Akai PDP4225M red std/by light on

What values should I get when testing the schottky diodes? I've changed all 20+ caps on the power board. Thanks for the advice there where several bad ones but they were leaking from the bottom not the tops.

There is a difference between diodes and capacitors. The role of a diode is to rectify and some cases regulate voltages. Meanwhile, a capacitor is there to hold charges. Back to your question, to check an schottky diode, you need an ohmeter with a diode symbol, the reading starts like this .500, .600, .300. 125. still consider good forward bias. .1200 or infinite reverse bias is consider good still. But it shows 0 continuity then that diode is bad. You can also use ohm's law, resistance to also check a diode. Please e-mail me if you some further lesson at Stevebuy31@hotmail.com

Power supply filter capacitors and smoothing capacitors have warped. There will be some bad FET's, Diodes, and pull-up resistors too that need replacing. You can send us the board and we can repair it for you if you like.....

Your having a DC switching and regulation problem, its very common in these Akai models. I have repaired over 800 Akai LCD tv's so far since 2006. they all seem to have had the same fault scenario related to a similar problem like the one your having....

hi isolate ur power unit out replece ur resisitor & every other burnt items then check the schottky diodes in the secondary side &the electrolytic capacitors if bulgge or leak. if all this are ok , power then use voltmeter to test ur output voltages if ok , unplug your inverter  & power

If Z3 was shorted, there are 2 surface mount resistors that were damaged when Z3 became shorted and they have to be replace as well. The reference designator for the resistors is R65A and R65B, their value is 10 ohms and 1206 is the body size of the resistors.

Akai LCT2715 No Power


I have a different thread going, but saw yours and had a question. Is your light blinking steady and then off? or is it a blinking erraticly or even flickering? My bad caps (15 of them) were all on the secondary side of the PSU. I have been told (thanks to Jaimie Hernandez) if you have a steady blinking, then it is very likely that you have a bad zener diode Z3(27v/1Watt) shorted in the primary side of the power board. If that diode is shorted, it's very likely that 2 10 ohms resistors might be open, these resistors are connected to the cathode of Z3. Also check for bad caps on the Primary side.

I had a huge incentive to fix the TV, it is my wife's TV and she has been in my Man Cave since it died. How about that incentive.

Good luck
