I would suspect a problem in either the backlight assembly, or the power supply that drives it. If it's the power supply, the part may be over $100.

SOURCE: sound but no picture
Most likely - the CCFL backlight is not getting the power it needs to come on. You can verify by shining a light on the front surface of the set - if you can just make out a dim image, then that is it. On some sets, the CCFL can be seen through the vents on the rear.

Five buck solution; If you have any tek skills at all and are feeling adventurous; UNPLUG THE POWER, remove the back panel; You will be faced with the mainboard. In the lower right quadrant you will see two small capacitors, like tiny yellowish coke cans. If these are bulging, there lies your problem. These must be replaced. If you have no soldering skills, take only the mainboard to a fixit shop and have them solder in the two capacitors easily found on line. No guarantee's but worth a try

I had this same problem with my 23" cello TV. It was a problem with the internal power supply - specifically the 12V output. It had fallen to 5V. I noticed that the three electrolytic capacitors (EC7 EC8 & EC9) had bulging tops as though they had been damaged. I replaced these and my TV is now working again although I don't know how long it will last. The three capacitors were 1000uf 16V types. I replaced them with 35V versions (which are physically bigger and a tight squeeze). Your TV repair shop should be able to replace these faulty components in under an hour.
