They are not BULBS by any stretch of the imagination. They are CRTs (Cathode Ray Tubes, also known as "picture tubes," and each of them are small television screens, in essence), which are optically enlarged for projection onto the back of the front screen. Don't be tempted to think that you will merely be able to replace a "bulb" and have everything work!
Although you will be able to replace all of the components on the PC board if necessary (they all remain available), and may be able to fix the coolant leak that caused the failure, the CRT may have overheated. Considering the advanced age of the television, the tubes are likely already somewhat burned-in. Best to just dispose of the set.

Same problem. TV worked night before and then would turn on but no picture or sound. Power and OPC lights blinking. I couldn't change the channel or get to the menu.
I disconnected the coaxial cable and the power for a few minutes and then plugged it back in (electric) but left the cable off. I got a message that it couldn;t get a signal. At that point I was able to change the channels. I plugged the cable line back in and everything worked fine... Good luck!!!

I know what you mean. :(
I couldn't get mine to work with my Emerson TV. No codes worked.
You may have a chance with yours. Try this link here to get and program the codes:
Then if does control the TV, hopefully the input button on the remote will work.

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.
