    DVB Tuner

    Hello,

    I have a question about a DVB-C tuner who suddenly stop receive channels.
    Working very well but now I can't found any channels when I scan all frequencies.
    It's not a problem with signal or cable because an another tuner work perfectly.

    Do you know what components I should check and if it's repairable ?
    I found really few documentations about that issue and all people change the tuner without try to repair

    Philips SAA7146
    Demodulator : TDA10023
    Tuner : CU1216L


    Thank you for your help

      follow the tracks between the input connector and the chips.
      there is usually a transistor that can get spiked by static or just fail.

              Samsung PN51F8500AFXZA broke off the tuner's F connector, can't get tuner de-soldered
              by DXseekerMO
              I can hear Fred Sanford now...."YOU BIG DUMMY".....I pulled the "F" connector out of the tuner by accident. The tuner number is BN40-00248B. Low and behold I had a scrap board with tuner number BN40-00248A. Although the tuner is different (according to Encompass.com) it's footprint on the board is exactly the same as the 248B so I decided to de-solder the tuner off the scrap board to see what I was getting in to.

              As you can see in the picture the terminals and solder pads are super small. No matter what I tried I could not get either the terminals or support...

              Harmon Kardon AVR340 no sound on 4 channels
              by r2digital
              Hello, i had this amp sitting in the closet knowing that none of the channels were working. After taking it all apart i found 4 bulging main filter caps so i went ahead and replaced those with low ESR kmet caps. However after doing this it only restored sound to Surround L, Surround R, and Center channel. The main speaker fuse on the transformer F905/F906 keeps blowing so i decided to remove all of the transistor's on those 4 channels and measure them. All transistors appear to be in good working order(turned receiver on with none of them installed and fuse still blows). Checked dual emitter resistors...

              Advice needed-Technika 32-207 works but sticks on channel,won’t change channels ok
              by rustinjust
              My tv will work for a while and change channels with the remote as it should but then it will stick on one channel only and work ok but it won't change channels. I have tried unplugging it for hours and whilst unplugged pressing the power button on the tv to reset it.

              The volume button on the remote still works but it just won't change channels once it decides to stick on one channel

              It has built in basic freeview tv here in the uk, I've tried doing an automatic search to reset the tv but nothing works.

              I have to turn the tv off and then on again with...

              Does Changing Out Caps In A Tuner Effect FM Reception
              by Mark R
              "TQ" Subject at hand is a Marantz 120 tuner. The tuner lit up but no output. Recapped the entire unit. Before it was working fine tuning in Stereo and Mono. Now it just about tunes Stereo and some of the mono stations are weak. Nothing else was changed. When you do hit a stereo station the stereo lamp will come on but flickers as it's trying to hold the MPX signal.

              I don't see how bringing the unit back with new caps checked by my Sencore LC103 would effect the FM section. Every Value is as it was from the factory?

              Any Thoughts?

              Samsung 225MW EEPROM bootloop
              by Jacksoft
              Hi all,
              I got an old Samsung 225MW TV with BN41-00825 motherboard.
              Since the TV has a buzzer when it starts it makes a beep. The main problem is that the TV goes in a sort of bootloop and beeps every 2-3 seconds.
              So I attached the VGA UART cable and read the debug data using a RT809H programmer:


              According to the Service Manual all the voltages looks good, so I made a backup of the internal flash and all the EEPROMs (1 Settings + 3 EDID) and cleaned the EEPROM.
              Now the TV boots but it's stuck on VGA. If I try to change the source it goes to TV, restarts...
