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.

SOURCE: power light just blink on my sylvania lc320ss9a lcd

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:

SOURCE: sylvania lc320slx lcd power light goes one then off

I recently repaired this exact TV that sounds like the exact problem. First you can take the back off and unplug everything from the Inverter board. Then try to power on the TV and if the green light comes on, and stays on, then you know the problem is in the inverter board. My problem was in the inverter and I found Q1500 (N Channel MOSFET) shorted Gate, Drain, and Source together. It's a simple part to replace but a difficult part to find. If you need help finding the part, I can direct you to the place I got mine for $3 and $8 shipping. Just for safe measure I also replaced Q1550 that is the same exact part on that board.

How do you fix a flashing green light and no picture or sound?


These blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices.

42 inch philips lcd no picture no sound


Sometime a no picture, no sound still has the power light or some other led blinking. The blinks might be an error code that will isolate the problem.

In general on LCD TVs with no picture, no sound, no blink code, the main power supply has failed. The capacitors weaken and when bad enough, damage the power supply.

If there is a blink code, the most, if not all of the power supply is OK and the blink code could point to the problem.
