Re: EWF2703 27" TV --won't turn on
A complete circuit board is available BUT would cost you more then a new set. These sets now a days are repaired down to the componet level and these sets have no user replaceable parts. If you have a capacitor checker then maybe you can find on that goes bad in these . there in the sweep supply or in the standby power supply, but if your not a trained electronic tech you should not be experimenting inside this thing. 2 to 3 years is about normal with these things. You can get one for about 100 or so if you looked around. it would probably cost you 125 or so to have a pro fix it. GGood Luck

you must measure the power input with VOM, test for loose wires, or corroded and fix it. Otherwise you must sure if the controller is o.k,use testbench for test outside from the vehicle and see what happen. God bless you
tried with other ac outlet doesn't work?. if still won't turn on, at this time you will need to remove the rear cover to gain access the internal part. since your tv doesn't have any power indicator, the first place to be checked will be the power supply board this is where the power connector cord is connected. now look for a blown fuse replaced with the same rating. but take note before you replaced the bad fuse you must need to have component testing in the power supply board which the cause of blown of the fuse. like shorted bridge diode, open resistance and defective mosfet or bad regulator ic.at this time you will need a device called digital tester to check weather the parts need replacement.hope this can help good luck.
see this causes and fix it. God bless you If the furnace won't run, check the electrical service panel
for a blown fuse or tripped breaker. Also make sure the power switch on
or near the furnace is turned on. Check the unit for a reset button and
try it. Some units have a built-in breaker or fuse panel. However you can have a missing 1 phase , test with the VOM, for to measure voltage. Or motor need repair for winding trouble,bearing.If you do not have enough experience call some electrician. God bless you
hello! it seems, like the problem of your TV is the power supply module, particularly 12v power supply I.C. chip.STRW6735 or similar. I've replaced few lately with similar problem TV. It might have a few bad electrolytic capacitors on the board, as well. Solution: if you are possess electronics technician skills and have all the necessary equipment and parts , you may do the job yourself. Otherwise, look for replacement power supply board, preferably at used boards distributors(shopjimmy.com or similar). I won't recommend to buy used on e-bay, unless it has been rebuilt. Or, remove the board and take it to local TV repair shop for rebuilding. This way you may save a few bucks. Good luck, Alex.
Power could be off- - Check the voltage at the outlet with the VOM.
Timer or thermostat could be bad -- Follow same tests as listed above.
Terminal block could be bad -- Use the VOM to check for voltage at the
terminal block. Be very careful here, as the power needs to be on for
this test. If you don't feel comfortable, call an experienced
Start switch could be bad -- Set the VOM
to RX1 and remove one of the leads to the switch. Clip the probes to
the switch's terminals. The reading should be infinity. Press the start
button and the reading should change to zero. If not, the start switch
of course, are not everything that can go wrong with your dryer, but
only the most common problems. When removing parts for replacement, I
find keeping a notebook nearby to take notes on which wire goes where,
to be a valuable assistant. Of course, when you take your faulty part
to the appliance parts shop, make sure to have the make and model
number for your dryer, just in case they need it. With that said, good
luck and hopefully your dryer will be sound for a few more years. please rate or vote on these solution on how helpful.
You will need to remove the back of the TV. Don't worry, it's not that bad.
There are 4 screws across the top, one on each side, one right next to
where the power cord goes into the back of the case, and the two more
by all of the video connections **These are the most important to
remove because they attach the main board to the back of the case.
Once you have remove the screws then the entire back of the set will
slide off. If you look where the power cord attaches to the board you
will see a small fuse. This is a 6.3 Amp 125 volt fuse. You can replace
it with a 6.3 Amp 250 volt fuse from your local Radio Shack. A four
pack costs between $3 and $5.
Make sure that you check that it works before putting it all back
together. Check for any loose connection cables while you're back
there. I found a few when I did this.
