Not coming on

hi could be bad capacitors in the psu board,thanks

shaun

hi Tracie,
is the set making a clicking noise?
is the power light flashing on the front?
or no power light at all just dead?
if the set is just dead, just put your ear to the back vents can you hear like a very faint screaming noise and can you smell and burning in the vent?
if so it just could be capacitors on the power board.
if its clicking the that will need a service kit on the power supply board.
if the power led is flashing then you will need to count how many flashers from start to finish when you first turn set on.
hope this helps.

the tv need for servicing, the cause is either bad regulator transistor in the power supply section or shorted horizontal output transistor. that is why the main circuit board doesn't get to turn on. to do the repair just ensure you have knowledge in repairing tv.

Powering up do you hear the relay click then you may see the display flash (not necessarily), but then the TV clicks back into standby mode. If so there is a component failure.
will need diagnosis by a repair shop. Too many different components it could be for me to guess. but
the common repair kit containes1 fuse (F302), 1 diode (D304), the power resistors (R927 and R929 for the board revisions with these two resistors) and the IC301 voltage regulator IC.

Hello
The power supply section to your set has the fault. If you come over me by Fixya paid service purchase, I'll assist you to repair your tV by yourself at home. OK.

its a clicking of switching relay. cannot power on due to power supply failure.

most times then not it's the capacitors on your power board that blew there for not supplying the tv with enough power if you open it up and check the capacitors it should be leaking some kind of liquid or the tops have bubbled up. its an easy fix cost>>2 dollars each

hello..i think you have very big problems inside on you're TV you need a Electronics Technician to see inside the real problem.my tips is located in Power Supply Regulator..Can i know what kind TV Model???thanks

Solution1:
a)Inside the tv there are microswitch CH+- Vol +- power, menu: when the ones are faulty," tv tends to behave at its own", change them, of course before to buy'em, unsolder th'em and try with the remote, tv has to work with out'em.

Generally, if a Plasma Tv is not coming out of standby, it means either the main board is faulty (most likely case) or Power Supply Board is not giving enough power to Main board to switch on the TV. In your case, I think it's the main board (aka Motherboard). Sometimes it's hard to tell to whether ceremic fuses are blown off by looking at them, so it's best to check with a multimeter. Check the fuses in the PSU and also whether it's outputing correct voltages. Also, can you hear a clicking noise right after you've switched on the TV or pressed the power button in the remote to make the Tv go from standby to ON. A clicking noise means one of the boards is shorting out. In your case, I don't think you'd hear a shorting out clicking noise, and I think replacing the Main board will get you out of standby.
