How to replace STK392-100?

I have a 61H70 and am trying to replace the two STK392-110's. After I opened the back cover, and removed the panel/board with all the video connnectors, there are several vertical boards with metal case on the bottom green PCB where the STK392-100's are. How do I remove these vertical boards with metal case?
Thanks a lot.

    One of the boards has a plastic socket like what you described. But I cannot see any socket for the other two boards as their metal cases go all the way down to meet the bottom PCB. I will take a careful look. Thanks so much.

Look at the very bottom of those boards they should have a plastic socket that they slide in. If they do you will notice a little plastic tab that has to be bent back for the panels to be removed from the socket.

I had the same problem with trying to remove the heatsinks (they were soldered and couldn't remove the screws) so i cut the connectors as much as I could and after removing the screws pulled vertically up on the STKs and rocked them back and forth until I was able to snap all of the connector legs. Using a soldering iron bottom side and a mini pilers topside I was able to heat and pull each leg out. Now to replacement of both and see if that solves the problem.

I am dealing with the same problem (Toshiba 61H71). I believe the vertical metal-cased board may be a tuner, and is firmly soldered (with many pins) to the PCB- blocking access to the screws that attach the STKs to their respective heartsinks) I am thinking the only way to remove the STKs is to remove the heatsinks as well (they are soldered on at only 4 points.

.... unless you found a better way :)

If the front side the oven has melted so that you are unable to do this.

Then the plastic cover would need to be removed, I beleave the buttons would still work without the plastic cover, but I do recommend geting this serviced by a professional but if you must get it to work right now.

I don't have a service manual so I dont know exactly how to remove the cover.

Advent t9307 power switch not working


Your laptop's power button sits directly on top of a device called a power button board. This is a small circuit board where all power and control buttons interface with your laptop's motherboard. The repetitive use of the power and control buttons can damage the power button board. Repairing your power button means removing and replacing the power button board, which requires partial disassembly of your laptop.

1.Power down your laptop. Unplug the AC power adapter and all external devices from the computer. Close the laptop's LCD panel and place the laptop face down. Rotate the laptop so the front opening edge is facing you. Remove the battery pack from its compartment on the laptop's bottom side.

2.Flip the laptop over, and pull open the display panel as far as possible. Use a thin, flat-head screwdriver to pry the keyboard cover from the laptop. The keyboard cover is the plastic piece situated above the keyboard assembly that houses the power button board.

3.Lift the keyboard cover out of the laptop slightly, and disconnect the cables extending from the power button board to the motherboard. Remove the keyboard cover from the laptop.

4.Place the keyboard cover face down on a flat surface. Remove the Phillips-head screws fastening the power button board to the cover, and remove it. If your speakers are situated inside the keyboard cover, disconnect the speaker cables from the power button board before removing it.

5.Place the new power button board inside the keyboard cover. Align the screw holes on the button board with the holes on the keyboard cover. Replace the Phillips-head screws fastening the button board to the keyboard cover. Reconnect the speaker cables to the button board, if necessary.

6.Reconnect the power button board's main cable to the motherboard. Place the keyboard cover back inside the slot above the keyboard assembly. Press down on the cover until it snaps into place. Replace the battery pack and reconnect all cables.

Close door, no lights come on, no sign of power. Circuit breaker fine. Door latches fine. ran fine day before.


There is a fuse on your main control board that comes off and can be replaced somewhat easily. Start by TURNING OFF THE POWER. Open the door down to the floor and take a torx(or starhead) screwdriver and remove every screw (10 of them usually) along the left hand side & right hand side of the inner door panel. Upon removing the screws on both sides it will free the outer door panel which can easily be removed by lifting the door back up to a closed position and pulling the top of the panel outward then lift up towards the ceiling and it should slide right off. Push the door back down to a fully open position (door back to the floor)and remove the 4 screws along the top which will free the control panel. Inside you will see a cover that covers the control board and has some arrows on it pointing to some pushtabs. You may be able to unlock these with your finger or get a screwdriver and just pry each one while pulling the cover up. Now you should see your main control board and your fuse, which is attached to the side of the control. It always helps to use your replacement fuse to compare it with. Before trying to yank the fuse off, gently pull the ribbon cable off from the left side of the board. Then go a little more to the left and you will see 2 more release tabs on the side of the board. Pry the tabs back and pull the whole control board upwards and it should pull up an out. With the board out it should be easy to identify the fuse clipped to the side. Use a flathead screwdriver to pry in between the plastic casing on the board and the fuse clip and slide the new one in its place. Always replace the fuse according to manufacter instructions, once removed improper install will lead to a premature failure of the fuse and you will get to do this all over again.

Red convergence will not line up on my jvc 56 inch i art projection tv model # AV-56WP74. PLEASE TELL ME WHERE CAN I BUY THE KIT SO I CAN FIX IT MYSELF!!!


You need to pull the front grill cover/panel off the front of the tv. Remove screws (4) from back that hold it on, also 2 small ones behind front video input door. Then remove access panel. The ckt board closest to you is the convergence amplifier board. You should replace both amplifiers (stk392-110 or 120) and any burnt/open resistors you find near the amps.(use the same value resistors as the corresponding resistors in the blue amp ckt)

RM2652 fridge works on 110 and gas but won't switch between them


Remove the upper control board panel. Use a small screw driver, open the freezer door, under the control panel you will see a slot on each side. Put the screw driver in the slot and push up. That side of the panel will pull out. Do the same on the other side. Turn the control panel over and unplug the circuit board and wait 15 seconds. Plug the board back in and give that a try. If that does not work replace the upper board. To order a board you will need Model, Serial and product # found on the inside of the fridge.
Thanks for using Fixya

Toshiba 43H70


The Toshiba 43H70 has two RGB driver chips (p/n: STK392-110) responsible for aligning the RGB colors, one of them went bad. Instead of throwing the TV away, I decided to try and replace them, and fix the TV. I did, and it works great! I ordered two STK392-110?s online from Electronix.com, it cost about $18 including shipping. Each STK392-110 is about 2? in length, and 1.5? in height, and is an 18 pin device. The tools I used were all purchased at Radio Shack, and are: a soldering iron with a stand, solder, de-soldering tool, thermal grease, and a digital camera (yes, a digital camera). First, make sure the TV is unplugged! On the back of the TV, take the back wooden cover off. You?ll see a bunch of wires going everywhere, a power PCB board (probably brown), and a green PCB system board. The two STK392-110?s are on the green PCB system board attached to two big heatsinks. You will have to remove the green PCB system board to get to the two STK392-110?s and replace them, there?s no way around it. To remove the system board, you?ll have to remove the board with all the video jacks on it, and will have to disconnect all the wires going to the system board, as well as disconnect the power board from the system board. The power board and system board lie right next to each other, and are connected by two connectors. You have to be careful with those two connectors, and I used a small screwdriver, got it between the mating connector, and gently pried it open. It?s like an old mechanical switch, but instead of one contact, there are several. While taking everything apart, this is wear the digital camera comes in, take a picture of everything you disconnect and remove, and play the pictures backward so you know how and where to put everything back together. The system board is held down by several screws that will need to be removed. Once the system board is removed, you can see the two STK392-110 driver chips, however, you will have to remove several vertical boards and heatsinks to get to them freely. The STK392-110?s are attached to two heatsinks by two screws each. The heatsinks are soldered on the system board, so you?ll have to desolder them to remove them. Once you have them removed, Now that the old STK392-110?s are freely accessible, go ahead and use a pair of wire cutters, and cut them off at the leads (the 18 pins). Now desolder the 36 pins left in the board. Use the desoldering tool to get as much solder out of each hole so you can easily put the new STK392-110?s back in. (Make sure you put them in the same way as the old ones!) Put the two STK392-110?s into the holes, put the thermal grease on the metal side of the STK392-110, then attach the heatsinks to them, line up the two mounting screws that hold the STK392-110 to the heatsink, and start soldering everything back together. Make sure you use enough thermal grease between the heatsinks and the STK392-110?s, too much is better than not enough. It will look like the 18 pins are all connected together on the PCB system board, but they are not, make sure you individually solder each of them to the PCB board, and do not let solder from one pin touch solder from the pin next to it!! Use the digital pictures you took and play them backwards so you can put your TV back together correctly. Attach your TV cable to the TV, plug it in, and use the remote to turn it on (stand back just in case you crossed some wires), it should work, and the picture should be perfect.
