I am changing a bunch of capacitors on a power board in my 47pfl7403d/f7 & cannot budge any solder. I've tried adding new solder with no luck. My Hako iron is at 750. Thanks for any help.

Re: Can't Melt Solder on Power Board
A small tip don´t have enough power to heat a big surface . Do you have a heat gun ? if so you must heat the whole area before using the iron . Then put some new lead solder to make it easier . -
Re: Can't Melt Solder on Power Board
Dont solder with a heatgun , you might destroy other parts.
You need a good solder iron. 85W solder iron is more then enough to desolder capacitors.
You probably need a bigger tip otherwise the board will take all the heat and the solder wont melt....I only repair Panasonic plasma tv's! Currently owning a TX-P55VT50 and still searching for a ZT60!

Re: Can't Melt Solder on Power Board

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.

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.... -
This is a guide that I am writing for helping others to replace their MEC1503 EC chip if it breaks (or to get around an inconvenient prompt to the BIOS). This forum has been extremely helpful to me so I would like to contribute to help others. I will tell you right now that this task is very difficult to do. You MUST have experience and tools to do precision micro-soldering, BGA reballing, trace repair, and general laptop repair skills.
There are some specialty tools needed to do this task. The replacement MEC1503 chips can be acquired from Aliexpress. Do not buy the bare chips as... -
Hello.
I have a soldering station, 862D+, and every time the hot air gun is on, even if it is just cooling off, the soldering iron controller stops controlling. Let me explain what has happened so far, as it took a while to get to this.
First, the switch that turns on the hot air gun started to fail, the light came on, but temp never rose, I would have to switch it multiple time to get the gun to start heating, this was due to the contact inside being carbonized. I opened the switch up, clean the contacts, and it would work fin for a while until carbonized again. So, I ordered a switch... -
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...
