  • eugenebarry Sep 01, 2008

    You do not appear to have answered my question, this power supply is built from many components some of which fail from time to time, they are all soldered to the board which means they can be replaced. ageing components cause failures. The faults can usually traced to resistors, capacitors power transistors transformers etc. through the use of schematic diagrams.



    Change the power supply or get a technician is not the expected answer from a television technician

Stuck in standby can be caused by c877 and c878 both box type caps 15n 400v. But the fault which is causing most of this is Q837 suface mounted transistor type bsh103 which is connected to pin 8 of sg3525a control ic807.

    uses common psu type 17pw15-8 vestel . disconnecting collector of Q837 will allow set to start - recommend replacing . q837 is in the soft start of ic825.

Try changing the two 15n caps c877, c878 at the top left of the psu.
Or the 1000uf c806 at the center of the psu

When switch on power LED comes on and goes off in about 7 seconds and then the STATUS LED comes on. Please tell me what I can try.


if you have the habit of leaving your device in standby mode (switching off in remote only and switching off the power supply), you have to consult a service perssonnel and get your circuit chip dealing with the power supply inside your device. it might have busted up if you have the practice that i specified. please do not leave your device in stand by mode for a long time..

Stuck in standby


There is a "reliability kit" sold for these which consists of 8 electrolytic capacitors for the power supply that may cure the problem. Other times more extensive damage to the switch mode power supply needs additional parts You can try replacing the 4 470Uf/ 35v and the 4 470Uf/ 25v caps.

Re: standby mode???


No really the standby mode dosent mean the sets fried or unrepairable. It just means that the sets in a shutdown mode till a power supply problem is corrected. They have shut down protection when the power supply dosent regulate the b+ and if it didnt shut down it would give off tons of X type radiation. thats just a safty on the set. seek a pro to assist you in repairing the set. Good Luck
