Blinking screen on Sony SDM-HS73 17

So, lately my monitor has been blinking uncontrollably. The problem started about 6 months ago, and about after 10 minutes of blinking the monitor would finally work. Now, over the past week it continues to blink and I am unable to use my computer. I took the back cover off to look at the board, and it appears a few of the capacitors may have burnt out. C1, C23, and C25 appear burnt (black, brown in color) and the rest are all blue. I'm assuming this is the problem? If so, are they easily replaced? Where can I find them? I'd prefer not to order them online, I'd rather find them at a local store if possible. If I do replace them, is it as easy as pulling the bad ones out and sticking the new ones in? Or is there something special that needs to be done. Thoughts and/or suggestions would be appreciated. Thanks in advance....

    I said they were burnt capacitors, that may not be the exact term for them. I did a quick search on Google and it said something about capacitors, so that's what I called them. Either way, they definitely are located at C1, C23, and C25.

Not the board, there is a thermal fuse under the lamp housing that has opened up, you need to order an upgrade thermal fuse link that will mount to the Lightengine side of the lamp housing, the clips are there, there is no sensor there.

This is a simple and common problem. The solder joints on the vertical output IC have cracked loose. I actually did a housecall on the exact same set with the exact same symptoms this morning! A good tech will resolder the pins of the vertical output IC and all other major solder joints on the main board and the set will play fine.

When a Sony does what you explain it usually only needs it's screen controls adjusted. This would be the first thing before replacing parts or any other trouble shooting, To do this you have to remove the speaker grill, there usually are two screws down low that are covered by plastic covers, once these are out the bottom pulls forward and slightly down. Then there will be another cover, remove that. Now you should see the inside of the TV. Near the front there will be a control ruffly the size of a pack of cigarettes and have six controls on it, Three are for focus and three for screens, Next find a video source that has no input, this simply means change to a input that has no signal, and gives you a black screen. Next simply turn the screens clockwise till a faint glow and retrace lines appear, then turn it back down till the color just disappears. Do this to all three, then you can re-glue them with fingernail polish if you want to.
Thats the simple way to set the levels on the CRT's, Sony's have a circuit that mutes the video until all the voltages are within a certain range, if the voltages are too far off it will give you the five blink error code, now if does not fix the problem there are other problems, This can be any thing from a weak CRT to a capacitor failing. And on a final note it is best to let the set run for at least 20 minute before doing this adjustment to let the voltages stabilize, and it is best to check it after another twenty minute to make sure it stayed

Its possible that one of your fans has failed, and or it could be the lamp itself. Sony television will not power on if a fan is faulty. Open the back of unit and look at all fans to make sure they are running, if so then replace your lamp.

Sony LCD television will not power on.

I get 5 blinking red lights for about a minute or so before it powers back down. The Sony TV has a specific light that i presume is supposed to light up when the bulb is out. I'm unsure if this is what it is.
no picture, no sound. tries to boot with green light blinking a few times. then goes to red blinking light, six in all, then waits a few moments, then another 6 blinking red light.
Bulb was already replaced several months ago but we do have the TV on for long periods of time.

I see you've downloaded the video card driver, but how about the driver for the monitor? It's a long long shot, but I shall refer you to It's worth a shot, afterall I hate seeing parts thrown in the basement. Sadly your problem sounds far worse than a driver problem (which is probably plug and play anyway). It sounds to me like a monitor on it's last leg. Severe problems that happen gradually like you described point to something beginning to fail. First it takes forever to start up, then later you have to turn it off and on again real fast to get it to initialize, then finally it just craps out.
