    My ilo LCT27HA36 doesn't turn on, I tried rebooting it by shutting off the power, but that didn't help. When I hit the power button the red stand-by light just blinks.

I had the same problem. Then it worked for a while with me unplugging it and plugging it back in. Then one day it bit the dust. Nothing but the red light.

I found the solution on this website and I am trying to find it to thank the guy who posted it. For less than 10 bucks at Radio Shack, I was able to fix the problem with his instructions. And I know little to nothing about electronics. What it boils down to is this:
1. Lay the TV face down on something soft.
2. Take out the gazillion screws in the back until the back panel(s) come off.
3. Where the power cord plugs in, there is a ground wire going to a screw and another plug that you can undo. On this circuit board lies the problem.
4. Remove the circuit board (there are several other plugs on it. They all fit only one way, so I didn't pay much attention to how they came off.
5. Look on the board at the light blue cylindrical shaped capacitors. I don't remember how many there are, but look at the top of them. Find any that are bulging slightly at the top. They should be easy to spot. I had six on mine that were bulging. If you are handy with a soldering iron, remove the bad ones, making sure where each one comes from. There are a couple of different types/sizes. It is written on the side of each the resistance and what I assume is the voltage.
6. Go to the local Radio Shack and purchase new resistors. Note: I had some that were 1000 um and 36v or something and some that were 440 um and 16v. I couldn't find an exact match on one of those, but according to who I got my instructions from, as long as the resistance (um) number is the same, you can go up in the volts. So I ended up replacing some that were 16v with like 35v but the resistance (um) was the same and there are no problems.
7. Solder them carefully back into place. The circuit board is clear about which hole is positive (+) so don't get them backwards. The ones I bought from Radio Shack had a stripe on the side that was negative.
8. Put it all back together, and there ya have it.

Cheap fix. I admit I was darn skeptical it would work. I had already bought a new tv, but decided I wouldn't be out much if it didn't work. But it is working like the day I bought it again. And, it has a better picture than the Philips LCD tv that I bought to replace it.

Wish I could find the guy I got that info from. I was very impressed and grateful.

Hope this works for someone.

    do you have the original article that you found for this fix? if so, could you post it? thanks!

  • jgantreat May 12, 2011

    I would not recommend using the radio shack brand because the temperature rating is not high enough. you need 105c high temp capacitor. a good place to get them is herehttp://www.youdoitelectronics.com/id1030... get part number # VHT1000M16 made by NTE, I replace the capacitor in my tv and it is work just great. I hope this will help good luck.

Just FYI, I have fixed 3 of them and on all 3 of them it was the capacitors on the power board. The capacitors I changed on all 3 I got at mouser.com. They were: (3)-1000uf 16v PT#667-EEU-FC1C102, (2)-470uf 35v PT#667-EEU-FC1V471, (2)-1000uf 35v PT#667-EEU-FC1V102, and (2)-220uf 25v PT#667-ECA-1EHG221 the last two are located under a heat sink that you have to remove to replace them. The cost was around $15.00 with shipping for them. This is all I had to change on the ones I fixed but yours may not be the same i would not know without looking at it. Good luck and I hope it all works out for you all as it did for me. If it works for you feel free to contact me and say thank you at thanks@robbob.net

KUDZO601 -- THANK YOU SO MUCH FOR THE INFO! After driving to 5 different radio shacks and slowly collecting all of the resistors that I needed I finally gathered them all. When I got home I soldered them all on and I even got the higher voltage like you said.. and low and behold THE TV WORKS AGAIN! I was minutes away from purchasing a 400$ tv this afternoon, but I decided I'd wait and try this.. Your idea.. and I'm SO GLAD I DID!! you saved me 400$ or more! Thank you so so so so so so much! I am so grateful!

Name here is Barry. Been in electronics over 40 years. What you call resistors are in fact capacitors. And they are rated in farads. Units of capacitance. You put resistors where caps are, set will self distruct. Take a electronic course at local community college.Learn the lingo and parts. You just might save cost of new set. Thank you.

    does the temperature on the capacitors matter because my old capacitors which i took out had a temperature of 105 degrees celsius and the new ones i bought have up to 85 degrees celsius

  • John Dube Dec 08, 2010

    Hello; The temp rating is EXTREMELY important ! The 85 degree will likely run VERY hot and can explode. I have been in the TV repair business for 50 years and I know what I am talking about. Take those 85 deg out and toss them. Get the right ones. John

    Hello mrtech1948, I have been in the electronics field for 17 years I own my own small business repairing car amps and other electronics like big screens ans home stereo, etc. I have one of theos ILO LCT27HA36. It used to work but you would have to wait 5 minutes then push the power power button then wait another 3 minutes and the screen would appear. Well now no red light so the power supply took a ****. I tested some tansistors that turned out good the came to a Y2045DN Shcottky Barrier Diode. I thought it was a transistor but found out what it was. So I don't know if I was testing it right cause from pin one to pin 3 I got .000 ohms. So I finaly bought one on Fairchilds site for $0.91 cents. I have been readind and have seen that capacitors have been going bad. So I am gonna take it back apart and check the capacitors. I used to have an ESR meter but lent it to a friend and never got it back and can't afford a new one right now. Any thoughts to what could be going on? One day I shut the TV off and came back and the red light was not on anymore.. If you have any sugestions please let me know what to look for or test. I have an oscilloscope if that helps me with this. Thank you for your time. I'll be waiting patiently to hear from you. Contact me at skinnman33@gmail.com if you would like.

This worked for me: Reset your TV. Unplug your iLO TV from the wall and remove any connected devices. Hold the front power button in for five seconds, then release. Plug your TV back in, turn it on and confirm that it is working again.

    I decided to purchase a surge protector/power cord that has a few outlets on it. Now I just turn the power cord off for about 5 seconds, turn it back on and then power on the TV. This saves me the hassle of unplugging the TV from the wall (which was very difficult because it is in an entertainment center). I no longer hold the power button for 5 seconds to reset because I found that this was not needed.

Tele turned itself off, red light blinks 4 times then pauses and blinks 4 times again.


You can try unplugging it for a while and then plugging it back in, but according to the manual, the standby LED:
Lights up red when your TV is in PC power saving mode. If the LED blinks in red continuously, this may indicate the TV needs servicing.

TV won't come on, it just stays in standby mode The red led just blinks when you try to turn it on and hear a little whistling noise if you listen closely. I was thinking it could be a power supply issue...


Hi.

The TV staying in standby and the light flashing indicates that the TV is in fault mode (often called protect mode). This happens when an internal fault is detected, and the main board set the unit in forced stand-by with the led color changing.

Before doing anything else try disconnecting TV from power for ten minutes. Restart the TV with no device connected, leave it on for a while and see how it goes. Test the TV with different devices (eg. DVD, VHS,sat box, console etc .)

In your case it looks like there is no clear indication toward a particular fault. The TV coming on at random times, may point at a defective PSU, but other failures such as defective main board, overheating, defective inverter, or faulty Timing controller (TCon) may result in the same problem.

The most common fault that may cause the symptom you described is PSU. Unless there is clear sign that the PSU is damaged, this is still far from being enough to decide that PSU is the culprit. The power supply must be tested before replacing parts. Testing is done reading PSU out on different voltages. This is an operation that must be done by a trained repairer.

The high pitched noise may be given by a defective PSU capacitor. In that case the bulged or leaking capacitor is usually easy to spot looking directly at the PSU.

To book a repair call the manufacturer at the number listed on the owners manual.

LED blinking red


A red blinking light usually means the system is in standby mode.when you press power or TV it should turn on and be green. Try manually turning set on or off.

Model number LCT27HA36..will not turn on????


This TV is using a power supply MLT168A that has defective capacitors. Replacing the capacitors might fix it, but in some cases the failure is more then capacitors.

No Power


It's possible your TV when into protection mode. This happens when a part is burned out inside your TV to prevent further damage.
Try unplugging your TV for 30mins. Then see if the problem still occurs.
If the problem is still there, you may have to take it to a repair shop to diagnose the problem.

ILo tv


It looks like the power supply failed on your TV. If the LED is solid red or green, it could be some leaky or dry capacitors but if the LED is blinking, the failure is more complicated to repair.
I service these power supplies. If you need more info you can send me an email to jah2mil@hotmail.com
