Re: Panasonic SA-HT820V Home Theater System
Pin number 6 is reading .6V. All other pins are good....Last edited by CapsDude; 03-16-2021, 07:12 PM.Leave a comment:

Re: Panasonic SA-HT820V Home Theater System
Got the part and soldered it. Nothing shows up on the display. It powers up tho because the vhs side starts up. The connector tape is fine....Leave a comment:

Re: HP Pavillion DV6700
Because I don't want to buy the station that would cost more than the laptop is worth. It's just an old laptop I found, no biggie. I'd make more parting it out than fixing it and selling it. Granted, it'll take longer....Last edited by CapsDude; 03-12-2021, 02:38 AM.Leave a comment:

Re: HP Pavillion DV6700
Unless P/N is the model number then it doesn't list the model number on it.
NVIDIA GeForce 7150M GPU
Sounds like more money than Id want to put into it just by looking at the rework stations lol. Cant use a soldering iron?...Leave a comment:

Re: Panasonic SA-HT820V Home Theater System
Oh ok, I was already searching for a Panasonic 200V 200mA diode since thats what the schematic said it was. So it doesn't matter?...Leave a comment:

Re: Panasonic SA-HT820V Home Theater System
P1102 was already unplugged when I was doing the test. So if I wanted to fix it, is it a new diode or the power board itself?...Leave a comment:

Re: Panasonic SA-HT820V Home Theater System
Do I have to desolder and take the diode out to test it?...Leave a comment:

Re: Panasonic SA-HT820V Home Theater System
I think we set the VCR to zero point but not the DVD. How do you go about doing that?
Here's the top and bottom. Do I need to take the trays out?...Leave a comment:

Re: Panasonic SA-HT820V Home Theater System
4.94 Volts.
Ok so I was reading the schematic wrong because its a little different from my power board. I was reading it in the opposite direction. So it should read:
Pin 2: 31.8V
3: 6V
4: 6V
5: 16.5V
6: -.03V
11: 3.5V
12: 13.4V
TL1004: 3.5V
TL1006: 6V
TL1009: 13.4V
TL1016: 16.4V
TL1030: -.33V
TL1038: 31.6V
Fuse read good....Leave a comment:

Re: Panasonic SA-HT820V Home Theater System
So apparently it's under the board, or at least the label is. I knew that! What am I checking? Because Im not seeing those letters anywhere.
And where online did you find the schematics for it?...Leave a comment:

Re: Panasonic SA-HT820V Home Theater System
I was referring to L7200, it read 4.94
For P1102 read
Pin 2 - 0
3 - 13
4 - 3.3
5 - -17.7
6 - - 23.7
11 - 6
12 - 6
All other pins are ground or he -+.
Haven't located Q3306 yet but some of those voltage reading seem low....Last edited by CapsDude; 03-09-2021, 09:06 PM.Leave a comment:

Re: Panasonic SA-HT820V Home Theater System
The cable from the display was my first guess since I forgot to unplug it several times when taking off the front and it would yank it. It was pushed up a bit at one end but I pushed it back down. The othes side tore off a bit tho because of the angle in which its bent to connect. The end that connects to the board looks fine.
I found L7200 and not getting a reading. Newb question, is it suppose to be plugged in and connected when checking it?...Last edited by CapsDude; 03-09-2021, 07:10 PM.Leave a comment:

Re: Panasonic SA-HT820V Home Theater System
Oh, looked like othep pics of leaky caps. Right, I just thought it looked like it needed to be replaced. So besides visually, how do you check for a short with a multimeter?...Leave a comment:

Re: Panasonic SA-HT820V Home Theater System
I didn't notice anything visually, but I found a leaky cap on the power board....Leave a comment:

Re: HP Pavillion DV6700
Yeah, I figured I would part it out if the oven didnt work. Just seeing if maybe someone had another suggestion....Leave a comment:
