Where Is the Ballast.

Where do I find the ballast on this model TV? I replaced the lamp but still get a clicking noise. I believe its the ballast trying to power up the lamp.

The ballast is on the other side of the lamp compartment. the lamp plugs into the two short leads that are attached to the ballast. Its a small circuit board.

Replaced lamp in my HD 61Z575, but when I turn on my TV, nothing happens (no fan noise). After ~10 seconds, the Light LED starts blinking rapidly. Could it possibly be the brand new lamp? Ballast?

Hi,Osram lamps average around 3000-4000 hrs.Normally 1 -1 1/2 yr.I do think the lamp went out.The ballast is a possibility,when it's going bad it will make clicking noises or attempts to light the bulb.I recommend to get the Original Philips lamp for they average 6000-8000 hrs 3-4 yrs.

Samsung SP50L6HX, I replaced the Lamp but still nothing.


Hi, Samsung haves a known issue with the ballast, once you make a replacement of the lamp, sometimes its harder to ignite a new lamp that has 100% of gas inside than igniting a old lamp that has maybe 60% or 50% of gas inside. Just in order to ignite the lamp, the ballast needs to send some High Pulses of Voltage, as high as 15 kV (that is the constant clicking sound that you are hearing). In order to resolve this you need to change the Ballast Board. I tried to look for your ballast with your TV Model # at samsungparts.com , but nothing showed up. You will need to find out which ballast part # you have in order to find it online. To locate the ballast part # please check the end of this video, you only need to take the lower back cover of TV off. http://www.youtube.com/watch?v=0jr_9A5Xd2Q
Here is a link of a ballast I found http://www.discount-merchant.com/SAMSUNG-9137-008-08905-Lamp-Ballast-Driver-p/1138231.htm?Click=49915

Tv was working went off LAMP flashing and would not come on.


Lets go back to the beginning... What were the original symptoms? Was it just the clicking or were the lights on the front of the set flashing too? With the new lamp, is there any thing else other than the clicking? If not, then the problem is likely to be the ballast. The clicking could be the lamp attempting to "fire". With a defective ballast, the lamp won't fire and the set won't come on. If you choose to replace the ballast, DO NOT use the old lamp. It is relatively common for a defective lamp to smoke the ballast under certain conditions. Also, it is possible that the original cause was the ballast that failed and took out the lamp with it.

Please keep us posted.

Thanks,
Dan
