SOURCE: My LC-46LE620ut blew out R9137 on power supply board. Replaced resistor and then another component shorted out.Will replacing power supply board fix this problem? Where can I get a replacement power

Without seeing the board or the schematics, I can't say that replacing the power supply will fix your problem. There could be a short external to the power supply that is causing your problem. You can buy replacement parts from
Shopjimmy.com or Ebay.com
There are a few decent parts sellers on Ebay who actually offer warranties

Sharp LC-50LE442U does not turn on. RED standby LED is lit, when I try to turn it on, the LED turns green but screen stays black. LED then stays green, won't go back to red when turning off.


You cannot tell if capacitors are bad just by looking at them. they need to have a meter called an ESR meter to test them, I can tell you with almost certainty that it is a capacitor in the power supply that has failed. The whole board is Sharp 9JY0950CTN02000 Power Supply Board (09-50CTN020-00) LC-50LE440U LC-50LE442U

I have a Aquos LC-37GP1U new out of box. Have the blinking light issue. Power on for 2 seconds and then shut off. Replaced the power supply board as it was cracked. Still didn't help. Should I be...


Hi,


You have to check if the replacement power supply board is the same part no. as the original one, it is printed on the board itself.


I don't think that the fault came from defective electrolytic capacitor because like what you have said, the unit is new out of the box and you've already replaced the power supply board which is most of faulty electrolytic capacitor came from that board.


You've mentioned also that the original power supply board has cracked, I've suspected that the main board also has been damaged because the blinking led light error codes will be encountered if the power supply board or main board gone to malfunction. If you've confirm that the power supply board is the same part no. like the original one, then I would advice you to replaced the main board.


Please let me know if you need further assistance.


Have a great day!

TV Sharp Aquos LC-32D44E/S doesn't come on Status light turns green for 10 seconds then turns red but no picture or sound.


Good day to you and welcome to fixya..

That problem is usually have 2 causes..Its either power supply board or main board..

Please take this steps on how to determine the problem:
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..

You have a better chances if you have failing capacitors on the power supply board..

Please watch this videos about capacitors..








Hope this solution will be helpful..

Thanks for using fixya...

Blinking led


Free diagrams unlikely to be available take the board's out and check for blown capacitors following good antistatic procedures and decide from there
Or find a good independent repair specialist to do the work and set your self a budget

My Sharp Aquos LCD TV LC-40C37U will not power up. The green power lamp at the bottom right is blinking. We had a power surge last night, I even measured 180V on the power outlet. Is my TV now damaged?


Good day sir/maam, chances are, yes or no, yes, the surge do has the ability to damage your TV, but no, modern TVs are autovolt (it can work from 90v-240v) so check the manual or back panel to confirm. The most deadly part of the surge is it can hit more than 500v at a split of a second, damaging your TV's switching power supply. The TV's power supply is bad. it cannot produce the proper voltage to power your TV. thats why its on standby. Bring it to your dealer for proper advice on the status of your TV.
