One thing is to make sure the inverter board is unplugged when testing the voltages. A shorted inverter will shut down the power supply if the fuse dosen't blow first. There are fuses that don't look like fuses so they can be missed. The next thing would be to look for a connector from the main to power supply and see if there is a pin labeled power on or p.on or similar. The main board should turn this line high(5V) when you push the power button. If not you probably have a bad main board. Unless you can find good used boards they are both expensive. Around $200 for PS and $300 for main.

To some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS]. In such cases, the power supply board might need replacement. To some models sets, the back-light inverter and SMPS section circuit will be integrated at its main board itself. If so; the main board should be replaced. To some models of sets, all these section circuit will be integrated at its main board. If this is the case, you have to replace the main board.

Black screen, only sound


common problem with LCD TV is a dead screen but there is a sound. so the problem is always coming from inverter board inside the lcd, inverter board controls the ccfl bulbs that illuminate the image in the screen. there are 4 or more bulbs inside your screen supplied by inverter board. you can see this inside at the back of the screen there are 4 boards inside, display driver board,power supply board ,inverter board and input board, this could be repaired or replace.but you need some tools for opening the case and test equipment. add comment if you want some help.. hope i help you.... thanks.....

My LG 21 int ch flat screen takes time to show pictures,the red button appears on and sound will be heard but their will be no pictures,they appear after some time please help me.


hi,

You have to check the back light of your lcd TV. All lcd screen have a back light to illuminate the pixels. you can conform is the back light is faulty or not by watching the lcd screen nearby. Watch can you see any image (negative image) on the screen. you have to look very closely. if you see any image on the screen then the back light or the back light inverter is faulty.

first of all check all the electrolytic capacitors in the power supply and back light inverter board.If available then replace these capacitors first.

You have to check the back light inverter board. Normally in lcd monitors you can see three circuit boards. power supply, mother board, and the inverter board. If available then try to replace the inverter board. There are high voltage transformers in this board. There is a chance for its winding get short. You will not get the transformer in open market. Try for the inverter board .
ok

My compaq presarion c-500,it is showing power on but display is not showing on.


Try an external monitor & see if it will work. If it does, then this might be a sign of a faulty LCD cable or screen inverter board.
The LCD cable transfers data signal from the motherboard & video card to the LCD screen. It also supplies high voltage DC power to the screen inverter board. The screen inverter board works as a power supply for the backlight lamp mounted inside the LCD screen. It converts low voltage DC power to high voltage AC power needed for the backlight lamp.
