It's possible that your ballast might have gone out or it has very poor voltage. A ballast is the one in charge of sending all the energy to the lamp so it can stay on.discountdashmerchantdotcom

HDMI makes black screen


IT sounds like the ccfl tubes (the bulbs that help light your tv) are going out. Think about replacing them. You'd need to take it in to get this done. Also, it may be cheaper just to replace the TV entirely, given the cost of replacing the tubes.
Good Luck!

Hi, Mary.

This sounds to me like it is a bulb issue, and not something worse, like failed capacitors.
If that is the case, then yes, it is worth repairing it.

You need to get the old bulb out, either by removing it yourself, or by having someone take it out for you, and the take the old bulb to Fry's or BestBuy.

They both keep tv projection bulbs for flat screen tv's in stock.

I hope that I've helped you understand what is going on, and that it helped.

Have a nice day, and good luck.

I finally wet out and bought the tv repair manual. Thought the problem had to be more than the bulb because i was losing sound too. Everything in hte repair manual brought me to the bulb or the ballast. I ordered a replacemant bulb. I spent about 150, which included overnight shipping. I replaced the bulb just before Thanksgiving and haven't had any problems as of yet....

Black screen


Sounds like the bulb again. In the manual it says that the power light flashes to let you know that the bulb is bad. When I got a replacement bulb, I noticed that the wiring on it was opposite of the one on my set and had to change the wiring to match my set.
