The i have Sony Vega projection tv. the lamp light comes on after a while when i turn the tv on. i can hear the sound but can't see anything.

CHANGE THE LAMP

Hi,
Lamp is getting weak and TV shuts off and turns on itself because of weak lamp in TV that you see picture and sound fades away for some time until TV reboots.
Replace lamp in TV to solve this issue. Lamp replacement procedure is written in user manual and its an easy work.
Please buy Sony original lamp for your Tv safety.
Thanks.

MY SONY PROJECTION TV WENT BLANK WITH NO SOUND GREEN LIGHT WAS ON WHATS WRONG

Hi,if your tv is between 2-4 yrs and you don't hear any strange noises it might be time to replace the lamp.This will be the lamp you need: XL5200 The Original is made by Philips and it's the best lamp in the market.You can find it on discount-mechant .Good luck and God bless you!

Please intimate exact model of your Sony TV and also mention how many times red light blinks as there would be pause of 3 seconds in blinks so count pause to pause and let me know to find out problem.
How old is this TV and did you replaced its lamp?
Thanks.

Hi,
If it is Sony KDF-50E3000 TV then its symptoms of weak Lamp that requires replacement.
You can purchase required XL-2500 Lamp from Sony Accessories Store.
Always buy Sony Original Lamp for your TV and avoid aftermarket / cheap lamp.
Thanks.

You probably need to get the bulb changed and or a new wpower supply board for the TV. How old is this?

Anything that sounds like electrical crackling will be coming from either the lamp or lamp driver/ballast boards or their interconnections. The lamp should be examined first as this is the most likely cause.

You are hearing the spark gap mounted on the lamp ballast board. If you can hear that sound, that means everything in the lamp driver circuit is working except the lamp!

Get a new lamp.
