KDF46E2000 shuts off - 3 red flashes

Hi Ron....You posted a solution to my problem earlier but if the switches seem to be working (according to the techs), could there be something else on the circuit that could be causing it to shut down intermittently. It's been doing this for about a month now but for a stretch last week it worked the whole week until the tech came and opened up the tv to check the switches and right after he left it shut down on me within a half hour and now I can only get it to stay on for about five minutes at a time. I have to unlock and lock the lamp door to get it to come on again. The tech is calling me tomorrow to find out how it was over the weekend but he said he'd order the two boards that the switches (lamp/lamp cover) are connected to if it was still acting up. Hopefully that's where the problem lies. Any other suggestions? Thanks,

    Hi Ron...I am forwarding your two comments on to them tomorrow to see what they think. I had the optical block replaced due to fuzziness on the left side of the screen and this problem has stemmed from the replacement. I did not have this problem before I had the work done. The tech doesn't think it's a warped cover because Sony seemed to have fixed the heat problem on their later models like mine. I did look at the cover and the tabs appear to be in good condition with no warpage in the cover. He wants to order the boards and go from there. I will let you know what comes out of this. The service provider is Northern Electronics. Thanks again.

My first question is did you have this problem before your set was repaired the first time or did it occur after a tech took it apart?

The switch could be flakey evidenced by it working after the door is removed and reinstalled, but I would think you would have seen that symptom before the TV was repaired. BTW- what problem did you call them out for service on?

The door switches are very delicate and Sony warns techs in their training videos to watch for this when they do an optical block swap.

If I was repairing the set, I would meter the switch for voltage at the time it fails and if I saw voltage the switch is defective or the position of the switch board or optics is changing. If no voltage was measured at the time the set shuts off and the red light still blinks 3 times, then the board the switch goes to could be bad.

Who is your servicer if you don't mind me asking?

The root of my problems was the T1 mount. Replaced that and my problem seems to be fixed. Make any sense? Thanks for your advice though...

Red light flashing and ps3 then turning off. Now when turning on ps3 the red light just flashes and will not do anyting.

Hi there,

I did a bit of research for you. You can try one of these:
1- Check for loose cables, or un-plug them and plug them back in.
2- Restart Your Console 3 times after letting it cool down.
3- Take out your hard drive, and put it back in. (If this seems complicated to you, try the guide I mentioned earlier.)
Beyond that, it's a problem with your HDD overheating. If you can't cool it off, you need to call Sony at 1-800-345-7669.

My display keeps shutting off five minutes after starting to watch TV- the sound continues, but the screen is black and the red warning light flashes


Please check the sequence in which your warning light flashes.

I will tell you what might be the problem according to the fashing of warning light,

Flashing repeatedly --- Improper voltage supply
Flashing once --- Malfunctioning of fan
Flashing twice ---excessive temperature
Flashing 3 time or more--other problem

When flashing occurs please remove the power cord from receptacle and inform your dealer about the flashing sequence.

Sony rear projection tv keeps shuttin off

If you have correctly seated the lamp door, then check the door itslf near the screw that tightens it down. There is a little tip that sticks through a hole to engage a safety switch. Either the tip has broken off or the safety switch has gotten damaged.

Red flashing light on ps3

When the light flashes red and you ALSO see the green light on too this indicates that the system is getting hot and you need to switch off and let it cool down.

if you switch on get the beeps see yellow light briefly then flashing red only this indicates failure.

The system has shut itself off to stop further damage ..... supposedly caused by getting hot .. maybe fan failed .... only thing that can be done is to contact Sony for repair or replacement.

I know this post is old but thought the info could help others ...... I hope you returned your PS3.
