      Do have a question myself. Any info on what ZD5502 is? Just in case I have to replace it myself, I have not found what the value of it should be. all i know it's a zener, but Voltage and rating ??

          Tomm66, do you have any idea what's going on with the voltages , would love to be able to fix this instead of just replacing the yboard, but well out of my depth need some expert help

            Sorry I really don't. I haven't worked on one of these for a while.

              Not sure if I should be posting this question on an old thread but here it goes, I have just acquired one of these (samsung PS50Q96HD) which has 'sound but no picture'. I've been reading previous threads and the attached pdf test/repair guide and found the top buffer chip short (no suprises there based on other posts).

              When checking the YSUS, Q5500, Q5302, Q5303, Q5304 & Q5306 tested short while in circuit but after removing them only Q5302 (88N30W) tests as short, the rest test fine. What do you think my chances would be if I just replace the one blown FET and the buffer chip? (and C5300 and C5709 caps) As far as I can tell the other bits included in the repair kits are testing OK. Being a cruddy old set that doesn't seem to be too popular I don't really want to spend much £ on it, has anyone ever tried this? Thanks in advance

                TCL 55S425 few horizontal lines, potential failure on both side of panel/buffer board

                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

                Vizio e601i-A3 - Has Sound and Display, But No Backlight - Bad Power Supply Board or Bad LED Bulbs ?
                by Tynan Dill
                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.

                Assuming...

                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....

                by m1ch43lzm
                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...

                LG OLED77G1PUA - No Video / Audio after a TCON Board change and Software Update
                by Hakuu
                Hi There,

                This TV was auto switching off after few seconds with some vertical lines on the screen, so got a new TCON board and replaced it.

                After replacing the TCON board it was working fine and i set it up with everything, used for few hours, then had the bright idea to update the software on it. During the update process, TV switched off and now no audio or video. No relay switch sound.

                More Details

                TV Model - LG OLED77G1PUA

                Got the same exact TCON board from TVPartsToday and replaced it. But didnt transfer the EPPROM data (didnt...
