Coby 40 LCD flatscreen. Went dead after 2 months. Power supply circuit board fuse [6.3a/250v] is blown. Tried a jumper with a 7 amp and it blew right away. Direct short someplace in the components of the power supply board. Do not have much experience past this point. Any ideas besides using it for spare parts?

Hello. My tv will not turn on. I metered the power circuit as far as I could, and it looks ok. The fuse on the control board is good. The power switch meters good. When the tv failed I heard a small popping sound, but did not smell any smoke from a damaged component. I cannot tell if the problem is with the control board, or with the picture tube. Thanks


It sounds that the power supply regulator section or main board has the fault. Check it with the help of schematics. If you are not handy, seek any technician's support. ... Emerson EWF2006 TV

Need help with my l26wd12. Will not come on. Can see red light by the buttons but that's as far ad it goes. Don't see any damage to board or components. If repairs are to much I am willing to scrap.


99% chance to have it fixed by replacing the main board. 1% left for the power board and if it's the later it can probably be fixed by replacing a few capacitors on the board.But that is much less likely.Main boards go for about $60 a ... Flat Panel Televisions

Hi I have a Samsung LE40S67BDX/XXE, Version AM02. When i try to start it up is it a relay how go on and off. REL 801 ( I work with repairing other electronic equipment, so I'm family with electronic) When I look at the circuit board it look that the capacitor CM809, CM807, CM811, CM 812 are little big at the top. Have you any idea if it only this or if it are more components how are broken? The TV start up sometimes.


If the tv starts sometimes, it is a power supply problem caused by bad capacitors that commonly bulge, change all the capacitors you mentioned because any capacitor that shows that condition is probably open or very close to it, and make sure they ar ... Flat Panel Televisions

My HP LC4276N TV is 27 months old. A few days ago, the sound just ceased working. Of course, I checked the settings to ensure that "mute" was not activated and that the setting for speakers was "on". I then also tried connecting auxiliary speakers, but to no avail. Could this have been caused by a blown fuse? A bad capacitor? Or is there another likely cause? I would love any detail on how to check any of these potential problems, or any suggestions for repair. (I have no experience in t

You will have to replace it. The reason the fuse is blowing can also be to X-sus board as the two sustain boards are capable of frying each other. They cost you about 170$ together. If you can get me the part numbers off the boards, along with any re ... Flat Panel Televisions

I have a Samsung PS50Q97HD plasma TV that keeps blowing new boards and I don't know why. It came to me with a faulty YSUS that had damaged the VS supply section in the PSU board. I fixed the PSU and fuse and have good VS voltage now. I replaced the YSUS main. I powerd the TV and the upper YDRIVE (Yscan buffer) board chips when pop. I put this down to it getting damaged unseen when the YSUS went faulty. I replaced the YDRIVE upper with new and then the lower board went faulty too (holes blew in t

Hi, I bought a Vizio L32 HDTV10A that didn't power-up. There were charred components on the power board (an 8-pin IC with heatsink and 2 resistors). I replaced the power board, and the power LED then turned on (yellow) when power was applied. When the ON button is pressed, the power LED turns green for roughly 8 seconds and then the power LED turns yellow again. Nothing else happens. I checked many components (fuses, capacitor ESR, diodes, etc) on the main board and the master and slave inver

I have a HLR5656W Samsung. This question was asked before, but I never saw an answer. I have the same issue. "I have tried two different devices on the hdmi input and neither work. I am trying to find the part number for the circuit board that contains the hdmi input. Since I see no way to resolder or repair the connection I assume the board needs to be replaced? I was unable to get a part number over the phone. I was hoping to avoid taking the tv apart to get the board out and find the number

I have an Insignia LCD 32", is it common to only get 3 volts dc on one pin only on the power supply board (6HA0112014)? I tried a board from River Valley Electronics and got the same thing.

When I turn on the TV, green led comes on, then after about 30 seconds red led blinks once, then green resumes. The green led stays solid.
