Sounds like a main board issue. With a black screen and no remote functions . Does the Vizio logo stay white or orange?

SOURCE: Vizio GV42L 42inch LCD/HDTV

there are several possibilities. first if the unit comes on and the "VIZIO" light turns white, but no picture or sound, then the main control board is most likely the issue. could be the LCD control board(s) depending on model one or two. and ultimately could be the power supply on the upper side....if the "VIZIO" light does NOT turn white, the whole power supply unit is out. after that, would have to scope the circuits to find out. Seems that the control board is the most common and tends to happen on many different sizes. new board will be around $350.00. Might get lucky and find a used one, but it MUST be EXACT part or it wont work right. if you dont find one or want to sell yours for parts, id be interested in the screen. can reach me at kmarlin@grandvalleygolfclub.com. thanks, keith

Bad capacitors in the power supply. Open it up and look for swollen electrolytics.

SOURCE: went blank sound and picture went off will not

Most LCD tv's having a lot of bad caps in the power supply ,that makes for really weird things happen, since they work like a computer during boot. For that 2-3 second "boot" the processor in the set checks for a combination of things and if those caps go bad in the supply the set will show a wide variety of symptoms.
Usually the set won't start for a minute or two and sometimes longer, after that comes some weird things like lines and what not and the set finally just won't come on period.
I could write a book about how simple fix like changing a few caps causes all kinds of phenomena..lol

Green light but no backlight or video or blackscreen.




I had one that had a black screen and fixed the problem by repairing the inverter. When I opened the unit I looked at the capacitors on the inverter board and found them swollen. I looked at the bottom of the board and found that the fuse had opened up. The caps were a cheap quality low temp variety 150uF at 25V I replaced them with 330uF 25 volt 105C caps. I then replaced the 2.5A surface mount fuse with an axial 2.5A pico fuse and the TV worked beautifully.

Backlight shutt off


if. it works for about 3-5 seconds and cuts off
then the power supply is the problem..
open and look for capacitors that is swollen, or change the 2x1000uf 10v/16v, change the 2x 470uf/10/16v ,or the 2 small caps by the inverter
may be swollen, you can use higher voltage caps , no problem

Im looking for a dixon tms8 circuit diagram


Are you trying to repair it? If so you dont need one. Test the mosfet to see if they are shorted. Replace all needed, look on board for bad components, such as bad or leaky caps, burned diodes, check other parts around each one. Check in transistors for short or opens, replace as needed. Look for input caps swollen etc, etc. they are all built almost the same way, some with better parts cheaper ones with lesser an weaker parts.

My lg32lc46 tv will not come on from red light.I've had a peep inside, all 4 of the 10v capacitors have swollen tops.The rest of them look ok.


That peep was probably the sound of a swollen cap out-gassing (dead). This means a trip to the service shop. Sorry

Coleman rooftop air conditioner - Unit's fan works well, but when turned to A/C, the compressor short cycles: 2-3 sec on, then off for 15 sec, then on / off again. The compressor gets pretty hot...


It could very well be the capacitor which I would check first because it is a cheap fix. If the capacitor looks pregnant or swollen it could be shorted. You can check it with an ohm meter if you have one. Disconnect the capacitor, writing down where the wires go. Set the ohm meter on the highest ohm setting, and touch the leads to both sides of the capacitor. If the needle goes up and then bleeds back down, the capacitor is good. If the need goes up and stays up, the cap is shorted. If it doesn't move at all, the cap is open. Either shorted or open, it needs to be changed.
Worst case could be that the compressor is "locking up" or the piston is swollen and will not pump but for a few seconds before is seizes. This would mean a bad compressor. Hope this helps.
