Just replaced capasiters on tv. now it starts properly but then turns off right after.

It may have a bulb inside that is burnt or possibly it is a capasiter that is out, although it is probably a capasiter.Capasiters can be changed,look on youtube on how to do this

I had same problem, i just replaced the power capasiters on the board an solved it...look for mushroom heads or bottoms on them an swap them out an it should be it. And if thats it then buy the higher temp capasiters so it wont happen again..

pull up the tv and check the power suply for bad capasiter that might me your problem ok

pls. check power coad is likage or luse canaction in plugh
if ok then problum is inside of tv so pls. cheked in pcb.....
1st : SMPS output voltage and 5v /12v/ 24v /135v dc filter capaciter cheked and replace 470/16v /1000/35v / 220/450v if any capaciter likage or sort * first cheked dyode.
2nd : EHT output line capasiter or dyode checked 4.7/250v /100/160v
and line coil or 1ohm register cheked
3rd : DT (driver transfermor ) and with cancting spear dry.
note: pls descanect tv with DVR and cheked tv set is turn on atlist 10min. minimum with any ather product (DVD , GAME BOX ,CABEL CANACTION) if is ok. then problum in DVB setup box .

Try to replace the capacitor. It this will not work, measure the draw current of the compressor. The lock rotor current is usually given on the plate attached to it. If the current is within or beyond the plate figure, its time to replace the compressor.

it seems like a burned out capasitator, get it repaired.

The Problem is with the Capasiters in the power supply bord a total of 9 caps have to be replaced the power supply bord is the one on the right side of the tv in the back where the power cable enters the caps values are 35 volt 1000uf x2 35 volt 470uf x3 16 volt 1000uf x3 and 16 volt 470uf x1 after replaceing thses caps the tv will work like new... i hope this helps.

The capacitor you are looking for is on the Deflection Board on bottom is 2 boards on left is Deflection board on right side is SSB board it has the turners on it.cp150,cp114,cp120 these are the 3 capacitors to replace if cp150 is puffed up on top.

it sounds like a couple of you capasiters went out they are located on each corner of the tv if they are popped up then they need replaced as they are supposed to be flat on top

I posted photos and a description of my solution for this problem here: http://www.flickr.com/photos/geegee123/sets/72157607269121264/ There's another thread on FixYa dealing with this same issue that has a variety of solutions as well.
