I replaced my power supply on my Tv. The new part I got blew out on me.


Did you replaced the power supply as card basis; or, repaired it by replacing any capacitors at it. If you have replaced the capacitors only, the polarity of the capacitor you've replaced might be reversed. Capacitors have both +Ve and --Ve polarities, and should match with the markings at the board; otherwise it will burst when you power it up.

Potentially so, however I would get the TV fully checked over by a professional if it has been subject to a surge. If a component further down the line caused the initial surge replacing the blown cap will only result in another bang as soon as you plug it in.

AFTER POWER OUTAGE IT IS DEAD


Voltage spike likely blew across the dielectric of several electrolytic capacitors. The internal fuse may or may not have survived. If it did not- replace it once and see if it is as simple as that, although you are likely looking something more.

If you want to try to salvage it, recap all electrolytics and tantalums. with new high ripple current types for the electrolytics.

My samsung ln52a650 blew a fuse during normal operation. one second it worked the next... nothing. popped her open and couldn't find any damage/arc/flash.... exploded parts. i hear this is a common...


U have all the tools and understanding basic electronic and also can do basic soldering?Yes.The tv power supply board,that the board,where the power a/c cord plug into it.Check the whole tv power supply board carefully for dying capacitors components parts.It is usally have bulges or puffing up capacitors parts indication of components capacitors parts are dying and needed replacement.Replacement for those new capacitors component parts with the same Micro ferit and the voltages of those new components capacitors parts in a higher voltages like 5 or 10 voltages higher than the old components capacitors parts u are replacing for a better heat resistance for the tv operation of the tv power supply board for later on tv use.Or tries websites like Shopjimmy.com,Ebay.com to buy a whole refurbish power supply board for the replacement.

My philips 14 inch tv is not working the capacitor 400v was explode and i change it i clean all the chemicals that were on the borde abd the fuse is new what can i do?


I would blanket change the power supply if it isn't working. The electrolyte is conductive and will do an awful lot of damage.
By your description "400v" I presume you mean the main smoothing capacitor, in which case the power supply has been drawing excessive current to make the capacitor leak so I would look next at the line output section.
Hope that helps.

Panasonic TH42PX60B blew fuse in plug, replaced fuse now just flashes 10 times will not start


Hello,

Your power supply board is dead, u know basic electronics’ and soldering? Most of the times, the power supply board just have dead leakages gases capacitors.These capacitors always bulges up on it top,or puff up on it top.Replaced these gases leakages capacitors will get your TV power stable,and work again.Or tries websites like Shopjimmy.com,Ebay.com to buy a whole refurbish power supply board for the replacement.

Take care......

My pwoer supply blew up as well part number HGP 180-p240JIFE


Ladies and Gentlemen,

Relative to Olevia TV Power Supply Problems Solution provided by: kb8tez Matt, the problem he had was Electrolytic Capacitor CS21. Upon careful examination of the Power Supply Circuit Board I find that CS21 is in parallel with CS22. Simply replacing BOTH Capacitors makes for a more permanent fix. Radio Shack P/N 272-1032 1000UF 35V Capacitors @ $1.59 each plus tax makes a very inexpensive repair. Apparently the same power supply circuit board is common to many different Olevia Models.

TV power supply problem


.01 mf 2000 volt. in flyback circuit .it is a timing capacitor. the red high voltage block is bad and that took out the capacitor. also check the horizontal output transistor...it is probably shorted.
