    Cheapest/best cooling spray?

    A friend of mine describes his LCD TV as: "fully functional however when you first turn it on, a black "cloud" of some sort comes over the screen. Sometimes even half the screen is blacked out. After the TV has been on for a bit the TV works great and has no issues. Its only when the TV has been off for a bit and is powered on."

    This is an LT-37X688.

    So I found some freezing sprays that should help me find the
    problem:

    I would guess I should try spraying around the main input board first.....

      Depending where you are located. Here in the UK the best stuff on the market is Servisol and is found cheapest on eBay unless you have trade connections.

          Ordinary canned air serves two purposes. When upright due to evaporation it blows dust away, the spray comes out normally a bit cooler than room temperature. However, when inverted, the spray comes out very cold and frozen because evaporation doesn't happen. Around -180°C. However, canned air is pricey!

          The fault the OP suggests sounds a lot like T-con and it could be the LVDS connector is loose.

          Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!
          For service manual, schematic, boardview (board view), datasheet, cad - use our search.

              Samsung R530 Bremen motherboard cooling
              by Ace Perception
              Hi,
              I'm wondering if anybody out there has much knowledge of Samsung Bremen motherboards.
              I've got a Samsung R530 which is about 10 years old, over the last 12 months it developed a worsening problem where when asked to do much work it would shut itself down. I had a good idea this was due to overheating which was confirmed by a temperature monitor programme which showed little balls of fire next to the various internal temperature readings. I could also prevent it shutting down if I placed a huge fan running at full speed in front of its air intake!
              So I went in pursuit of...

              Liquid cooling?
              by Hondaman
              I hope my computer does not randomly reboot while typing this. My main system is the AsRock 970A-G/3.1 motherboard with the AMD 8150 chip. I am experiencing FREQUENT and RANDOM reboots once the system is used for a couple of hours (sometimes it reboots before I even get to the Win7/Linux Mint dual-boot screen). The problem MIGHT be the DRAM controller chip (I recently upgraded to the maximum 64 GB RAM). It also might be the VRM chips. I am using a typical aftermarket CPU cooler, which does NOT blow air DOWN onto the VRM heat sink.

              Help repair Panasonic fridge not cooling
              by mikey5791
              Hi all forum members,

              Few days ago, i might have forgotten to close my home fridge freezer door completely. The next day, the ice cubes and frozen meat almost melted halfway and the freezer doesn't feel cool. I shut it off, wipe dry and let it air dry for one whole day. The next day i switched on the fridge, the compressor run for a second and it shuts off(no vibration and no sound at all) only the internal freezer compartment fan is running but is not cooling even i switched on a full day.
              After shut off, i dismantle the rear water pan holder and reached to the compressor wiring....

              PC Power & Cooling Silencer 750W SLI only 0.10v on Green wire.
              by nubie
              I have an old PC Power & Cooling 750w EPS12V SLi power supply with the 80mm fan that is unresponsive except for the 5v Standby.

              Green wire has 0.10v on it. Will not start PSU when shorted to ground.

              There is an ICE2A0565 running the PSU and a
              HY510N 'watchdog'.

              Does anyone have schematics or an idea of where to start with this guy.


              5VSB is at 5.06v connected to Motherboard. There is a 7805 and a diode running the 5VSB it seems....
