SOURCE: tv wont turn

The blinking red light at the the front of the television is the "Diagnostic STANDBY/TIMER LED".
This little red light will blink 2, 4, or 5 times and then stay off for three-seconds. And blink again for 2, 4, or 5 times. This cycle repeats. The most common diagnostic code is the 4-blink code.

When the red LED blinks 4-times, it means one of two possible causes:
1) +13V is not supplied on the A-board. Or, 2) IC502 is faulty.

It is best to take this television set to a repair facility and ask that the +13V power supply be repaired.
The copper tracks and integrated circuit pads are very thin and delicate on the KV-24FV12 circuit board, and will easily lift off of the circuit board, if the incorrect desoldering tool is used. Unless one has a good quality PACE vacuum desoldering unit, one should not attempt to repair the television.

SOURCE: cpu can not boot

I don't think it is a ram issue.Try this when the computer is booting,hit the F8 key. That boots you into safe mode where only the most necessary drivers and programs load. If it loads in safe mode that is good. A little bit of daignostic work can locate the problem after that.

Lg tv screen keep getting dark, I've tried all Lg fixes and the brightness just keep going darker. Nothing happened to it just turn on one day. LG model 32lf5600


Back - light problem. Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis.
http://electronicshelponline.blogspot.com/
To some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS]. In such cases, the power supply board might need replacement. To some models sets, the back-light inverter and SMPS section circuit will be integrated at its main board itself. If so; the main board should be replaced. To some models of sets, all these section circuit will be integrated at its main board. If this is the case, you have to replace the main board.

We have 2.0 HP inverter wall mounted LG aircon, when we turn on the ac, the indoor unit only is running and shut down after 3 mins. What is the solution?


Hi Marie, does the green indicator light on the front panel flash after it shuts down? If it does...count how many times it flashes this will refer to a fault code diagnostic.

I have a neo plasma LG air conditioner, i am having problems switching on to cooling, sometimes it works, other times it is just circulating the air, making the room hot, it is 4 yrs old.


Possible problem with the thermostat which might be sensing the wrong temperature and so is not switching ON the compressor. So if the AC works once it is ON then the gas and compressor seems good. So you must check the thermostat and control board. Set the AC to a lowest temp and try.

Hi, i have a problem with my lg 32" ld350 tv..it


Hello.
This is a thermo-related issue. It happens when some parts in your TV reach certain temperature and fail creating short so TV shuts down and goes into protection mode.
In your TV the only thing that you can do is to replace Power Supply and hope it would help. Main board generally has nothing to do with temperature. Another probability - LCD panel itself (more likely back light inverter boards that are part of the panel, you can't order them separately).
There is inexpensive way to determine if it is power supply or not. You have to purchase fast-cooling spray that technicians use for diagnostic purposes (you can buy one in electronics components store).
You have remove TV rear cover so you have access to power supply board (the one where power cord goes). Turn on TV and let it run and eventually shut down. After that unplug it from wall outlet and use spray to cool down power supply board. Make sure you don't spray too much or you cooling anything else besides that board!. Let residue evaporate and plug TV back and try to turn it on. If it act OK and stays on for long time again - replace power supply and you should be OK.
Otherwise it is time for new TV. Panel is too expensive to replace.
Regards.
Russ.
