    Finlux TV/DVD 22F6072-2 Will Not Work With Remote Control

    Hi,

    I have a Finlux TV/DVD 22" that will not work when using remote control. Have replaced the original remote control batteries, also purchased another Finlux remote but still unable to get the t.v working using remote?

    Apart from this problem, the t.v works fine but am stuck on what to check next?

    Thanks.

    check the little IR board on the TV. Maybe there is a shorted cap on the board, a bad regulator, or a bad IR receiver.

      Have checked the caps and resistors.

      R1-99.9R
      R2-56.1R
      C1-2.5uf
      C2-2.5uf
      C3-2.5uf
      C4-0.14uf
      C5-0.14uf
      C6-0.14uf.

      Not sure on how to check the IR1?

        IR1 has a GND pin an 5V input pin and a output pin. Check if the 5V or so are there and if that is o.k. hook up your DMM or better yet a oscilloscope to GND and the output pin. Take the remote and press a button. You should see pulses.

          Do not have oscilloscope so hooked up DVOM between ground (center pin) on IR and 5v output pin, pressed remote and voltage dropped to around 4.7V. Also did this test at the 5 pin connector (IR to AV Board) same result so seems as if the IR sensor is working o.k?

            When you test the IR sensor with a DMM, you should see a constant DC voltage. Once you press a button on the remote, the voltage should "jump around" a little bit. If it does, the IR is good and there is a problem on either the wiring or on the main board.

              More common issue is the firmware messes up and the Tv wont log the IR board when on. You need to re-flash the firmware onto the actual Spi flash Ic rather than Via Usb.

                if you have replaced batterys and have a phone with camera function,look at the IR sensor on the remote through the camera, if its working you will see it flash like a torch when pressing the buttons,also could be firmware/flash corruption on the mainboard

                  Tried the original remote with new batteries using the camera method, there was no flash so did the same test on the new remote and this time I saw a flash. So far I'm unable to find any firmware download for this main board (17MB82-2) also unable to find a replacement board, the closet I can find is for a 24" and 32" so not too sure if this would work on my 22" t.v?

                  There are a few boards for the 22" but they only have one HDMI socket?

                    Old Privileg 5.1 speakers remote control question
                    by piipo
                    Hi, I have an old Privileg brand 5.1 speakers. I have lost the remote control. I have an universal Harmony remote but there is no Privileg brand in it's software to add. Does anybody have an idea what alternative brand for a remote can I try instead? I'm attaching an image of what the speakers looks like. The image shows 2 main speakers, they are 5 + 1 in total. Thank you very much

                    Schematic for Denon Remote Control RC1156
                    by hemant_2222
                    Hello Everyone,

                    Hope everyone is enjoying their repairs at hand!.

                    I am looking forward to get the schematic of Denon remote control RC1156. Actually long time no use of the remote leaked the battery thereby corroding few parts as well as the tracks.

                    I was able to join few of them but the remote is still not working, so i am looking forward for your help, in case anyone understand the schematic or the remote circuit diagram and could me assist me in repairing it.

                    Please refer to the attached picture, i think the voltage divider is missing...

                    I managed to drop this recently. It fell flat and square onto the floor from about 1.8m. Can't remember if face up or face down.
                    The remote still kinda works but the display is blank and only shows up if I repeatedly flick the little silver crystal/oscillator looking thing on the board.

                    Not sure if this part is the culprit or if flicking it is moving something else, but it seems localised to that component as far as I can tell.

                    Having trouble working out the value of it since it doesn't seem to have anything other than a brand name printed on the side of it....

                    Opel Zafira remote control missing resistor
                    by LordJohn
                    Hello,

                    Can someone help me with either diagram for the IC on the attachment, diagram of remote control it self or the value of the missing resistor liked to pin 4 on the IC in the attachment.
                    I will restore the ripped traces, but the remote still be useless without this resistor.

                    Thanks in advance....

                    Pioneer VSX-522-K remote control not working???
                    by tmhobadcap
                    I have this receiver for at least 10 years. Usually, we just use the remote for turning on/off and adjusting the volume. Recently, the remote control started not able to turn the receiver on. Later, the volume also could not be adjusted by the remote control.

                    At first, I thought that it was the usual problem which can be fixed by cleaning the contacts on the switches and the pcb. I opened the remote and clean it with alcohol. The remote did work again after that. But after one day, it did not work again. I opened it again and clean with alcohol and contact cleaner. Again it worked...
