50 inch lg won't power on


Hi,

The problem could be just a few bad capacitors on the Power Supply, there could be a bad capacitor on the Y board if its bad it needs to be replaced with the buffers together
If you want to attempt the repair yourself you can do a visual of the power board caps will appear swollen on top.
The ones you are looking for are located almost center bottom of the power board,Usually I can see them clearly with the back on simply shining a light into the back through the holes
If otherwise you have to change the whole power supply board Power supply board just die.It can be dead at anytimes.Tries websites Shopjimmy.com,Ebay.com to buy a refurbish power supply board for the replacement.

I hope this will help in solving the problem...

Hello,
power supply board is dead, u know basic electronics' and soldering? Most of the times, the power supply board just have dead leakages gases capacitors.These capacitors always bulges up on it top,or puff up on it top.Replaced these gases leakages capacitors will get your TV power stable,and work again.Or tries websites like Shopjimmy.com,Ebay.com to buy a whole refurbish power supply board for the replacement.

Hoping that this will help to solve the problem...

Power supply


Hello,

I hope I can help you with your issue,


Either the power supply has an issue , or you have a bad buffer board and Ysus scan board or both.red light indicating may mean power supply , 7 blinks the buffers and y board.
A repairman will usually just order the boards and you will spend about $550-$600 on the power supply or over $700 probably around $850 if its the Y board and buffers.


It could be just a few bad capacitors on the Power Supply, there could be a bad capacitor on the Y board if its bad it needs to be replaced with the buffers together
If you want to attempt the repair yourself you can do a visual of the power board caps will appear swollen on top.
The ones you are looking for are located almost center bottom of the power board,Usually I can see them clearly with the back on simply shining a light into the back through the holes


With the back removed you will see a few circuit boards the upper one (ac cord runs to it through a small board) is the power supply, it has a lot of capacitors on it (cylindrical standing straight up soldered in and marked on the sides with the positive/negative sides and uf and Volts values)
Philips uses 2200uf or 3300uf at 35Volts rating capacitors, they cost about 1dollar-2dollar each

The power board and back unscrew with a torx bit and screwdriver size 10 and 15 , if you do not know how to desolder and resolder then do not attempt this as you may damage the TV more than fix it.
We do not recommend do it yourself, but depending on your knowledge and technical ability you may be able to.
You can replace the whole power supply,

Hope this help in solving the problem.....

Techwood plasma twp 4210 broke


First make sure to hit the menu button on the TV's remote and if nothing is there then friend while the set is on turn a bright flashlight on and shine at angle into the set push the TV menu button if you can see a image then your back light is not working.
You can also check the transformers they are close to were the wires plug into the panel, make sure all transformers read the same amount of resistance if not you have found a bad one. Now you will have to check to see if the power supply is sending 24v to the backlight, if not the power supply is bad. Cost backlights around 150.00 and power supplies around 100.00. Well this should help you friend.
