Sony sdm s73 screen black - green light flashing - no amber light

tlnwiayqydee, In terms of lcd monitor age, unit is VERY OLD. Cold cathode fluorescent lamps will need to be changed for new ones. Very hard to do for consumer/user!!! Best if you trade-in for new unit. Did you even look at the "date of manufacture" on back of unit? Look here for lamp information: www.rexim.com and www.jkllamps.com and www.lcdparts.net and www.lcdrepair.us You will need to also visit YOUTUBE for video clips of units being repaired. 12fixlouie

First check brightness and contrast settings.
If all good could either be your lcd back light has gone or the inverter. To check if its the black light shine a torch through the back of the screen to see if you can see a slight image on it, if you cant see anything the inverter board is faulty and to repair needs to be changed.

After being on a little while, the screen goes black (no audio as well) for 20 to 30 seconds. Green light stays on. Then, picture comes back on and takes a couple of seconds to get up to full brightness. About 5 seconds or so after the video comes back, the audio returns.

Until this morning, has only happened a couple of times a day, now happening more often. About 3 times in last 20 minutes.

KDF-E55A20 is about 3 years old.

Hi Suzee,

Is the green flashing on the tower or the monitor?

If it is flashing on the monitor, then it might be tht the monitor is not gettign signal from the tower.
To check, disconnect the monitor from the tower and check the monitor. If you get a msg on the screen like no input signal or check video cable, then 99% monitor is fine.

Check for the power supply light at the back of the tower.

Disconnect everything from the computer and then press and hold the power button on the comp for about 30 seconds.

Then connect the cables and check if it is working.

same problem... tv turns on and off repeadly while the green light flashes. seems as if the tv keeps restarting. please help.

bratty, do you have a pic on which capacitor this is? Also where I can find a replacement one.

My monitor is doing the same thing, nice and bright for 1/2 a sec then goes super dull, you can barley see anything.

Thanks,
Jake

Thanks for your response. I actually sent my monitor out to guy that does LCD repairs for cheap. He changed out the video board and did repairs similar to yours but still couldn't get the monitor to work. After some more testing, he found that one of the chips that contained Sony's proprietary firmware had gone bad and said there really was no way to replace the chip. It definitely seems like we had the same problem, so I thought this information may help. I'm sorry that you paid so much for repairs that didn't solve the problem.

Sorry to say, it sounds like a bad picture tube, But could be also the capacitor that filters the screen voltage on the crt drivers. In all my years though, your complaint has been the picture tube. Good Luck.

Most likely you inverterboard went bad on the monitor.

check the brightness and contrast from the menu on the monitor try increasing it ... the problem will get solved...
if same problem persists contact ur near by experrt technician he may tell that the tube is gone he must recharge it....
