If you see a brief spark at the outlet when plugging in the power cord, this may be absolutely normal. It is the surge that happens when a modern switching supply is plugged in and that big capacitor charges up. If no fuses blow, and the spark occurs every time it is very likely normal. Some poorly designed supplies give a real arc-weld when plugged in, most just crackle a bit.
To the original problem, most newer sets have a small amount of power that is supplied to a microprocessor control board. If this small supply is out for some reason the set won't turn on.

Hi there!

Where you saw the Arcing, check closer to see wether the components are not loose on the board. You may only have to resolder the joints and problem solved. If the arcing takes place towards the tube, then you have a more serious fault. Thus involving High Tension, so I would not advise trying to repair that area if you are not familiar with TV repairs. Please unplug set before commencing any work. Regards and good luck, JUS004

Toshiba 32c100u dead; power supply board replaced but still nothing


Have you checked whether mains power reaches the power board? Check it first. If yes, the power board you purchased newly should be checked.

I have aVizio VX42L HDTV10A. was watching a show when we heard a loud pop.Then all went dark. Would not turn back on. I took off the back cover and found the ceramic fuse was blown on the board # DPS-283AP...


This means you have a dead short, It is probably a Diode in the power supply area, but without testing board you don't know. If you know basic electronics, i would say check all diodes in power supply and look hard for something burnt and replace that also. Or just replace power board, check shopjimmy.com

MY VP42HDTV WILL NOT DO NOTHING WHEN I PLUG IT IN WHAT COULD IT BE.


Hi if you plug it in at the mains and switch it on and you get nothing not even the standby light then this points to either a fuse been blown so check the fuse in the plug failing that it will mean getting a new power board fitted, now if the telly is more than say 2 years old i would say its not worth getting fixed as the chances are you will replace the power board and then you will start having problems with the inverter, soyou could end up throwing money down the drain.

if its less than 2 years old and its totally dead check the fuse in the plug change it anyway and then give it a try but if its still totally dead then this points to either the fuse been blown in the telly this is a little clear glass fuse located where the mains cable plugs into the main power board, if this fuse is not blown also then the whole power board will need replacing.

let me know how you get on or if you need further assistance ok

plz rate this solution as i have a whole page of unrated posts, thanks

Heard a pop then screen went blank. Now TV wont turn on.


Sounds like your fuse.

If not the fuse in your plug, then the internal fuse in the TV. to get too this you need to open the TV by taking off the back plastic panel and look at the fuse.

the fuse is the glass tube on the board, will no doubt be near where the power cord connects to the TV. and are easy to replace with another fuse. you will know soon as you open it if its blown as the little glass tube will be blackened or the little wire inside the tube will be missing or severed.

Fuses in TVs are actually designed to blow over time with ware (usually to last a bit longer then the warranty time frame) so after the cover has ended the TV can go in for repair work at extra cost. Its a little known fact.

I have an emerson tv and it will not power on at all. The little light wont even come on.


Solution 1 was just step 1. If the outlet gets power and the fuse or circuit breaker is ok, then U have a bad tv. That seems to be the most common problems with lcd's when they go bad. They either give the blinking light and not coming on, or they go completely dead. Most common causes are a bad power supply or a bad board/PCB/Circuit board.

LG RP TV wents fizz, now no picture or sound


The flyback transformer or the "spitter" has a problem and should be replaced. Figure on about $100 for the part(s) and the local labor charge as the cost. Call around. This is a simple diagnosis as the insulation has broken down in the part.
