Hi I have solved the problem. Thanks.
Now I have a new one.

Astar LTV_3001 flat panel tv power supply is not giving me the 16V I need to run the audio amplifier. I need the identity, type, something on the Q12 transistor.

This transistor is also linked to an N5551 transistor. I also replaced all the capacitors eg. 2) 100mfd 450V, 75mfd 450V, all 100mfds, 3300mfds and 2200mfds which is a regular problem with these board.

HELP PLEASE

My Samsung LN-S2651D has sound but no picture


Hello,

Check with Samsung, this model should still be under the 3 year warranty. You are having a problem with the backlight power supply. You can look on the back of the unit for the manuf. date, if its less than 3 years then go to www.samsung.com and process the online service request form.

I hope this helps,if so please rate our solution.

How hard it is to replace by yourself main board Samsung LN-T4065


You need to do some more diagnosing of the problem. If you get sound and change channels take a bright flashlight and place it again the screen. Look for an image around the edge of the flashlight.
If you see an image that means the LCD controller board (TCON) is probably good.

The problem is probably one of three causes;
1) Inverter board is bad
2) CCFT (cold cathode fluorescent light) are bad.
3) Power to the inverter board is bad. You can also check the connectors.

Samsung 40 inch LCD LNS4092D No Picture


You need to check the back light is still on when the screen is blank (check through the back).

If the back light is on, need to change the Powwer Board.
but,
no back light, need to change the inverter.

You have to have a RF cable hooked to the tuner on the back of the set, should be 2 tuners, hook up the cable to either one and the channel option will be selectable
