The main power supply regulator section circuit fault. Either it will be a separate board, or the part of main board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Pull up older posts.

It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.

Tv screen goes black ater 10 seconds


there could be several things causing this, most often it's a defective inverter, or a bad CCFL lamp. You could also have a problem with 24vdc output from the power supply, or "backlight on circuit from the main board. Get a proper diagnoses.

This is known as SLEEP MODE problem.

Simple solutions:
1. Get a power surge protector / strip.
2. Plug your TV power cord to the power surge.
3.Then turn-on your TV using the remote control. Just in case it won't go all the way to normal state.
4. Turn-off the switch of your power surge like 5 times with an interval of 3-5 seconds.
5. Then repeat step 3 and 4.
6. These step is done to over-ride the sleep mode.

Westinghouse TX-47f430S Will not power on. LED power indicator flashes blue then to red. Found some fluctuating voltage in the PS and replaced a ceramic cap and it cleared up part of that issue, but it...


There are some bigger electrolitic caps in the power supply that can cause this problem also. Testing with a ESR meter while they are in circiut doesn't always work, they need to be taken out and tested with a cap checker.
