Question about Sylvania 6626LCT 26 in. LCD Television

2 Answers

Fuse Blowing My wife's cat has chewed a few light slits on the power cord and it no longer works. I opened the tv and noticed that the fuse that is next to the power cord wires was blown. I bought a pack of fuses and replaced one thinking that maybe the fuse was just bad. When I pluged the unit back in the fuse blew again. Is this a problem with the cord or may there be something internal that went wrong? Also, if it is the cord is it possible to just open the cord, re-attach bad wires (if necessary) and tape the cord back up? My warranty won't cover this and people seem to want a lot to repair this problem.

Re: Fuse Blowing

For the fuse to blow it must be receiving power,this places the fault beyond the fuse,without knowing what type of tv we are dealing with i can only assume a short circuit on the power supply board.

Re: Fuse Blowing

A blown fuse is usually caused by a shorted regulator or a bridge rectifier circuit. Either way it is a problem in the primary power supply. A bad cord won't blow the fuse in the set, it will blow a circuit breaker in the house. A servicer usually would normally cover the inside of the set with a "few light slits in the AC cord". Hope this helps

Our LG TV will not power on. No light, no sound, nothing. How can we check the fuse on the power supply? Or could it be the power cord?

Hi Dfhamilton,
Damages due to lightening surge can go to any extent in a tv set. If you can, please open the back cover and check the fuse. Replace with the same rating one if you find it blown. Switch on the set. If it works, enjoy watching. If it blows again, please consult some TV tech.
Good Luck.

Hi my tv not turning on or light up. I check the fuse but it's ok

Have you tried plugging something else into same outlet to be sure wall outlet is still functioning. If that isn't the problem depending on type of TV set there are internal fuses that can only be changed by dealers. Also check your cord to be sure there isn't any wear marks or chew marks from a pet that may have chewed on it

Wharfedale LCD2710HDAF no power to tv, checked cable and changed fuse a few times, new power lead? or is this a common problem?


The power cord must be checked using a multimeter. The test is done reading impedance (ohms) between plug's prongs and contacts to TV power board.

If the power cord is OK and there is no power, then the problem is the power board inside the TV.

My VEA 42 inch TV is no longer getting power. Is it just a fuse or do I need to replace something els.


If there's no led light at the front panel of your unit, this is an indication that the power supply board is not working.
Please check the instructions below.
If you're unit is not under warranty period(if so, avail it because the manufacturer will fix it for free) you may open the back cover of it.

1.Power cord - check the cord it might be opened (no continuity).This is due to frequent bending,pulling. 2. Power switch - check for dry joints, open contact. 3.Check the internal fuse- sometimes the fuse fail because of the power surge, replacing with new one will cure the problem, If this is the case I would advice you to use surge protector/AVR (Automatic Voltage Regulator). However if the fuse blew again this is an indication that you have a shorted parts in the power supply, you may visit the link for more info. If no reaction and still the unit didn't power up then you have an open parts on the power supply.
4.If you see that the fuse is intact , don't attempt to touch anything because there some fatalcomponents stored electricity enough to hurt you with a simple mistake only. I would advice you to look for a professional to troubleshoot the power supply.

Hope I helped you.
Have a nice day!
Thanks for using Fixya.

Samsung LN40A530P1F LCD TV keeps blowing main power fuse when i turn set on it blows right away i have replaced fuse many times. Also when back was off i noticed a arcing as fuse blows at a component just...
If a fuse blows like that there is a major problem, inside. I suspect that what your are seeing is the inrush thermistor, and they exhibit this under great load. I would explect that this fault maybe in the actual PSU. Due to the lack of service manual support, i would get a quote for repair from an authorised service center.

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.

Tv did not turn on

Look at the power supply to see if anyhting burnt, fuse, bad capacitors. I doubt that the power cord is bad, the same size fuse should be used as the original one.

42" LCD HD TV keeps blowing fuses.

A ceramic fuse stands up to heat better than a non-ceramic fuse. I'm no pro, but it sounds like your power inverter board maybe bad. There are replacements out there. Good luck

No power on my astar LTV27HBG

I had this issue, I tore the tv apart and found that my power switch had gone bad. I just traced the power using a multimeter. There was no fuse it the power line, and no reset button that I noticed.

Sounds like the power surge may have blown the fuse in the TV. You can replace the fuse and see if that works. If not, more damage to the power supply unit may have occurred.
