When I try to plug the tv into the surge protector it sparks before I even get it half way in. It also blows the fuse on the board at the same time. What can be the problem?

You have a shorted transistor, regulator IC, or component. Do not continue to plug the TV into the outlet - it may cause a fire. Have a repair technician isolate the problem.

This TV will not turn on. It went out during a storm but the other appliances plugged into the surge protector were ok. I have tried plugging it into other outlets- still nothing


Fault in 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. 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 won't turn on


there is a surge protector on the main power board this has probably blown. or the main power board fuse or plug fuse. check them one by one. there even may be a secondary fuse in the tv around 3amp witch can blow. it will have red and black lines on it or orange that is the rating of the fuse. surge protector is like a battery shap round with 2 prongs onto the board.

There should be a surge release button on the surge protector to bring the protector back to normal (should be red in color) Some surge protection devices have this option so just check if your s has it. If that is not the case than I think that you might have blown a fuse in your TV.Might just have to open it up and change the fuse within with the same ratings, but please be careful because do have high voltages so get an experienced technician to do this for you.
Good Luck.

If you have no power light on TV ,then you must have a blowed Fuse on the power supply board.
Check Fuse and check board for Bad Capacitors they will be vented or swollen on Top.

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.

We had a power surge in our living room while the TV was on. It was also plugged into a surge protector, however, everything else turned back on but the TV. There is no power going into it at all, as if...


Sounds like it might have blew a fuse on the AC input to the power supply, have to remove the back and look for a fuse near where the AC wires go from the plug on the tv. If the fuse is good
the power supply board will have to be checked or replaced..Next time consider buying a surge
protector that starts clamping at a lower voltage. Panamax brands usually start going to work
at 150v rms, where most others start at 330v rms..

Check the main fuse in the power supply, the TV also has small surge protection devices (MOVs) installed after the fuse, any surges the come along and big enough will cause the main AC fuse to blow. When you surge protector, EVERY connections must go through the surge protector, for example, the AC cord of the TV is connected to the surge protector, the cable connection did not go through the surge protection, the surge then can get to the TV through the cables.
