On power up we heard a pop and simultaneously the green bulb (only the green) lit up for a second and went out, then the TV immediately shut off. Now, when we push the power button the green power light comes on and immediately there is a strange noise from the front of the TV and then the TV shuts off. After opening the front cover and powering the TV on, I discovered that the noise came from a blue spark within a clear glass part under the center (green) bulb. (I have a picture of this but can't figure out how to post it.) I did the diagnostic and the code 23 was flashed. Any suggestions? Any one? Please help? I can't afford a technician or a new TV.

is the new power supply voltage the same as the area that you left

Hi, It could well be the power supply that is in the back of your set. Have a repairman check it out. It's not a do it yourself thing. Good luck.

Hi,
Please check lamp in tv as pop sound seems broken lamp.
Did you replaced lamp in last 2-3 years in tv? If not, then its lamp that got broken and tv needs new lamp.
Lamp replacement procedure is written in user manual and its easy, please buy Sony original lamp for good picture in tv.
Thanks.

Your unit has some sort of PSU fault, or a problem that is shutting down the Power Supply Unit, PSU. This happens so that no further damage, and possible fire will occur. The sound is it starting up, shutting down, over and over.

You need to take the unit to a reputable service centre/man and ask for a firm "Quote" for the work to be done.

3 times blink shows lamp cover is removed or not installed properly on TV.
Please take out lamp inside TV and check, seems its broken as you heard loud pop.
Thanks.

If you still have red light , it means the temperature of the lamp is too much. Did you buy the original part number of the lamp.

When my lamp died the bulb literally exploded. That may be what you heard. Have you check the lamp? If the lamp is ok, the lamp's ballast or power supply might have blown.

it a fuse

Two things in your TV can make that popping sound. One is the bulb of course and the other is a capacitor. Have you pulled out the bulb to inspect it? My guess is that you have broken glass in the cooling fan, which is why there is a grinding sound. Most bulbs tend to contain the glass from getting everywhere as it's only the filament inside that pops creating little diamond looking pieces inside the lens. If a surge was strong enough or if the bulb was poorly manufactured, the whole unit can explode inside spraying glass everywhere.

If the bulb looks fine, the pop must've been a capacitor on one of your circuit boards resulting in no display. Since the TV still powers on, your power supply and it's fuse appear to be fine. Check the bulb first and go from there.

Lamp life is only a few thousand hours. Hopefully its only the lamp that made to noise. Don't turn on again until lamp is replaced.
