It sounds to me like a power supply problem. Specifically the 5V rail. Examine the power supply for bulged electrolytic capacitors and also put a volt meter on the power supply rails and see if there is any sagging.

Hi Jhun,
As a general rule as soon as you switch on the TV, the power supply must produce stand by (sb) 5V or 3.5V as per the TV's design. Next, when you give power on command, the power supply should produce power on 5V or 3.5V, 12V and 24V or some other voltages as per the TV's design. All this is printed on the power supply pcb in most TV sets. I hope this helps.

nope

Pin Name Color
Description 1 3.3V Orange +3.3 VDC 2 3.3V Orange +3.3 VDC 3 COM Black Ground 4 5V Red +5 VDC 5 COM Black Ground 6 5V Red +5 VDC 7 COM Black Ground 8 PWR_OK Gray Power Ok is a status signal generated by the power supply to notify the computer that the DC operating voltages are within the ranges required for proper computer operation (+5 VDC when power is Ok) 9 5VSB Purple +5 VDC Standby Voltage (max 10mA, max 2A in ATX 2.2 spec) 10 12V Yellow +12 VDC 11 12V Yellow +12 VDC 12 3.3V Orange +3.3 VDC 13 3.3V Orange +3.3 VDC. ATX V2.3 / EPS12V V2.92 both define that the PSU has to use remote sensing to compensate cable drops on the 3.3V line. Because of this there is an additional brown cable crimped together with the orange cable either to pin 13 (ATX) or pin 1 (EPS12V). 14 -12V Blue -12 VDC 15 COM Black Ground 16 /PS_ON Green Power Supply On (active low). Short this pin to GND to switch power supply ON, disconnect from GND to switch OFF. 17 COM Black Ground 18 COM Black Ground 19 COM Black Ground 20 -5V White -5 VDC (this is optional on newer ATX-2 supplies, it is for use with older AT class expansion cards and can be omitted on newer units) 21 +5V Red +5 VDC 22 +5V Red +5 VDC 23 +5V Red +5 VDC 24 COM Black Ground /PSON activated by pressing and releasing the power button while the power supply is in standby mode. Activating /PSON connects the power supply's /PSON input to ground, thereby switching the power supply to full-on condition.

if you suspect lightning or a power surge that caused the problem, if it were lightning could have effected the power supply board, or if it was lightning it could have went in on the cable or antenna connection. to narrow down the problem, check the fuse on the power supply board, if that is ok then with a volt meter check and see if there is 5V volts going to the signal board, that is the board with the antenna connection, one of the plugs that go to the board probably has writing next to the wires in the plug, if no 5V probably the power supply board bad, I almost forgot, when you take the back off look for burnt parts. if you have the 5V going to the signal board now the problem could be signal board or power supply.

Hello.
First of all you need some electronic repair experiance,
You have to disconect all f the power supply that going on 5v(rgb processor in moust cases)and 13v in most cases ccfl inverter(back lite ) with his driver.than have to mesure the voltages.
-Replace the capatitors in 13v line.
if the problem persist try to replace the diode one for 13v with one for 5v,they should be the same type.and check the voltage 5v and 13v.
if the problem is still on 13v look for the problem on the 13v line.

open the back cover of you tv you can see the power supply there.using a multitester measure the output of the power supply wether there is 5 volts output...check the connectors specially the RGB fit them to the terminals...the power supply outputs are 5v,12v,and 24 volts if one of them is missing replace the power supply..

good luck!!hope this help you..

your rate is important to this help.tnx..

Yes this is a good list of the voltages to be expected from a newer power supply on just the main header

um what you want lol:?
