Hi aqhnc,
You need to change the whole power supply unit. Your transformer inside it might broken and need to fix.

I hope my solution may help you.
Thanks for using Fixya...;-)

Power Supply Issue - Green LED ON..no power up


tried to disconnected the 24v supply connectors going to the power inverter board which may the cause of voltage drop. after you disconnect then if still no output 24v dc coming from the power supply board the cause will be bad power supply board. check for an open resistance or bad regulators going to the 24vdc out. by the way you should connect all the connectors going to the main board to turn on the processor and the inv_on voltage going to the inverter board.

there is 2 problems that makes this tv have standby fault.. so here they are,!

1.)main av board ---the 8 leg eeprom loses programing just under LVD CABLE TO SCREEN -£14.99 from a guy or if you can program yourself 4.99 for the flash to reprogram,.

2.)POWER SUPPLY FAULT IS MLT199TL PSU. (UA4)AREA, SG3525AN (16 leg) Regulating pulse width modulator.

the first fault all votage at psu will be there ,, 5v / 12v / 24v

the second fault psu will have 5v standby but no 12v or 24v this will stop the secondary from fireing up.. hope this helps.

How do I tell if my power board is out


You can check that the power supply is getting power from the power cord. then check the fuse on your power cord. Last you can check the output power of your power supply. You can get parts from www.interliquidparts.com

The first thing you need to do is to check whether your power supply is working well.
To do this, you need to open the back cover of your tv.
You can immediately reach the power supply. Test the power output using a multitester. There must be an output of 5v,12v, and 24v.
24v is for the screen to lit up.
5v is for the the cpu supply.
12v is for the audio...
You can repair the power supply if it is not functioning or buy a new power supply.
To repair the power supply repace the regulator transistor,the opto isolator, the ic that gives the signal to the opto isolator and check for open resistor near the regulators.

I hope this will help.

Please tell me about power supply problem and solving diegrame


The power supply for HDTV is the board where the AC plug goes into. It is a very sensitive circuitry that can be easily damaged. Under normal circumstance it is very reliable. This is how they work basically. The AC current is rectified (converted into DC). Then filtered by means of large capacitors. The DC Voltage ( about 180 DC volts from 120 AC) is supplied to power transistors (usually FET or field effect transistor). The Transistor are switched at high frequency( usually over 100KHZ or 100,000 times per second) Which drives the transformers to step down the voltage. When the TV is off there is a standby voltage which is on at all times, and it is typically 5V. This standby voltage is the first thing a technician check for when troubleshooting power supply problem. When the TV is turned on everything in the power supply comes to life supplying power to every circuit boards which are of diffrent voltages such 12V, 24V etc. HDTV power supplies are very complicated using the latest technology employing power saving chips that minimize power usage on standby mode. Explaining the it in great detail would require many pages but this is just the basic.

Polaroid 26inch lcd tvred standby light on but power wont turn on. I've unplugged the tv, changed the batteries in the remote. The tv stays with the red standby light only.


You need to open it up and checking the voltages in the power supply sections, you should have 5v (for logic circuits), 12v for sound, 24v for backlight inverter circuits. Look for bad caps with bulging tops in power supply also.
