Re: Curtis LCDVD244A
My freebie is doing the same exact thing, I get a quick flash of light at the bottom of the screen but I cant see an image, not even with a flash light to know what selection it's on ( cable, DVD, etc. ).
I have it hooked up to cable & don't see or hear anything.
I found 2 fried Ceramic Capacitors # 5J 3KV near the outsides of the inverter board near where the back lights hook up.
Ebay has several different versions so I'm going to try to find the correct ones and replace them, Ill report back if that fixes it!Comment

For some reason I'm just not going to let this 19" TV defeat me. I guess because I have a schematic to work from I feel like I'm oh so close.
History- while adding a turn-on circuit I let a small screw roll under the power board. Worked through all of that circuitry, probably replacing a MOSFET and PWM controller that were not bad but I was following the service manual. Finally figured out that the power supply is in working order when the inverter section (for the backlights) is disconnected. When the +12 supply to the inverter is disconnected the +12 and +5 will come up... -
I have a tripp-lite aspint 3636vr inverter charger which blow some of mosfet transistors. I replaced them repaired also the driver circuit and tested but the mosfets burn again.
It work very well as inverter and also as charger if I let the rear switch in auto mode (inverter) and charger only(charging) but in auto when I connect the feed line 220V AC first time it pass ok to line and start charging the batteries but when I remove the feed line it pass to inverter mode and if I do it again the second time when passing from charging to inverter the Main transformer start making a...03-06-2023, 07:07 AM -
Hello, I have this Hp pavilion 1030 G1 that starts with a single light on caps lock then it turns off, measurements at the coils, meter in resistance mode (not continuity mode) are as follows: The problem started just after it fell from a desk to the ground. I can't find a boardview or a schematic diagram anywhere, please help me 🙏

If I had a solar fed grid tie inverter (GTI), a modified sine wave inverter, and a power outage occurred, what would happen if you disconnected mains, backfed the modified sinewave inverter (MSI) into house power, and hooked up the GTI to the output of the MSI, would it work?
Next thing is trying to charge the batteries using solar power, but that's another issue ... -
A1707 PPBUS has a partial short to ground @ 50 ohms.
VCORE to ground is 4 ohms.
Between PPBUS and VCORE I get 50 ohms as well.
Is it safe to inject 1-2 volt into PPBUS?
I remember piernov on Logiwiki stating that if PPBUS ohms to ground is LOWER than VCORE ohms to ground it is probably safe to inject small voltage into PPBUS. If it's the same resistance to ground it is not. But what about when PPBUS resistance to ground equals resistance between PPBUS and VCORE eg 50 ohms AND VCORE resistance to ground is lower eg 4 ohms? Is it safe to inject voltage into P...12-20-2021, 11:19 AM
