26LG30R MAINBOARD IS NOT WORKING


Check the power supply regulator board, with no load condition, and make confirm that the 12V supply line is OK, by connecting a 12V filament type bulb in place of load. if it is found OK, and no voltage drop occurs, be sure that the main board of this TV is faulty. If you wish to get some details, check the site linked here. Pull up older posts. Check the site in 'Mosaic' view. It will make search easy. http://electronicshelponline.blogspot.com/

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!

I have a KDL52s5100 it is not working(no lights, dose not t turn on) due to a thunderstorm. I have bought 2 powersupply board and a new main board and still nothing turns on no even a light.. please help....


make sure that all the voltages in the power supply output are present before connecting to the control motherboard. also confirm that the cables supplying the voltages to the motherboard are all matching e.g do not make a mistake to connect the 3.3v cable to the 12v terninal. just be cautios and your system will power up

Lost power cable for ns-22e430a10 led tv. tried 12v with 300 ma no good, tried 12V with 850ma still no go. can't find what the ma is suppose to be.


Thise are way too low for the TV to operate amperage wise. Your best bet is to go to Best Buy to research the correct power adaptor BEFORE you do damage to the TV. I hope that helps : )

How can I operate my LG 26LE5300 LED LCD TV in my motorhome the most direct way possible (i.e....without an inverter)? This low power (40-50 watts) TV has an external brick to convert 120 AC to it's...


1) You need to look at the output current rating (AMP) of this AC to 24dc adapter, this 24vdc adapter is a regulated switching power supply that will maintain 24vdc output up the maximum current rating and also has shutdown circuits if the over current draw is detect and also if the output voltage goes up beyond 24vdc to protect the load (TV).

2) To use 12vdc to 24vdc DC-DC booster, it should have the following spec:

A) The output current rating should be at least 20% higher than the load requires to give its head room.
B) It must have regulated output that will maintain the 24vdc when the input (12vdc) will vary from 10vdc ~16vdc or higher since your batteries will not maintain exact 12vdc all the time.
C) It must have good protection circuits that will protect it self from reverse polarity connections, shorted output protection, over voltage output protection.
D) It should provide AC ripple spec on the 24vdc output, it should be in the milli-volt range (you will always get AC ripple riding on top of DC when you rectify the AC into DC).

These are the minimum requirement for your DC to DC booster, which you need to protect your TV and your motor home from burning down.
I hope I explain it OK to you.

Ac adaptor on my 32 Protron inch LCD TV no longer work


What is the current output of the adaptor? If it is AC and you use only the 12v to 3v it is ok. But if the current output of the adaptor is DC and you use both 24v to 6v and 12v to 3v there is some danger if use the new one. Remember that DC current have polarity.

The original power specs


As I search the internet I found out no replacement for this kind of the adaptor model number 090-02180-13, there are some people looking for this kind of adaptor is a faulty a pervasive problem with the TV. There are literally hundreds of complaints on the internet. Most deal with a faulty AC Adaptor and the inability of the company to provide a replacement part.
I have a solution for this adaptor problem we better improvised the parts inside. The faulty parts of this adaptor arise in the transformer. This transformer is easily to burnt because of lower amperage. So we make it higher amperage so it can resist the load heat and cannot burnt easily.
Maybe you can do this for yourself, open the adaptor case, when open already look for the transformer, the visual picture of transformer is a bulky metal with many windings. Take this out and bring it to electronic shop that know how to rewind a transformer. Tell them to reworks or rewind the transformer, only the output voltage will be change input is the same. This is the

NEW SPECIFICATION:
  • INPUT 100-240 V
  • OUTPUT + 24VOLT DC AT 12 AMP
  • 12VOLT AT 6 AMP.
This is the result of new specification when the reworks or rewind is finish ,put it back to the adapter box,and then you can use it.This is higher amperage I mean it to you before,it can resist overheating.If ever happens that you can't find in your place know how to do reworks of the transformer here in philippines i do the rewind or reworks of the transformer ,but the problem is.very far to your place it needs shipment to carry this out .I price you 120 dollars including shipment and i assure it to you that adaptor will last long because of higher amperage .
When i search i found a site that can make an ac adaptor only you give the new specification and give where you are using the adaptor give the brand name PLTV-32 and they will make it..try this option also ..LCDPAYLESS.COM
