I bet you $120.00 you did not have a 1000VA UPS on it. If I was right, you can pay me now, and I can send you one.

You need a new TV.....or it will cost you $150.00 to fix.

The thinner they are the faster they blow...by the way they have a computer in there.

My 73'' mitsubishi model #wd-73738. Is flickering.


Hi!
That's a clear indication that you have a bad power supply in your TV.
If you know how to DiY...I suggest you open your TV. Locate the power supply section, it is where the end of the power plug is connected. Replace all blown or bulge or leaked capacitors with same value. That will fix your TV problem.
The hardest part is to disassembling your TV cover, cause you will need to pry off the snap in lock at the edge of your TV.

Power supply board should look like this. Examine the capacitors in the board

After replacing blown capacitors...it should work again.
caps%281%29%281%29.jpg

Things you will need.
1. A plastic flat end screw or any object with flat ends....to fry off the cover
2. Soldering iron.
3. Soldering lead
4. Soldering pump.
5. Flat and Philip Screw
6. Replacement capacitors (of same value with the blown one) that you can buy to any electronics store.

Or try replace light engine..if the above solution won't work..

LG 37LG30 model won't come on after power outage. Red light is on but we can't get the TV to turn on.


Good day!!!


Red light it means that you have power on the TV but the system is stand by due to faulty parts...

Normally if your TV is on standby mode every time you attempt to power it ON...That problem are 2 causes its either power supply board or main board..

So lets find out...Just follow this procedure to determine what are the faulty parts..


1. Open the back cover.
2. Check the power supply output...It should have 5vdc for the main board..12vdc or 16vdc for the audio and 24vdc for the back-light inverter..
3. If those 3 voltage supplies have encountered voltage drop...The problem could be on power supply board..
4. If the power supply output is normal..The problem could be on the main board...
5. If the problem is power supply you should check if the capacitors are bulged on the top and try to replaced it..If you can't do that you can purchased new power supply board..
6. If the problem is on main board there is no D.I.Y repair on that so you need to buy a new main board that fits to your TV..

If you have any clarification or query..Just add a comment..

Hope this solution will be helpful..

Thanks for using fixya...

We have a 46 inch sharp tv model number 46SB54U won't turn on. The green timer light is flashing. We just replaced the power supply board thinking that was the problem. TV still won't turn on...


Hello,

Your power supply board is dead, u know basic electronics' and soldering? Most of the times, the power supply board just have dead leakages gases capacitors.These capacitors always bulges up on it top,or puff up on it top.Replaced these gases leakages capacitors will get your TV power stable,and work again.Or tries websites like Shopjimmy.com,Ebay.com to buy a whole refurbish power supply board for the replacement.

I hope this will helpout ......

I have a belkin N1 router V4000 We had a power outage and not it won't turn on again. This happened once before and I thought it was dead but somehow I revived it but now I can't remember...


If you have a volt meater check the power supply to see if it is sending the correct power. If you get a rating more that 5 volts above or below the rated voltage you have a busted power supply. If it is above 5 volts the router is most likely dead.

If you don't have one try to locate another 12v (or whatever its voltage is) power supply.

TV suddenly shut off - and now won't turn back on. Screen went totally black. When you try to turn it back on, screen stays dark, and tv has a humming sound that wouldn't shut off until unplugged. Not...


Did this unit fail after a power outage or passing storm? If so could be lost of component in the low voltage power supply circuit or degausing relay circuit. I would strongly suggest you seek help from a qualified repair center. Don not attempt to repair yourself...to dangerous.

The power outage went out yesterday and my tv wont turn on


Hi,
Most likely it is capacitors on the dm board that have gone bad. This is a fairly common problem and has been addressed on fixya many times. If you know someone who is good with soldering and technically incline or even an honest electronics guy then the repair is quite cheap. If you have any other questions please let me know. if its not the capacitors on the DM supply then its a problem with the whole DM assembly that part usually is around 300$. So you may want to consider purchasing a new tv. Trying the 7 caps on the dm supply board shouldn't cost much if it takes anything more then that. I would sell the tv on craigslist or ebay and recoup as much as you can towards your next tv.
thank you,

PC won't start up


Check for power on the A/C outlet. Maybe the circuit breakers were tripped. If there is power, then the power supply installed on the computer might be surged. Replace power supply if thats the case. Normally, there's a button that says 'power' or an image of a lightbulb... you need not use the remote.

ILO 2706 TV WONT TURN ON


This TV might have been affected by the power outage even if it was not ON at that moment. There is a standby voltage still present even when OFF and connected to the AC line.
There might be different failures on this TV:
1. The power supply might be defective after the power outage.
2. The main board could also be defective since the power supplies for today's TVs are not well regulated and once the voltage getting to the power supply increases, the standby voltage voltage will also increase damaging voltage sensitive components like the microprocessor or memory circuitry.

Let me know if you require further assistance.
