42'' lcd turns on no picture/menu

I have a 42''Philips lcd hd tv. Its about 1yr 6 mos. old. The model number is 42pfl7432d/37. Anytime I would lose electricity, a pop sound would come from the tv as it shut down, then it would make a pop sound again when electricity came back on. (Like a light bulb popping)On halloween (2009) the electric went out, tv made a pop sound, popped again when it came back on. The next day the tv turns on but no menu, picture, sound. The input appears quick then disappears. anyone have this problem?

Your tv is being attacked by electrical surges which seem very violent and has already damaged some logic controls. Please invest in a AC filter which will protect your tv from such spikes....... but first you need to get your tv serviced from the electrical damaged it has already suffered.

I have a 42" Philips LCD TV model 42PFL7432D/37 i accidentally throw a screw driver hit the screen, now the screen has whole bunch of lines and distortion images, can you help me? Thanks Ken
Your lcd screen is cracked and the only repair that you can do is replace the screen. This is not easy to do and usually not cost effective, assuming an exact replacement screen can even be found.
Sell the tv for parts on ebay or craigslist.

I HAVE A PHILIPS LCD TV MODEL 42PFL5432D/37 WITH THE LCD PANEL BROKEN, CAN SOMEBODY HELP ME ON THIS ISSUE?
First, the used screen will be more than $300 plus shipping, new is almost impossible to get.
Second, you need to get the exact model number as printed on the sticker on the LCD panel since you will have to transfer all the boards from old TV to the new panel.

I myself will not do it.

My philips lcd tv has sound but no picture what is
change the backlight (cold cathode light) on your monitor.. If you are able to open the back of your lcd monitor carefully, the backlights are located at the upper and the lower part of the edge .. replace it with conventional cold cathode lights(protective tube was removed)... there are also instances that backlight was good but the ballast transformer is burnt. Replace the ballast. Its very cheap to replace that.

Received new backlight inverters 6632L-0348b and
I wouldn't unless you're sure they match the particular model. Each of them are different depending on size of set. This can be verified by seial number version(ya1b, ya3b, c and so on). If you were to try this you might fry the backlight, requiring a replacement panel. They supply different voltages........Please be careful, can be lethal, 1000vdc or more........Good success, Meder's Tv
