*What were the events that lead up to the receiver not working and the lights blinking?

*Was there/Do you have any power issues? Generator or mains around the time issue happened.

*Has the receiver been opened prior to it not working? If yes, what was done?

*Was there any software updates uploaded onto the receiver a day or two prior to it not working?

Answer these questions and i'd get back to you with a possible solution to your problem.

@Swordswifter
Thanks for your reply. I am sure that none of these events happened. It was working alright just before. Turned off for a while (may be 2-3 hours) and then turned on back again and there was no sign of working, only blue light was flashing, thats it. I opened afterwards and there is no visible signs of any capacitor leakage/any burn out signs etc. Never had any problem before. Was working perfectly alright. May be powersupply board may have something wrong.

INSTALLING A 12v FAN ON THE PCB OF AN SRT 4910 HD DECODER
This is just to help improve the cooling system of the receiver and to help you increase the longevity of the components. It will in no way guarantee the freezing and or unnecessary rebooting of the receiver when the leaking current accumulates back onto the circuit board. Use the method i posted in my earlier post to solve that problem. The things you'll require are;
* Soldering iron
* Soldering Lead(quality type for neat soldering)
* cleaning brush(for elctronics)
* PVC sellotape
* Screw driver
* 12v cooling Fan(Got a specialized fin type on a microprocessor of a PC graphics card)
* 2 pieces of wire strips
* Some white glue

Disassembling the srt 4910 HD receiver
The are 5 screws holding the outer casing together. A screw at each side of the box and three more at the rear end of the receiver. First unscrew this and take the cover off. Now unscrew the two screws holding the front panel of the receiver and gently but carefully remove the power connector, the front panel connector and the cam/card reader module connectors. Then remove the front panel usb connector and slide the front panel forward to release it from the lower case. *Remember what you take from where and keep the set of screws you remove from each slot together. Now turn the back of the receiver. You have five screws here. Unscrew all the five screws and keep them safe. Two of these screws are threaded differently. One is on the digital optical out interface and the other is inbetween the RF-In and RF-Out connectors. Be careful you don't mix these two screws. When screwing them back and you face a bit of a challenge, stop and check the threading of these two screws so that you don't damage their slots. Still at the rear, there are four more auxiliary screws you need to take of the receiver. Two of these screws are like knots on a bolt and are placed on the LNB input and the Loopout connectors at the back of the receiver. Unscrew these two and take off their washers too. Now unscrew the other two screws that hold the RS 232 connector at the back of the receiver. Now move on to the main PCB and unscrew the four screws left on the board. There are also two tiny screws that holds the cam module in place on the lower casing of the receiver. Use the appropriate screw driver (a small headed star screw driver) to get these screws out and now you can easily take of the PCB to start your installation.

Preparation
Make sure you twist the edges of the two pairs of wires and apply a small amount of lead on the edges. You do this so you don't apply unnecessary amounts of Lead on the PCB in the cause of your installation. After this, clean the tip of your soldering iron and attach the two pieces of wire to the terminal at the base of the socket of your fan connector. It is important you get a fan with it's own socket. This will enable you easily replace it in the future when it becomes weak or gets damaged.

Installation



The area circled in the first image is where the power connector is connected. If you look closely you will see the power values written besides each terminal. Turn over the PCB and shift the board so that the bottom terminals are now placed at the top left-hand side of the board as indicated in the second image.



We are looking for a 12v power source so look for the terminal that is indicated GND and another that is indicated 12v and where they appear at the base of the PCB. Note these points and heat up your soldering iron. (For my board counting from the right of the lower pins at the base of the PCB, GND falls on the 6th terminal whiles 12v falls on the 8th terminal). There are different versions of this receiver (Australia, Middle-east and Africa). I haven't seen those boards yet though i hope they are the same so always confirm where your GND and 12v terminals are before you start any soldering. Do not apply extra lead if possible. Just heat the one on your wires and the base terminals till they bond together. Clean the tip of your soldering iron and do the same for the other terminals. Now turn over the PCB and connect the power connectors, the front panel connector and the connectors for the cam/card reader on the mother board. Make absolutely sure you haven't soldered any too terminals together or any loose hot lead has fallen anywhere on the motherboard. If you are sweating too make sure non of the sweat has fallen on the PCB. Now connect your fan into it's socket and conduct your initial test.



Switch on the mains from behind the receive and check the direction of flow from the fan. It is advisable the air blows out of the PCB rather than into the PCB. If that is not the case, you can swap the wires for the GND and the 12v at the base to reverse the polarity and change the flow of the rotation of the blades of the fan.

After that is done, turn off the receiver from behind, remove the fan connector and layout the wire at the PCB as shown in the fourth image.



Fasten the wires in place with pieces of PVC sellotape and fit the fan socket connector close to the edge of the PCB with some white glue. Connect the sockets for the fans and apply a medium but generous portion of the white glue on the bottom of the fan and place it on the cooling fins on top of the CPU of the SRT 4910 HD.







You are now done with the installation.

You can now start fixing everything back in the reverse manner in which you took it out.

NB: If you don't want the messy method of fixing the leaking voltage on the SRT 4910 HD as i had posted some days earlier, you can fold up some PVC sellotape on the screw holes on which the PCB rests and fasten your screws through it. This should most definately serve the same purpose of insulating the outer casings. the only draw back is that you'll have to take the decoder apart to get there.

@swordswifter
I like your post about installing external hard drive and this one. I have SRT4910 since 2009, it stopped working and only front flash light near power switch button is blinking. It is australian version of box. Can you please guide me how this can be fixed. I love this box, for the time being I am using an old Humax box, which has no MPEG 4 compatibility. Thanks in advance.
