible, it would be an easy fix - however upon opening up of the unit I can confirm that the 3v3 standby voltage is making it's way from the power supply to the main board. I'm a little confused as to why there is no standby light.

                      I am firstly wondering if anyone has this model of TV, or has worked on one and can give me some insight. I have tried to find a service manual for this model, to no avail - and would really appreciate...

                      Sony 55X900E no standby light, no power. Replaced mainboard already
                      by noinimod
                      No standby red light, nothing
                      This Sony has a separate AC->DC power adapter supplying 19.5V to the TV power board (JK3)



                      Disconnected JK3 power board from main board, checked voltages on all the pin outs

                      At a few pins I can see the power supply providing 19.5V to the main board



                      Based on the service manual triage.. it seems to be pointing towards the power board (JK3) being the most possible culprit


                      LED light turns on when I disconnect LED driver board ribbon from mainboard (so i thought it is the mainboard,...

                      Vizio E550i-A0 no power, no standby light
                      by x_orange90_x
                      I have a Vizio E550i-A0 that will not power on. It also does not display the standby light in the corner. I disconnected the main board cable to see if the backlights would light but they did not (maybe this is normal for this set?). I checked the voltages on the plug and they all read in mV or 0, so there's no voltage there. The fuses are ok, and the voltages of the 450v caps read about 160v. I see no visual damage on either the power supply or main board. I have read online that the main board is usually the culprit in this model, but not getting backlights with the main disconnected makes me...

                      LG 39ln540v - red light flashes twice, no power to LED driver?
                      by russpall
                      Hi there,

                      I've got a 39" LG 39LN540V that's just spontaneously stopped working! The symptoms are - when I plug it in, the red light will flash on twice, then go out, there's no visible picture, and I couldn't see anything using a torch on the panel either. If I press the power button (either remote or on TV), the red light comes on continuously. If I press power again, the red light flashes twice.

                      The TV is using a power board EAX64905301. I've attached a diagram of the power output, I've tested the voltages with a multimeter and I'm getting the following:
                      ...
                      Pin out and expected voltages
