    Samsung PN51F8500AFXZA broke off the tuner's F connector, can't get tuner de-soldered

    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 tabs to de-solder from the board using a soldering iron, de-soldering pump or braid. The only way I was able to get the tuner off the board was to pop it in a toaster oven I use for re-flows, heat it for 10min and it popped right off.

    The Main Boards on the F8500 are scarce as hen's teeth and I don't want to mess it up when swapping the tuner out. Because of that I don't want to bake it in an oven. Are these intended to be removed with hot air? I don't think the tip on my soldering iron is too big for the job. It's about 1.5mm wide and the tip comes to a point. It appears I'm making enough contact for heat transfer to happen but they simply won't desolder.

    Does anyone have any ideas?

              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?

              desoldered capacitor is self charging until 0.6 voltage.
              by chth96
              I have an 21 inch CRT TV which is not able to power on.
              I disassembled 21 inch CRT TV and measured voltage of main filter capacitor(Samhwa HC 400WV 220uF) in the circuit.
              It shows 270V on my DMM.

              So I discharged this main filter capactior completely and detached circuit board from cathode-ray tube.
              Then I desoldered this main filter capacitor from circuit board.
              But I noticed that this desoldered large capacitor(Samhwa HC 400WV 220uF) is slowly charged by itself until it reached 0.6V

              I measured its ESR value with MESR-100 and it shows 0.1 ohm,judging...

              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...

              Broke off RTC Coin battery pin on HP EliteBook 840 G1 - Operating Systems do not load or install
              by nerdmafia
              Hi first question posting here, but no need to go easy on me!
              I have an HP EliteBook 840 G1 non touchscreen. The symptoms are that: Repairing or reinstalling windows freezes no matter how i try it. Live Ubuntu that works on any other computer also freezes while trying to load it. The RAM sticks and the harddrive work fine in other computers. I broke off the connector by accident, CN4750 and was using the laptop for a while with no coin battery. According to this schematic I found on here, which I THINK is the correct schematic, pins 2, 3, and 4 should short to ground, and they do....
