Sylvania lc225sl9 22in lcd, power but no picture or sound

SOURCE: no picture and no sound just a blinking stand by light on front of my sony kdl40s2000 lcd tv

I have a Sony KDL40S2000 and three months out of manufacturer warranty my TV made a clicking noise similar to feedback in a bad sound system and went to black screen. The error was not recoverable and four blinking lights were seen by a technician. I bought the extended warranty from my store, so I was covered. After one month in the shop, the technician brought my TV back today and told me the panel was replaced which would have cost me 1000 dollars if I wasn't covered by the store warranty. I read on another site the four flashing lights can mean a bad inverter. I don't know enough about TVs to tell you if the panel and inverter are one in the same, I just know you need to get it repared if you get four blinking lights at a huge cost!

Try replacing C51, a 10 microfarad 16v. surface mount electrolytic. It's near IC23 on the upper center of the board.
This part had high ESR on a couple of sets I serviced which
kept the power supply from starting.

Go to http://www.fixya.com/support/r741402-polaroid_flm_373b_lcd_tv_black_screen. Stiv0 posts the fix at the top, but go down about 10 posts or so and read mine (BlakeFromGa). I have some slight differences to my fix and a list of what you'll need.

It can be the power supply is unstable due to bad DC filter caps, or it is sensing short circuits caused by backlight board, you will have to take it apart and start by visual inspection first, look for bad caps iwth leaking/bulging tops (caps can look OK but can have high ESR). Then you need to do voltages checking.
If you are going to DIY and have proper tools, electronics knowledge, and know safety precaution then please read on:
