Make sure its an original Osram or Philips bulb inside the housing. If its a cheap lamp it will act this way. If it is an original lamp, then you may have a power supply issue. It shouldn't affect your TV but you may want to try resetting the lamp timer by following the instructions that came with the lamp.

TY-LA1001 Timer reset

While pressing the VOL- button on the projection display, hold down the number 0 button on the remote control at the same time for more than 5 seconds.

Was the prvious lamp still working?

3 blinks indicates lamp door is not on or has not been reinstalled properly. This also could mean the lamp door switch has failed itself. Try removing the lamp door and putting back on, if that doesnt correct the problem then I recommend having the switch replaced.

green green is power on, normal
then it tries to light the lamp, but it can't so the protection circuit comes activated.
you get red and green blinking

Then it goes to standby, red and off.

so something has happened to the lamp, or lamp ballast power supply.
Take the lamp out and check if all is OK with the 2 terminals in the connector, and the leads to the lamp are intact.

Failing that, I would suspect the ballast lamp power unit

You tv used lamp XL-2400 or also known as F93087500. It is very common for this bulb to fail and have the exact symptom you are experiencing. I cant count how many times I have seen it.. Replace the lamp with either the exact Sony or an OEM and you will be back in business..
Good Luck!!

This is a common problem caused by a busted bulb. Please replace the bulb of your TV set.

Hi,
Symptom shows Lamp is weak in result and causing restart of TV again and again. Your TV requires new lamp as per following part number...
A1085447A* LAMP BLOCK ASSY XL-2200U
It is available in Sony Accessories Store for $200 and replacement procedure is written in instruction manual of TV.

Always buy Sony original lamp for TV and avoid aftermarket / cheap lamp for TV safety.

The lamp can cause the picture to cycle without spitting out a lamp error. I'd replace the lamp and clean out the dust/dirt from fans, etc to hopefully resolve your issues.

How many times Red Lamp flashes, its important as it shows problem and its location in tv. Below is detail of lamp blinks and you may know the problem area in tv by counting lamp flashes.


Need further help, let me know.

a tv has two components, firstly a power supply produces high voltage to trigger a line transformer, in turn a transformer produces smaller voltages. firstly check if the ht is constantly been produced from a supply, if this is there than go to a line transformer, and check voltages at the output.
