LG 32le5500 switches on and of, using touch or remote control,Touching the panel on the set the icons light up but nothing moves it from the LG logo screen. Is there anyway to reset this unit or does it need a new main boar? Thanks James

Hi there!
My friend wants me to help him repair his old-real-vintage strong-hammer machine. Well it's only 90% real as the force applied doesn't lift the weight itself but it is measured and it moves a motor that lifts the weight
I am attaching several pictures of the machine.
It basically has 2 sides, left side has- 2 x 220->12+24v transformers
- 2 relays (1 moves motor UP, other moves motor DOWN)
- IGF and breakers for safety
- Logic board. Receives 24AC and recitifies it into DC. Contains a uC (M80C85)

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

kind-a use
But what I just bought will work very well for doing this kind-a thing
What nice about this light box is that it has three light levels
The light box is... -
Hi to all,
power supply received without few elements,FET, transistor and SMD resistor ( someone try to repair it before).
looking for documentation or possible someone can give me a values of mising elements.
I imediately change viper 27 just to start with something. all capacitors are changed by me too. all diodes tested by meter. all fuses tested too, all ok
