    I have a Daewoo model DTQ-20u9sc built August '05, serial # BGR533Ye1011766. I believe it failed from a lightning strike. It is totally dead, unresponsive. I opened the unit and saw that the fuse on the board was blown and replaced it, but still nothing. Your thoughts?

If you know something about TV repair then you can try to fix it yourself. In which case, you can get help here by giving the exact make and model of the TV; if on the other hand you know next to nothing, then the safest route is to take it down to your nearest TV repair shop. Good luck.

No power blowing fuses


Hi,
    According to the symptom if the TV blowing fuse repeatedly then there must be a short circuit in the power supply, Check the PTC it must be short and blowing fuse due to it. 
    Hope this will fix your problem.
    Thanks.

TV won't turn on


take the back off the tv and inspect the glass fuse off the ac power cord, it will probably be black and open, this is a common problem, it blows because the degaussing circuit works too slow, the original fuse is an 6.3 amp fuse, you need to replace it with a 6.3 amp slow blow or a 7 or 8 amp fuse to keep it from blowing, if you put an original 6.3 amp fast blow fuse in it, it will work for a while, but will blow again someday.

If the fuse blows again after replacing it, there's a shorted diode, bridge rectifier, capacitor or transistor in the power supply.

I had a power outage and now the tv will not power on. This is for a 55" Mitsubishi WS-55511. no green blinking lights.


Hi,

You may have a blown fuse. Unplug the TV and remove the back. Look for a small fuse near where the power cord goes in.
If it is blown that may be the problem.
Use a magnifying glass to read the AMP rating.
replace the fuse and plug it in. If the fuse blows again you need expert repair services.

If the fuse doesn't blow then try to turn it on.
If it turns on then check the operation of the TV.

If the fuse blows again or the TV won't work correctly then you need expert repair service to fix your TV.

You may be able to have your household insurance pay if it is damaged by lightening or a power surge.

Blown fuse


Most likely there was a power event (surge, brownout, ect) that caused the power supply to fail in the TV causing the fuse to blow. you will need to have someone come and look at the unit and give you an estimate. If you keep putting fuses in and blowing them you could actually be causing more damage.

TV Blows internal fuse


You will have to find the source of a major short in your power supply.Since it's a 5A i assume i imagine that's where the short is.
