Check the remote control for its infra-red emission. Check it with fresh batteries. Check by pressing all the buttons on it; and see whether all of it generates infrared signal while pressing. If it is found OK, check and replace the infrared sensor inside the TV. If you wish to get some details; check the site linked here. It has details about how to check a remote control; by one among the post. Surf the site with patience. Pull up older posts. http://electronicshelponline.blogspot.com/ If the remote control is found OK; check and replace the infra-red sensor inside the TV. Contact any service technician

It is probably the capacitors on the power supply. Check them. I think there are 3 in a row. They are red in color and 450W. There is also a larger one next to them but I do not remember the volts.

The 5vdc standby is working but not the 12 or 24v?
You need to find out if the power supply board is getting PS_ON signal from the main board to turn on the 12/24vdc power supply section.
Please read my guide to get some understanding first.

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.

My Sansui 32" Model LCD32hbw got stuck with the


Sure the power supply si working and the processor seems struck up to trigger the power but is not responding to the remote. So it is important that the main processor is checked to fulfill the working. Check for the +5 rail voltage, check for the input /output data, check the remote feed of data and the crystal oscillator.
It is possible that there is a failure around the processor or the memory.

When i go to turn my tv on all it does is blink that it is in standby mode. The individual i got it from had a surround sound system hooked up to it and i dont know if they have a remote. They are looking....


The first thing you need to do is to check whether your power supply is working well.
To do this, you need to open the back cover of your tv.
You can immediately reach the power supply. Test the power output using a multitester. There must be an output of 5v,12v, and 24v.
24v is for the screen to lit up.
5v is for the the cpu supply.
12v is for the audio...
You can repair the power supply if it is not functioning or buy a new power supply.
To repair the power supply repace the regulator transistor,the opto isolator, the ic that gives the signal to the opto isolator and check for open resistor near the regulators.

I hope this will help.
