I have a JWIN DTV3212 LCD TV with a BP-200AD power supply. With the help of this forum I was able to replace a bad capacitor, and get the set working again. It worked flawlessly for over a year, until a nearby ligntening strike. After the strike, there was a puff of smoke, and the TV went black.
I opened the box again and on the power supply was a small burn spot where (what I think) a resistor used to be. The resistor was completely gone with only the stubs left. I don't see any other (obvious) problems, and would like to try repalcing this Resistor(?).
The problem (I guess obviously) is I have no idea what to replace it with, as there is nothing left of it. The board is marked R10 right next to where the resistor was. I had thought that at one time I had found a picture of this power supply on this forum, but my searches have had no sucuess.
Does anyone have a scematic of this board. Even a good picture would work, and I may be able to identify the missing part.
TIA
Mike

Vizio e601i-A3 - Has Sound and Display, But No Backlight - Bad Power Supply Board or Bad LED Bulbs ?I was given this TV from my great uncle. He said it just wouldn't turn on one day out of nowhere, replaced the TV, and gave it to me to possibly fix and use for myself.
Upon bringing it home and plugging it up, it showed a standby light.
I powered it on and without a flashlight, the display showed the "V" but the lighting is very dim, but visible.
The screen seems to blackout and stay black, but with a flashlight I can see the display.
With my Playstation 4 connected via HDMI, and running a game I can hear sound.

Hi
I am trying to repair an ancient Dell 2209WA Monitor which suddenly shut off with a pop sound. On investigation found that one of the fusible resistors had blown. Further investigation identified multiple components as faulty because of which the fusible resistor blew. Please refer the attached circuit diagram showing the components that were found to be damaged.
1. FR950 - blown fusible resistor - 0.2 Ohm 1W
2. Q950 - shorted Q950 MOSFET - 650V 10A N Channel Mosfet
3. R835 - Blown Resistor - 20KOhm SMD resistor
4. D930 - Shorted Schottkey Diode... -
I have wanting to do this project for quite sometime now and I finally found a switching power supply that will work on this desoldering gun station ZD-915 that the original switching power supply took a shit and just was not worth trying to fix it because this switching power is not quite big enough to handle the heater element and the vacuum pump
One note when I tested the switching power supply and the voltage control board I noticed that this desoldering gun heat up much faster than the original switching power supply which I was really surprised by to the point that I might buy... -
I have a quad charger that is split into 4 separate sections and one section doesn’t charge anymore. I have located what I think is a thermistor and on the shrink tube it says 125 degrees C. I cut the shrink tube and it's a 33 ohms resistor. It measures a little less than 1/2 inch in length. I am including pictures of it. Please help me identify it. So, it should test at 0.4ohms and probably go up in resistance with the rise in temp. On the board it clearly says R for resistor. But it has to be a special one.
Resistor shows orange range silver gold and green lines.
Thanks in adv... -
Hello guys, I had a problem where I didn't know the value of the burnt SMD resistor in the power supply circuit of the BenQ G922HDAL monitor.
In one of the parts, there is a burnt SMD resistor which leads to the LD7560GS IC as shown in the picture below.
How to determine the appropriate SMD resistor value for this condition? Thank You...
