Lct2662 power supply

Our internal power board's voltage has dropped out and the TV no longer turns on. I have a back ground in electronics so I took the volt meter to the various dc outputs and noticed a surging voltage (up and down) - I also noticed the caps had swolen tops.
I replaced all the caps and some of the IC's haphazardly but to no avail.
I would rather replace the damn thing and move on with my life but no one online seems to carry the internal power board.

Now what?

Call 800-726-4405 - But the part may not be available - request an exchange through the manufacturer. By law the manufacturer must provide parts for 5 years.

If the power supply outputs are good! Then I would say the back light inverter is bad! If the screen stays black and does not come on.

Well, take the plug that goes to the inverter board out which has the 12v on it. Check the 12v again at the power supply. If 12v is low you can possibly have 2 caps bad, the values should be about 1000uf/35v or there abouts. They set close to the plug. If that doesn't work then replace the Power Supply because there are no service manuals for lcd p/s. plus nearly impossible to locate individual ic's. Try Shop for the P/S.

Turn on my tv and it goes right back off

tried to disconnect all the output connectors from the power supply board, then make a voltage checking if output voltage is available. if no output dc voltages or drop you have bad power supply board.

When i turn off tv it wont go back on for hours

The most likely issue is your power supply is failing. Most likely issue that would cause this problem is bad capacitors on the power supply.
What happens in the above situation is:
After the Tv has been off for some time the electronics and capacitors are cool and supply the correct voltage so the TV turns on.
After using the TV the electronics heat up and the material in the capacitors expands causing the power supply to supply incorrect voltage. With the TV the power is flowing and is close enough to the correct values for the TV to stay on, after being shut off the TV will not turn back on because correct voltage is not present until the components cool down and the voltage at power on no longer engages the protection circuit.

Hi, My TV has been turning off by itself and

Good day!!!!

If your TV turn ON/OFF itself without sounds..The possible problems are voltage drop on power supply,overheat/overload,loose/cold solder of power supply or bad T-con board..

If you already inspected all capacitors on the power supply and all looks fine but it doesn't mean that your power supply board works fine because sometimes bad capacitors not look like bulged or looks fine visually but the value change its either lower/higher capacitance value.In that case you need to use capacitance meter to find bad caps..But before we do that,I have a procedure to minimize/eliminate troubleshooting.In this procedure you need a multimeter tester to perform voltage data check..

In this procedure we can determine where the fault came from..

This are the steps:
  1. Open the back cover.
  2. Look at the power supply board (it is usually connected directly to power cord).
3. Find the 3 long connectors near the aluminum heat sink.Those connectors having voltage marks on each pins so you can easily determine where did you get the voltage..

4. Point the black test probe to GND (ground) and the other probe (red) to 5vdc,12vdc/15vdc,24vdc..Let me know if you find any voltage drop or voltage lost..

5. If all voltages are works fine..The possible problem is on T-con/logic board or main board..But in that case the common problems is on T-con board I found it online $34..

Hope it helps..Just keep on touch to fix your TV and works fine again..

TV had no picture first and then no sound. I have unpugged TV and still nothing happens. There is a blinking red light on that can be seen from rear of TV ( 1 blink on and off). Thanks for your help.

Good day!

Please follow this procedure to fix your problem:
  1. Open the cover of your TV.Remove all screws at the back.
  2. Next,power ON the TV and check the output voltage of power supply using voltmeter.
  3. It should have not less than 5vdc for system board,12vdc for sounds and 24vdc for inverter board.If the 3 supplies are got a voltage drop your power supply had problem.For example if you check the 5vdc then the reading is 4.50vdc only.
  4. If you have voltage drop,check some leak/bulge on top capacitor on power supply.replace it using soldering iron and soldering pump.
  5. When the power supply looks like OK,no voltage drop and no leak/bulge on top capacitor.The problem is your system board or main board.There's no easy remedy for that.You have to replace the whole system board.
A Power supply is like this..(It is not actually look like yours but it was just for your Idea)

Please let me rate and testify by you when you find my solution helps you...
I hope this solution helps you to fix your problem.Thank you and good luck.

Power supply most likely... It's a common problem with this particular model and we've seen quite a number of them for exactly what you're describing.
You need to replace 19 caps in the power supply 4) 3300uf/35v, 8) 2200uf/25v, 6) 1000uf/10v, 1) 1000uf/16v and you can go a little higher in the voltage of each cap for greater reliability.
It's best to have an ESR meter also and test the remaining caps as well.

This is probably caused by faulty capacitors in the power supply. This is a common problem with this model. If you no longer have a standby light, it could also be caused by an unidentified short on the main board. Hope this helps you out.
