    Technika LCD32-207/17pw15-9

    Hi

    Strange one, I got this tv and it has a bit of a strange fault, stripped it and found a butchered 15-9...someone has destroyed c901 & c801 and created there own poorly made tracks

    Anyway the fault is with the remote control, first thing in the morning or when the set is cold it will not start off the remote control but will start of the side buttons, once warmed up you can turn it on/off by the remote all day long.

    I thought it may be the remote sensor or main board so I fitted the PSU in another vestel and the fault was there on the other model.

    It looks like the psu has had the reliability kit and the joints all look ok, I checked r917-919and plopped another blob of solder on them all just in case.

    Anyone had this or have any ideas...do you think this has something to do with the Voltage Regulator??

    Thanks in advance

              Check voltage across 450V cap.

                      PFC IC failure, pretty common..

                          Is that IC807?? The 16 leg IC next to the Smoothing cap

                              No, it's the 8 pin SMD underneath.

                                  Got it IC802, right will replace that now, do you recommend replacing smoothing cap with a 450v 220 cap???

                                          I have got to show you this, I dont now if I should bother with this board....maybe this should go in the hall of shame, looks like they pulled the pads on c801 c901 and done a errrmmmm dont know if I can call it a repair, proably got the pidgeons to do it

                                          But thanks for your help Tom, just about to put the IC on so I will let you know how it goes.

                                              Hello all, I've been looking into this portable air conditioner's remote control and can't find what could be causing the problem - or possibly this remote is just terribly designed.

                                              The remote only works at exactly 3V - if I drop it any lower, using my bench power supply, to say, 2.9V then the remote will not flash the display and turn off. I don't have any AAA batteries that are exactly 1.5V each so I'm not sure if this remote is designed this way - to only use the freshest possible batteries, or if there's a failed component in the mix.

                                              I can't find any schematics...

                                              Hello everyone,

                                              I was wondering if anyone could help my in pairing a remote with a Toshiba fire tv?
                                              The Tv model number is: 50lf711u20 Rev B.


                                              I've already replaced all the the circuit boards within the tv along with the I.R. sensor receiver.

                                              I've tried 3 different remotes which should be fully compatible with this TV.


                                              Oddly enough. A few if the buttons on all of the remotes actually work. Even without pairing...which makes no sense.

                                              The power button, along with the volume,back,select, and directional...

                                              Hi! I have this TV set that does the following:
                                              1) I press the red power button on the remote
                                              2) The TV turns on normally
                                              3) After that it won't take any other command from the remote, neither power off, volume, channel, NOTHING
                                              4) We need to either pull the main cable or use the built in button at the bottom to select funcion OFF

                                              Then after it's off, it would again accept the TURN ON from the remote and same again

                                              BUT:
                                              -The remote does show the correct IR beam while observed thru a phone camera

                                              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...

                                              I’ve got a subwoofer that I’ve had for nearly 20 years, it did come with a basic remote which I’ve lost. It’s a generic make of subwoofer, I can’t see a brand sticker on it. It comes with 2 speakers.

                                              Question recently I’ve connected it up to my tv which has greatly improved the sound on my tv, however I’d like to be able to mute the subwoofer when ads come on or just mute it when the phone rings etc. I tried using a cheap all in one tv remote on the subwoofer and the volume button would only work to increase volume but not turn it down or mute it
