Question about Akai LCT2662 Television

1 Answer

Akai LCT2662 We have this tv here in our shop - we have replaced caps after caps - the tv is playing fine the only problem is as soon as you turn on the tv a high pitched squeel starts and will not stop until you turn the tv off. Instantly the squeel starts and stops as soon as you hit the power button.

    same here, it's problematic... The tv tuner went bad, but everything else works. I only get the high pitched audio feedback when using it as a PC monitor. Using it for gaming on a 360 no audio issues on the RGB's. But the ypbpr is buggy as hell too, real picky on what u plugin working.

You're getting some feedback on the secondary transformer - most likely... Try to isolate where the pitch is coming from and see if it's harmonic. May just need to be glued down or have some leverage place against it...

I need to know the amp size of fuse to replace on AKAI LCT2662. thanks


If you have the original fuse, it's the number stamped on one of the end caps after the three letters denoting the fuse type. Most manufacturers also print the fuse rating on the power supply circuit board ("Caution: replace fuse only with...")

I have one of these sets in the shop now, but I haven't opened it yet. Post a reply if you can't find the fuse type and rating, and I'll let you know what my project uses.

I assume you already know fuses in TV sets don't blow by themselves, but indicate another part is shorted. Check the diodes, transistors and power ICs in the power supply before plugging the set in. If you see any bad capacitors, fix those also.

make sure the caps you installed are the exact replacements. Changing voltage capacity or timing will cause the circuit to fail.

Are you willing to fix a power supply for a Akai lct2662?


You may have inadvertently swapped one of the caps and didn't install it in the correct polarity... Or one or more regulators are also bad... Or there may be some more and severe damage caused by the swollen (popped) cap - especially if the cap was in the 100mf range or above...
Can't really quote something like that until I was able to see and test it. However, I will charge the same as our shop rate: $29.95 plus shipping for the estimate and based on the estimate if you choose to have it repaired I'll waive the $29.95 - shipping is repaired or not.

Power supply most likely... It's a common problem with this particular model and we've seen quite a number of them for exactly what you're describing.
You need to replace 19 caps in the power supply 4) 3300uf/35v, 8) 2200uf/25v, 6) 1000uf/10v, 1) 1000uf/16v and you can go a little higher in the voltage of each cap for greater reliability.
It's best to have an ESR meter also and test the remaining caps as well.

Akai LCD, Model: LCT2662


replace all the capacitors on the board. The ones that were originally place on the board are defective. I would replace them with the next larger voltage rated capacitor.

Tv won't turn on


The problem is the electrolytic caps in the switch mode power supply. They are located on the output side of the supply board. You can tell which ones are bad by the "bulge" on the top of each cap. All need to be replaced..
