This is going to be one of several problems. Very first think to check is fuses and capacitors. Then I would start with the power board. Check your voltages on the in and output side. If they are all good I would go to the logic board. That is the small board and pretty inexpensive. From there you have to go to the TConn, but I don't think that is it. The next step is the X and Y board. It is most likely going to be the Xboard. If you are not getting audio or video then you can unplug the logic board where it connects to the main board. If you get the sound upon turning it on with it unplugged then your logic board is one of the things that went bad. Most cases you will have to upgrade the firmware with your new boards.

You can't get into settings with a remote. All televisions HAVE to have a remote. Basic functions only, on off, volume and channel change.

Hi I ve a sony KDL-40W2000 stuck on stdby red light flashing 4 times the stop for 3 second ??any advice please
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. http://electronicshelponline.blogspot.com/
Blinking codes details to many popular brand TVs are given. Surf the site with patience. If blinks continue without any pause, the main board is faulty.

MY 42 in ultravision will not power up. The red stdby light is on but when turned on it does nothing. Just stays in stdby mode. Any suggestions? Power supply, fuse, etc...
Plasma and LCD TV sets are prone to having capacitors in the power supply section fail. This is the most likely cause for the probem you describe. When capacitors fail your will commonly see one or more of the following symptoms.
  • No video, Power light is on or blinking.
  • TV is making a clicking noise.
  • TV takes a while to come on
  • Screen is very dim or flickers.

Again, You can get a power supply repair kit with the parts, detailed instructions, and support from sites such as www.TvRepairKits.com . Or just click here to see more details on their kit.

Here are pictures of capacitors...Notice that the ones below look bloated. They have failed and will need to be repalced.

Have no stdby lite and wont turnon fuse is good have
This is a commaon problem. It seems that your unit has some sort of PSU fault, or a problem that is shutting down the Power Supply Unit, PSU. This happens so that no further damage, and possible fire will occur.
You need to take the unit to a reputable service centre/man and ask for a firm "Quote" for the work to be done.
