My set is about 4 years old and does not function. There is no picture. I have checked the fuse on the power supply board (BN96-00249A) and it is fine. Is there a way to check the various outputs to ensure the PS is at fault before I order a replacement PS board? Regards Tim
You can get the schematics for the bn96 00249a smps here in pdf format. http://www.wimtv.be/techniforum/files/ps42p3sx_ch._d58a.pdf
Replaced C523, and C524 on my set and it's now working. Symptoms were no picture and no power coming off the power supply board, except for Vs. Other outputs were low or 0.
Rddixon,-- I tried that site, and no go. says done, and just gives me a white screen, can you email it to me? same username @yahoo.com. that be great!. -- Anyone know if replacing this this will fix a 5 blinking red light issue? thanks.
I repaired mine today. Yes you can check various voltages. The voltages are listed in the tv. If you open it up in the back, inside there's a sticker on the back of the panel which is a thick metal. It lists the voltages on it that the voltages on the power board should be close to.

Same issue. I checked and found that I had no power out on CN804, all fuses were good. Upon closer inspection I found 2 burnt solder marks on the back of the board for C523, and C524. It also appeared that C524 had split and was oozing a hard grey substance (solid not wet) as if the component had burst. These components were brown in color and mounted at the top middle of PCB.
I am going to order the board and will let ya know.
