Upon plugging in the TV, a red readiness light blinks is then it goes into looping click on/click off cycle. Once this takes place, I have to unplug the TV to power down as the remote & pad become unresponsive. I have ohm tested all the fuses & found them to be good. I located a blown ceramic fuse on y board jumped it out and burened up a fet. I oreder used replacement y board. Unplugging individual boards as follows continue the clicking cycle: y-sus, x-sus, logic or control? I tried jumping the #3 & 4 pins on the logic board while jumping out ps on to ground on power cable coming from power supply to main board. also disconnected lsvd cable. Tv went into test patterns and patterns look good. I saw this on you tube. Video says to suspect lsvd cable or main board. I ordered used main, installed and tv repeats original faoult. I am going to order another main this time from Jimmy. P.s. also replaced logic board before this same results, both logic boards pass test pattern. I waiting for replacement main, could there be another problem if new main board act the same?

Re: Plasma Pn58B650 clicks on and off, after replacing y board with blown fuse
Your problem, from what you have described, is more than likely on the main board.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Re: Plasma Pn58B650 clicks on and off, after replacing y board with blown fuse
I was unaware of this site. I did a lot of research and based on what I learned thought the same. I also followed similar posts of yours and it reinforced the idea I may have order a faulty used main board. I will install new used replacement main board when it arrives and post how I make out.Last edited by chaswee1; 06-25-2013, 04:40 PM.Comment

Re: Plasma Pn58B650 clicks on and off, after replacing y board with blown fuse
I just replaced main board. You can hear the tv speaker when turning on and off. Tv does not click any more. I can turn on and off. when I first put on I get slight white light for an instant then screen stays black. I attemted menu with remote and button on tv, still no picks.Comment

Re: Plasma Pn58B650 clicks on and off, after replacing y board with blown fuse
It's more than possible your new main board is bad, since the test patterns worked you've proved basically everything except the main board as working. Also check LVDS cable is seated properly and 3-4 jumper is removed.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Re: Plasma Pn58B650 clicks on and off, after replacing y board with blown fuse
I left plug disconnected from y board to the lower boards. I did the pattern test jumping out pins 3 and 4 and got no patterns. I relized then to double check all connection and I caught where I forgot to plug back in. I then plug back in and tv fired up. Thanks.Comment

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.

I found a project in the electronics trash yesterday. A nice Argon SA1 audio amp with some electrical issue. Took it apart and saw that the 4A250V fuse was blown so started lifting components to find the short. Eventually got to two MOSFETs (model FTA14N50C) that are shorted and when i took them out the short was gone.
Now i didn't have any replacements of the same model of course but i found a couple with pretty similar spec i thought (K10A60D & K12A50D) and put them in. Also replaced the blown fuse with a 3.5A250V one. Checked another time for short circuit and plugged it in.... -
All left and right refers to looking from rear of TV (or looking from front with TV upside down)- TV came with vertical bars and no image. Found faulty TVS on left buffer board. Also replaced T-Con (may have damaged the original while hot air removing components, board has slight warp) and have full image but few horizontal lines on the screen. Some of the lines appears to be 2 pixel tall while others are 1 pixel tall.
- Disconnecting left and right buffer board potentially reveals problems on both sides with different signals (unless this T-Con require jumper like Samsung FB_TRDY1&3) Fault

I gotten a Carver CM-1090 amplifier from a friend who has kept it in storage for decades. Opened it up, thick layer of dust cumulated everywhere. Vacuumed it semi-cleaned, and blown off as much as possible the remaining dust. This is a 220V version.
On initial powered up with nothing connected - it works with all the lights and button indicator lit up as pressed, etc. I then powered off, connected a CD player into the CD RCA input and powered it on. It seemed to work for a short while and when I turned the volume up and down to see the the VUs works, the power started to clicked off... -
Hi, this is my personal laptop, which the original board (lets call it Board A) blew up PU8700 (TPS51486), making a hole on the board, i had left the laptop at my desk one day with the battery fully charged and didn't touch it for a week, but when i tried to turn it on it didn't
Thought the battery was dead, so i plugged in the charger then tried to power on, the power LED blinked once, charged LED still orange, unplugged the charger, plugged in again and I noticed the "magic smoke" smell, so i unplugged the charger, removed the back cover and saw the blown IC (the "magic...
