SOURCE: INSIGNIA LCD won't turn on

replace 2 condensers in the power supply with greater voltage ones.original are 1000uf 35volt...use 1000uf 65volt...99cents each
power circuit is made to fail with typical tv industry tactics...the warranty is reflected by the life of their condensors (capacitors) average life is 2000 hours..
easy...huh
if your a smoker...you must clean the button cover as they get stuck on with your stupid tobacco residue. 75% of all LCD tv's that smokers own fail this way...

SOURCE: Hi. My Philips flat TV will not show any picture

I had the Same issue. on a 50PF9431D/37 set. Many Plasma Set's use a LJ44-00118A PS-505-PH Power supply from Samsung. Known to have this common problem. If you can, or have a friend that can Solder components?. Unplug your set remove the back panel & locate your power supply. It will be the PCB in the center of the set just above the Video/Audio connections. http://www.shopjimmy.com/power-supply-unit-lj44-00118a-from-philips-50mf231d-40.htm. Is a Link to a photo of the PCB. Make a note of the locations of all cable connections then unplug them all. Un-install PCB, Check all Fuse first. I believe their is 5 or 6 of them on the PCB. Then replace the two 3300uf 10v 105C Radial capacitors at C8060 & C8059. Look to see if the Caps are deformed and or split at the top. The location of the caps are in the Lower bottom edge of the PCB. A local shop may Carrie them if not, digi-key has them. Part # http://search.digikey.com/scripts/DkSearch/dksus.dll?Detail&name=493-1754-ND. Total cost was $7 with S/H.

SOURCE: tv wont turn on

Hello Charliebigwh, hi technically your monitor's power supply has a problem, this is either your switching regulator does not work or there is a short in that section, If you want to do it your self, need to replace all large value, and or high voltage capacitors(especially the capacitors with its top is bubbly), need also to replace the switching IC, and power transistor.

Have it checked by a technician if you cannot do the work.

My tv is keep turning itself on and off and my remote has randomly stopped working, ive had the plug out the wall the past 6 hours nd no joy, any ideas? I've put new batteries in the remote 2


Sounds like a power board issue? Dry joints on the main board? Capacitors may have issues.? I would not go opening up the TV if you are not aware of the potential dangers.

If you have power to the standby light but no life beyond that you could be looking at a main tuner pcb: Link attached:

Contact any service technician. The fuse can be located at its main power supply regulator board itself. If you wish to get some details; check the site linked here. Viewing it in "Mosaic" will make surf easy.
