Do you a schematic diagram on this Power Supply? I have bulged (bad) EC9, EC10, EC18, EC19, and EC20 Caps. I also have shorted Zener Diodes Z3, Z4 and Z5. I believe Z3 in a 27v zener, but do not know the values of Z4 or Z5. There also may be another shorted diode below HS1. Any component values or help will be appreciated.
Here are the values for the parts:
R104 and R105 are 100 ohms 5% 1 watt but you can use 2 watts.
R107 is 200 ohms 5% 1 or 2 watts.
C17 is 2200pF 10% 1Kv.
If I give you the values of Z3, Z4 and Z5, would you return the favor by telling me what are the values for R104, R106, R107 and C17?
I have posted this request 5 times for 2 months and no body gave me an answer. Would you be willing to work with me? E-mail me [email protected] and use MLT168A-fixya as subject
Thanks
Hi Jaimie867... thank you very much for your post, but I'm afraid it was a bit too late... I just brainstormed and used a 1oo ohms 1 watt for R104 & R105, and since R106 was 2 K ohm, I used a 2.2 for R106... from my electronic expertise, I know that they usually have some of those resistors in parallel thus equal values... it seems to be working fine now.... I'll e-mail you if I run into other problems ...you are the man... let me know if I can help with anything...thanks again

Hey guys: i have an mlti68a that flashes the akai screen for 2 seconds and the screen goes black again.. have replaced all "big" caps on ps board to no avail:do not here "click" on power-up...fets? , relay?...diode?...
please help... thx.jim
Ps. mlt168a no voltigis in secondary side
Hi guys,
You can find the service manuals at:

I have an LCT2701TD which I've been trying to get to work with no success (yet). It has a MLT166A power supply, but I bet it's pretty similar to the MLT168A. So my question to you guys is: how do you know what to replace (other than obviously bulging capacitors)? I replaced the bulging capacitors (EC18, EC19, and EC20) and the Z3 zener diode and still no success. I have a multimeter, so should I just start removing capacitors and diodes and testing them one by one?!?! Please give me some pointers if you can.
