Question about Samsung Televison & Video

1 Answer

I have a problem with the power supply board with my TV (Samsung LN46A750). I had a fuse blown and tried to replace it (with a like fuse, of course). Replacing that fuse and attaching the power cord let to not only the new fuse blowing again, but also one of the disc shaped capacitors on the board (it let out a loud spark!). Obvioulsy I need a new board. My question is; is this something I have to look forward to every 2-3 years or was this my punishment for not having my TV surge protected? I appreciate any and all feedback! Thank you to whoever lends assistance!

Power supply board have power surge parts,but not totally dead,it just giving to much power some where,that why it keep killing ur fuse.This problems,u must have great electronic skills to track it down.Tries websites like Shopjimmy.com,Ebay.com to buy a refurbish power supply board for the replacement.Power surges are rarely happen,but the surge protector will stop massive power will go the protector when it happen instead all the power will go to the tv itself.

Samsung tv CS-29M16MG fuse always blown


Fault with the main power supply regulator board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts.

It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time.

It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.

Tv starts turning on then turns off several times. never fully boots up.


Most likely failed capacitors in the power supply. I recently had the same problem with my 26 month old Samsung LN46A750. Samsung paid for the installation of an upgraded power supply board.

Tv turning on and off by itself - never fully turning on


Most likely failed capacitors in the power supply. I am currently having the same problem with my 26 month old LN46A750. Samsung has agreed to fix this as an out of warranty "courtesy repair".
