Question about Akai LCT2060 Television

1 Answer

I have a 6 Year old AKAI 26" LCT2660V. While watching a movie last night, The screen went black in the middle of it and won't come back on. When I first bought this it started doing the same thing and it took Akai close to a month to get whatever part to get it fixed. Is this a known problem with this model and what can I do about it?

Sounds like power regulator board fault. If you wish to get some details; visit the site linked here. Pull up older posts.

Thanks for the advice, premtech. My LCT 2662 finally died from power supply problems after about two and a half years of use (it started giving us problems about six months ago). After reading the fixya.com recommendations to replace the capacitors on the power board, I decided to give it a try. I took the back off and was grateful to find the power board to be easily accessible. It was immediately apparent that several of the 2200uf capacitors had all bled out. There was crusty brown dielectric everywhere! The 1000uf appeared to be in good shape, but I ordered a new set of those anyway, along with the 2200uf/25v caps as well. I replaced all of the 2200uf caps first, since they were pretty much all fried, and tried the set out. The red power light came on, but when turning the unit on, I would just get a momentary flicker of the main screen, then nothing. After poking around the power board some more, I noticed that the four 3300uf caps also look to have melted out. So it was back to the Jameco website to order more parts. After replacing those four caps, the tv mercifully came back to life and has worked like new for about an hour now. I did not have to replace any of the 1000uf caps, but who knows how long the original ones will last. Oh well, I have to parts and know how to fix them if they do burn out. Thanks to all those who suggested the fixes. You sure know your stuff!

Hello to all from Tom Arnold, WA6OVP

Subject: Repair of computer monitors or flat panel TV’s.

History:
Recently my wife's 27-inch AKAI (LCT21AS) 27-inch flat panel HDTV with DVD player quit working. Years ago, when I had an analog computer monitor quit operating; Joe Fadden WA6DDF had mentioned to me, that often computer monitor problems were caused by the monitor's power supply. Joe also said these power supply problems were often caused by failed electrolytic capacitors. Joe said he was able to fix many computer monitors by just changing all of the power supply electrolytic capacitors. Rather the fix that failed monitor, I just a bought a new one.


Symptoms:
The inoperative HDTV had been bought at COSTCO and had already been returned once to a COSTCO repair center for repairs. Cost to ship and insure the HDTV was 67 dollars. We received back a new HDTV set. Turn around time was over a month, with many long distance telephone calls being required. The new HDTV worked for about three months after it was received. When the returned HDTV failed, it trapped a DVD disc that had been left in the HDTV DVD player. The new HDTV failure symptoms were the same as the original HDTV failure. The red led indication would not change to green when the remotes power on button was pushed. There was no picture and no sound. The remote is required to operate the TV set.


Economics:
My wife's HDTV with internal DVD player was very expensive. Worse yet, the trapped DVD disc was the movie Flash Gorden Space Soldiers 1936. A local TV shop wanted 85 dollars to look at the failed HDTV; repairs were 75 dollars labor an hour plus parts. I quickly figured out that if I could fix the problem it would save a lot of time and money.


Internet Search:
I checked the Internet to determine if other AKAI owners had similar problems with their HDTV sets. There were lots of AKAI 27 inch and 32 inch HDTV set owners listing problems. Without exception all of the complaints concerned the HDTV power supply PC board and failed electrolytic capacitors.


General Internet Consensus:
Most of the AKAI HDTV sets worked just great and that many had been sold worldwide. There were some AKAI HDTV sets that did have power supply problems. Most of the AKAI HDTV set owners were not very pleased with either AKAI or the COSTCO response to the inoperative HDTV power supply problem.


Trouble Shooting:
All electrical power was removed from the HDTV set. The HDTV was placed face down on a workbench with a piece of cardboard to protect the display screen. The HDTV back panel cover was removed. There were many screws of several different sizes. The power supply PC board was separate from the rest of the set's components and was easily identified. The power supply PC board contained several different individual different voltage power supplies. Three electrolytic capacitors located on the PC board had obviously failed. The tops of these three capacitors were puffed out. Often when electrolytic capacitors fail they get over heated and the top of the capacitor is puffed out displaying an over pressurized appearance. The power supplies on the PC board were of the switching type. Switching type power supplies are also used in computer monitors to save money and weight.


Power Supply PC Board Removal:
The power supply PC board was mounted to the HDTV back panel with several screws. These screws were removed. There also several multi-pin connectors attached to the PC board. These connectors were numbered with a black felt marker to ensure correct reinstallation. The connectors were Hot-glued in place. A sharp knife was used to remove the hot glue. The connectors were removed.


Repair:
The three suspect failed capacitors were easily removed. The three capacitors were each 1000 ufd and rated at 16 working volts. The other power supply PC board electrolytic capacitors were visibly checked. Three new capacitors were installed, they were rated at 1000 ufd at 25 working volts. On the PC board the three electrolytic capacitors were in just one of the power supply circuits and were identified as EC18, EC19, and EC20.


The New Electrolytic capacitors:
These were low impedance / high reliability radial lead polarized aluminum capacitors, they have a plus and minus connection pins. Correct installation of any polarized capacitor is required. The three new electrolytic capacitors were specifically designed and rated for service in switching type power supply circuits. Switching type power supply electrolytic capacitors need to be both very robust and designed for use in high frequency circuits. General-purpose aluminum electrolytic capacitors should not be used in switching type power supplies, if capacitors designed for switching power supplies can be obtained.


Final Repair Steps:
The PC board was reinstalled without the electrical connectors to the PC board being hot glued. The HDTV back panel cover was refastened. Watched episodes one through five of Space Soldiers. It was well worth the time and three electrolytic capacitors to fix the problem. The repairs saved a lot of time and money. The repair was very simple and not the least challenging. It took longer to remove and then reinstall the HDTV back cover panel than it took to replace the three failed capacitors.



Safety:
These types of repairs should not be attempted without a complete understanding of the dangers involved with working on electrical equipment, especially working around power supplies and charged capacitors. Proper desoldiering and soldiering techniques need to be used.

Conclusions:
Flat screen computer monitors and TV sets do fail. Repairs of electronic equipment can be very expensive. When your computer monitor or flat screen TV does fail, you might consider a visible inspection of the equipments power supply. A simple repair might save you a lot of time and money.

Change the capacitors located on the power (center) circuit board towards the top. They are C523 and C524 on the board.

Digikey has them for $6. .022 X 400V poly caps.

Screen goes black


Walmart has been accepting returns on these players because the manufacturer of this product line went out of business last year. Walmart was aware of it at the time of business with them. The best thing to do is take it back to the nearest Walmart and get a store credit and/or file a complaint on ripoffreport.com
