Hi, I have a Sony kdl-32w653 which blinks 3 times, this tv has an external power supply so I think there is only a main board and inverter board inside it, would a replacement main board fix this? Also just had a quick look and this tv seems quite tricky to get into.

Re: kdl-32w653 blinking 3 times
Had a look at this now but cant get into the thing, have taken out all visible screws but the back wont come off. Looks like the whole back should slide up but i must be missing something.Last edited by duarab1976; 01-24-2014, 11:48 AM. -
Re: kdl-32w653 blinking 3 times
Ok got the back off, there were many clips holding it and a good few broken after i got it off, tried the motherboard with all the parts disconnected and i still get the 3 blinks so assume motherboard fault and have ordered another.Comment

Re: kdl-32w653 blinking 3 times
welcome to the forums, before you go shoot the money gun at it can you upload some clear pics, it could be a blown fuse or a bad cap or something is shorting to ground
when you say all the stuff is disconnected what exactly is disconnected ? inverter, main board, t-con or power supply ?
you should upload pics, do you see any swollen caps on any board ? do u have a multi meter ?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.

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... -
Problem
This is an LG edge LED lit LCD Display. The LEDs are on the bottom edge of the display. There are 2 bars (left and right) Each bar has many LEDs and a 6 pin connector. Each pin drive several LEDs thus is the highest current flow / heat junction. The weak lead free solder gradually fails with thermal expansion/contraction cycling and increases resistance. PSU will compensate up to a point, then when the current is too high, PSU just shut down the backlight causing a dark display. I have even seen one which the connector just fell off as solder points became completely detached.... -
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
