Question about Televison & Video

Advent HT3251A tv. The power indicator does not light up. Guess the stand-by power supply is bad but have no idea where it is located on the pcb so I can check components. Can't find a schematic.

Picture lools like hour glass


This sounds like an effect called pincushion. Look under your tv options for an option called pincushion and try adjusting that.

What is the circuit designation of the part in question? It should be marked on the board as Rxxx or FBxxx. Post that here. That should allow us to identify what it is at the very least.

Clicking power supply? wont turn on


I had the Same issue. on a 50PF9431D/37 set. Many Plasma Set's use a LJ44-00118A PS-505-PH Power supply from Samsun. Know 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 conections. http://www.shopjimmy.com/power-supply-unit-lj44-00118a-from-philips-50mf231d-40.htm. Link to a photo of the PCB. Make a note of the location of all cable connections then unplug them all. Un-install PCB, Check a 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. 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.

Advent HT2751A display no good until after 1-2 hour warmup - maybe


After 3 years, I finally decided to open up the TV and do some troubleshooting. Found out the problem, It was a blown capacitor Location C554 Capacitor value is 2200uF 16V - costs about a dollar to replace yourself and the TV works brand new.
