Re: Another vw42l problem
It was going into shut down mode, up until i slid the mosfet off and now it stays on. That is correct, It would not come on. I am getting 24vdc on the new supply however. The old one did not put out any voltage other than the 2vdc for a split second
Could the shorted mosfet cause the old power supply to go out?Leave a comment:

Re: Another vw42l problem
It has a loud pitch squeel though. What would make the solder to boil out of that peice?
Looks like this

Re: Another vw42l problem
Ha. Yea. so i noticed that a transistor/mosfet, idk on the inverter was smoking. I touched it with a screw driver and it slid off its place. Tv came on immediately and the piece is not in the right placeLeave a comment:

Re: Another vw42l problem
So bud, I replaced the ic. Still nothing, exact same thing. so I bought a power supply. Now there is clicking on the power supply and a buzz. Then there is a click on the inverter board. blue led on the tconn. Then shortly there after it all just stops. No buzz or light. Power supply made heat quickly i thought. 24V shoots up to 3.5 Volts and then goes awayLeave a comment:

Re: Another vw42l problem
Good deal.Thanks Bud!! I have got two ordered from digikey. I think i will do ok getting the old one off it doesnt appear like it will take alot of heat. I will post a picture after i get the new one on.Leave a comment:

Re: Another vw42l problem
I did have a 1157 bulb. It would not come on when the set was turned on
For some reason when i touched the lead to the ps_on there was a blue led that came on the t-conn.? It went off when i took it off. Hope i didnt mess anything up. When i was reading the 12v pin for it read 2.12 for not even half a second.Last edited by abarker8323; 04-24-2013, 07:08 PM.Leave a comment:

Re: Another vw42l problem
Immediately upon turning the power on, the 24v pin it goes to -60mv and goes down and hangs out about 20. The 12volt pin going to main goes to 2.12vdc immediately and then starts going down quickly.Leave a comment:

Re: Another vw42l problem
So assuming i have the numbers in their respective places on the circuit. Black lead to chassis ground.
1 Css 0.0
2 Rfstart 0.0
3 Cf 0.0
4 Rfmin 0.0
5 OPOUT bounces between 9-13mv
6 OPIN- 2.48vdc
7 OPIN+ 0.5vdc
8 EN1 0.0
9 EN2 0.0
10 GND 0.0
11 LVG 0.0
12 Vs 13.09vdc
13 N.C. 0.0
14 OUT Starts at 200mv and decreases
15 HVG Starts at 370mv and decreases
16 VBOOT 10.2vdcLeave a comment:

Re: Another vw42l problem
ok, This is a complex little booger. How are we going to start testing this thing?Leave a comment:

Re: Another vw42l problem
R621A 0.1 ohms
R621B 0.1 ohms
P/N IC601
DLA001D
DEI (04) 928W807
Those are very hard to see but i think i have them correct.
The (04), Is inside a circle, not parenthesis
when you find the spec sheet can you send me the link so i can see it? maybe i can learn something. went to alldata but dont know what i am looking for or what numbers to put in.Last edited by abarker8323; 04-22-2013, 04:44 PM.Leave a comment:
