    Sony HiFi Tuner loosing saved stations

    Hi All,

    I have a 20+ year old Sony ST-S320 tuner that 'forgets' saved staions from memory. When I opened the case I was hoping to find a battery that could be replaced - but none was present.

    I've attached the service manual. Can anyone point to where I should be looking to fix this problem?

    Many thanks.

          Many thanks for the help.
          I've ordered a replacement and will report back when installed.

              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...

              Sony STR-DN1050 - No video, no BT, No WIFI, and FM is not changing stations
              by jason123
              Hello folks,
              New to Audio equipment - I got this receiver, I connected speakers and I tried to connect to Bluetooth. My phone would not see the receiver (Receiver flashes the BT as if it's trying to pair). Then I put it on FM radio, I get white noise on the speakers. I click the +/- Tuner button, and it moves from saved station 1 through 28, but the frequency is 87.x MHz not changing. At this point, thinking I may need to do a FW upgrade, I connected an HDMI cable to the TV and TV reports "No Signal" - TV "Kind of" sees the receiver (When connected to greyed out port,...

              55PFL4908K/12 DVB-S tuner not available
              by Ierwin
              Hello everyone,

              I have a rather strange problem with this Philips I just repaired.
              The set came with startup problems, I checked the PSU, found some puffed caps, replaced them and now it is starting perfectly.

              According to the philips website this tv should be equipped with a tripple tuner.
              However there is no option to scan for satellite channels in the menu.
              It only shows the option to search for DVB-T or DVB-C channels.
              The set is equiped with the F-type connector in the back so to me it looks like it is indeed equipped with a Sat tuner....

              Marantz Model 120 Tuner Craziness I am Stumped!
              by Mark R
              My Marantz 120 Tuner stopped receiving Stereo signals. It works fine other then Stereo. I have a fully loaded shop here with all test equipment except and RF signal Generator.

              I get great reception on FM so I have used that signal troubleshoot. I have been all over the MPX board and replaced all caps. Also the entire power supply caps were replaced.

              All Voltages on the MPX board are good... all Transistors Good...All Diodes Good and other components.

              The stereo lamp is good as I powered it up and it lights. The signal flow to that lamp is unbelievably...

              Sorry if I posted this in the wrong forum.
              As mentioned in the title I'm looking for Philips SAA7134 TV tuner card driver and software. Sadly I couldn't find anything online. Maybe someone here has them?
