My daughter let me have her LG 42" tv. As I am on

  • There are a couple boards as well as a power supply that goes bad in them LG Plasma's quite often.
  • Here are a link to the two different boards in question.
  • Here is a pic of the 2 boards in question. Y on the left and Z on the right (indicated with the red lines) You want to remove the connectors from them two boards that run to the power supply (circled in yellow) and if the TV powers on it is one of them boards. Connect one of the boards and power the TV on. If the TV powers on it is not that board. If it does not power on it is at least that board.
  • If the TV powers on then there is no need to unplug that board again. If it does not power on then you need to unplug that board to properly test the other board (because it could be both boards.
  • Now plug the other board in and turn the TV on. If the TV turns on it is not that board. If it does not then that board is also bad.
  • At this point you should have been able to determine which board IF neither are bad.
  • If neither board is bad then the power supply (top middle board) needs replace. This would be indicated by both boards being unplugged yet the TV still does not power on.

  • OK so now I have explained how and what to test/replace on your TV. Now for some safety information.
  • Them silver bar looking things going across the boards are heat sinks and can carry a possible 500 volts and you touching them can cause you to ground them and serious injury or death can result. I recommend a tech to do this. But you have the steps to diagnose and fix your TV. The choice is yours.
  • Good luck,
Regards, Tony

Hello :i have a bad projection tv Symptom :power

sounds like my 32", its going to be one of three things,
Convergence board,
if it is this you will need to order one online and install it yourself, lots of guides online to help you with this process,
High voltage power supply,
again this can be purchased online and directions are available, if it is the high voltage supply, the tv will act like it wants to come one and maybe click a couple of times
Low voltage supply,
the tv will do nothing, now if the tv does nothing, the low voltage supply isn't the only possibility, but the most likely, check fuses on this one as they are easy

My 64 in mitsubishi tv (9 years old) turns off immediately why? I tried unplugging and it still just turns off

The TV either has a power supply fault or a fault that is shutting the Power supply down. So that there will;be no more damage or indeed a fire. You need to take the unit to a reputable service centre/man and ask for a firm "Quote" for the work to be done.

My W3201C 32" LCD TV made a loud popping noise when I turned it off. Now it will not turn on. No power. No LED light.

That would be your transformer popping and dieing. Usually the popping is followed by a burning smell which is a good indicator that the part is unrecoverable. The cost of the part is variable based on the make and model TV and is usually not too labor intensive to replace. If not under warranty, let the repair gut know that you know what the problem is. Then, ask them to quote the cost of the replacement part and part number. Then ask them to quote you their hourly rate and get a time estimate. Then, google the part number and see if the cost is reasonable.

I have LCD TV (Astar 30") Model # LTV 3001. There is power (Sound) but no Picture... (Back light does not go on)

The back light power is not working or is low. You will need to replace the power supply or get it repair since these service parts are no longer being manufactured.
I service these power supplies.
Let me know if you require further assistance.

Ok, Look, you can do this. Just take care when desolder any electronic part. ( position). mostly in capacitor ( - + location). You can buy a : power supply kit for ctc169 chassis. But maybe don't need replace all parts, just replace 2 small electrolytic capacitor 2.2uf 100v and 39uf 100v and ready...I hope this will help you. Thank you !!
