    Brimax T2030R 20" TV, standby LED on but can't turn on

    I've started fixing this second TV I got in a lot with the big 37" Samsung (I've opened another thread).

    It's a small 20" TV with an external 12V 4,16A power adapter. The back of the TV says 12V 5A. Also "made in EU".

    Here's what it does: standby LED turns on when the adapter is plugged, but when I turn it on, it flashes the tellow LED and goes back to red. The backlight and image on TV is flashing when this happens, but the image is very dim.

    I've checked voltage during this process by touching the TV PCB near the DC socket with my multimeter: 12V on standby, then after pressing power button it goes down to 5V, then to 11V, then back to 12V.

    It could be really simple. The TV doesn't look like it was messed with. The power brick could be incompatible? 4,16A rated on brick vs. 5A on back of TV.

    I need to fix this so I can get enough motivation for the big sister. Thanks in advance.

      Personally I would try to get hold of a 5A, 12V supply and check again. The power supply at 4.16A can supply 50 watts compared to 60 watts for the 5 Amp supply.
      Willing to help but I'm no expert.

          I bought a new 5A adapter and the TV works. At least I can sell it to cover up the initial cost of the two TVs. Thanks got your help!

                  Hi guys, I’m back here my friend give me her tv, that doesn’t turn on and no standby red led. When u plug in the cord the red led of one two second is on, then turn off. If you push the power button or the remote the red led blinks but nothing happen. I give u some photo with voltage, don’t look the fuse….because I blow it for mistake nd I dint have the right replace so I just put it for test the tv. The standby voltage should be 11,88 volt on the diode, but I have 13 volts. I put in the photo the different volts I test and there are someone negative…I don’t know if it s normal. On...

                  Harman Kardon AVR 171S - standby led lights up, does not turn on
                  by madsox
                  Greetings!

                  Thank you in advance for your understanding, I am writing to you through a translator.

                  A Harman Kardon AVR171S amplifier was given.

                  The history of the machine is as follows:
                  It was faulty when I bought it, I want to fix it.
                  I replaced the HDMI switch and one of the DAC ICs in it.
                  After that it worked without a problem.

                  I watched a movie using the amplifier, and at the end the amplifier got really hot.
                  The cooling was faulty, I will fix this later.
                  I switched it to standby mode, waited for...

                  Lenovo Y700-17ISK turn on and off
                  by pajdek
                  Hello, i have some issues with my laptop Lenovo Y700-17ISK (motherboard BY511 NM-A541), it started when i turn on the laptop, but the lcd wont turn on, i then connected it via hdmi to tv and screen was ok. So i thought maybe lcd stripe is faulty, i removed the bottom cover, disconnected main battery, reset the cmos by disconnecting battery for 1 min, then slighty move the lcd stripe. Conncted power supply and tuned on my laptop, the lcd turn on, it started to load os, then it turn off, after a second it turn on, then after like 3 seconds turn off again, and so on. Removed power supply, waited...

                  Samsung LN32B540 - won’t turn on but gets standby power
                  by Doodle43
                  My Samsung LN32B540 never turned back on after I had to turn off the power at the mains at house. It won't turn on, but the red standby led lights up when it is plugged in. If I hold down the power on the remote, the standby light turns off which I think means it is trying to turn on, but there's no sound or backlight. If I try to turn it on/off from the power button on the TV instead, it doesn't do anything at all.

                  It was plugged into a surge suppressor and was off (on standby) when I turned off the power,, so I don't know if it got a power surge or was on its way out anyway. I...

                  Troubleshooting Vestel TV, has standby, but cannot turn ON
                  by Adenitz
                  Hello,
                  I need advice in troubleshooting Telefunken TV (it is actually Vestel). There is red Standby light but TV cannot be turned on either by remote control (which is good and tested on another TV) or by actual on/off switch at the back of the TV.
                  Power board is Vestel 17IPS71 and I'm not sure about the mainboard, it seems like 17MB82S
                  Both boards are shown in the attached photos.

                  What is normally first that is checked in this case. I have removed power board, make sure it has no dangerous voltage on the big caps and check many components (transistors and diodes)...
