If you replaced the lamp you must need to reset the lamp hours. then if already done but still shut down you must check if no bad or burnt parts at the lamp ballast board. then make sure the fan is working.

SOURCE: My Sony 55' DLP had a bulb out. I replaced it but now it starts to power up then quits. The light on the front flashes 3 times then repeats. Help

depending on model number most of these it means lamp door not closed---but several the door is warped from heat--a class action suit was settled and ended early this year.

with door off hold it edgewise to see it is not warped---note the plastic peg on the back of the door--it engages a lever when door is in place---what I do is with a Q-tip or something not metal engage the lever and hold it forward---if set now comes on you need to replace the door.

Some models got so hot they melt the door badly.

Double check lamp, make sure it's made for your set and not just a replacement. Also look for blown fuses that goes with the lamp.

We had the same problem. Let it be and now the tv won't turn on. If I understand correctly from what I've read it's the optical block and they seem to be just as much as a new tv.

I have had a Kenwood VR-407 reciever for almost 9 years now but it has just started cutting off. The small power/standby light above the power button goes off when I power it up but then it shortly...

If you've already disconnected the speakers then I suspect the fault is internal on the amplifier and the unit is shutting down to protect iteself.

The fault with most amplfiers can normally be traced to blown or leading capacitors (bulge on the top or liquid around base) which can be replaced for little cost if you've got the technical ability and equipment to desolder and resolder components on a PCB.

First thing to do would be to remove the cover and check the capacitors as detailed above.

I have a Sony VPL-ES1. After I had moved my beamer from the first to the second floor it won't power on. It's connected to the power well. I've had this problem before but I would like to know...

ensure that the projector goes through the cool down cycle, for example the fans stop running, before you unplug it. Unplugging it will cause it to into power failure mode which will not allow the lamp to turn on until the bulb reaches ambient temperature. it will also extend the life of that very expensive bulb. take the extra time to let it shut down before you unplug it.

I have a Sony Wega 55 inch for about 6 years. I have replaced the bulb twice before. I just got another bulb in the unit. It now works for awhile. It occasionally is shutting down with the 5 blink code. I...

5 blinks, pause, 5 blinks, etc. means "Lamp driver error" and the probable cause listed is "Lamp driver defect".This is the starting point for a qualified service technician.Even so, the actual problem may be the lamp. Did you install a genuine Sony lamp assembly? These sets are bad for the lamp driver and optical block, which Sony has extended a warranty on these sets due to the mass problems that they have had with them. If you haven't contacted them yet please do so and talk to them about a warranty on your set. Sony tells me that while they extended the warranty through 3/2011, so please hurry on this.
The parts you need run between $225.00 and $315.00 depending on what boards you need. IF Sony won't honor the warranty or at least work with you, you may consider a new set, these will only get more costly to keep repairing. I Believe in Sony, its not all their fault, there were a lot of bad electrical supplies sold to the electronics industry a few years ago and they simply don't last.
