I changed the led strips on my Hitachi 32 inch.
The TV is now ok since I have already replaced any capacitors that needed replacing.
I have also bought a spare set of LED strips for the tv also.
I want to be able to replace singular LED's in the LED strips if I need to, but I am not sure what value LED package to buy from Ebay in the UK.
The LED strips I bought were:
Replacement Backlight Array LED Strip Bar For Hitachi 32HB6J61U 32HBT41U 32" TV
On ebay I have a choice of singular LED's with voltage and colour temperature:
Voltage choices: 3V, with temperature choices:
3000K
4000K
6500K
or 6V to 6.2V, Colour temperature 12000-16000K (cool white)
or 3V to 3.7V, 12000-15000K (cool white).
My Caliper measures the LED's at ~ 3.48mm x 2.63 mm.
There are most likely other choices, if I look more.
Also, I am new to SMD soldering and usually only used a normal soldering iron with leaded solder, though I have unleaded. I also have a hot air gun I haven't used.
My questions are:
1. What voltage and temperature rating of LED should I buy to match the ones in my Hitachi TV?
2.What type of solder should I use, soldering wire, or paste with the hot air?
3. Should I use an iron or hot air?
