My LCD TV has been getting progressively worse - instead of turning on - it will give off a buzzing sound and go to standby mode. (without turning lamp etc on) For the last few months I have been able to finally get the tv to turn on and when it does - it works fine. However, now it will not turn on at all. It will attempt to turn on several times and then the fan will turn off and the red light will flash 5 times. I have removed the lamp (sylvania) and reset it - but no change. (also- the lamp indicator has NOT ever lit up - so I believe the lamp is still good - when the tv USED to turn on - the tv worked fine).
Through my research, I believe it has something to do with the spark gap to the lamp driver board. The buzzing sound appears to be the machine's attempt to send power to the lamp - but "it ain't a workin'!"
I have heard that several people have this problem with this tv but Sony has not issued a recall.
Is there anything I can do that will not cost $200 + for a repair call?

Sounds like you just have a bad lamp. The buzzing sound would be the spark gap on the ballast trying to fire the lamp. Access door for the lamp is on the side in the rear. A few screws and pull it out, you'll prob find that the glass has broken inside. New lamp part# is TS-CL110U and around $170
How recent? That lamp should have a 30 or 90 day warranty. From what you are describing, the lamp is a dud. The cycling occurs when the lamp burner gap becomes too large after warm up. Listen closely to the sounds the TV is making when it is trying to bring the picture back up. Is there a buzz or gurgle sound coming from the lamp area? That's the TV trying to ignite the lamp. Get a new lamp or your money back for the one you installed. I hope this was of some assistance.
Well we need to have in mind that a generic lamp will give you 3500 to 4500 lamp hours and the Phillips will give you 6000 to 8000 lamp hours ,The lamp itself typically uses AC current and about 15,000 volts to ignite the lamp's mercury vapor gas. The gases inside the lamp react when electricity charges up the mercury gas creating very bright light. The voltage drops to keep the flow of electricity to the lamp. The symptom of a bad ballast is that you could hear a constant CLICKING or electrical BUZZING sound,my recomendation is to take out the lamp to physically check for any sings,(shatter fillement,black or grey spots in the fillement or smoke ) you can get good deals at http://www.discount-merchant.com/?click=52978 Please keep us posted,
That buzzing sound is this kind of Tv LCD Projection, is most likely a issue with the ballast (only if sound cames near the lamp) you can check that just follow the cables that are connected to the lamp, take out the back cover of tv, and keep pushing the switch cover (if not tv will not turn ON). and check if that sound comes from the only board connected to lamp. if it does, you are going to need a ballast very soon.
If all 3 leds blink, it can be the lamp, ballast (lamp driver), color wheel, or dmd board (all are engine parts = engine failur). its usually the lamp, but you can listen to troubleshoot. when it turns on, you will hear the fans come up (humm..airflow noise), then you will hear the colorwheel (high pitched squeel.. it will come up to speed) and then the ballast will fire up the lamp.. if the lamp doesn't fire, you will hear the spark gap fire (a 1 second buzz noise indicating bad lamp).. the gap will fire 3 times, they tv will then retry again and again until it shuts off and kicks out the error. this power up path will help you listen to find your problem. i can assist further.
The buzz is made by the ballast who's trying to start the lamp who's burned. So replace the lamp. The part number is A1606034B or XL2100. It's very easy to do it by yourself. If you don't have the lamp send me a message on email@example.com
