Removing stand from a lg 42lc7d - Toshiba REGZA 52RV530U LCD TV

The power on problem is a cap in the power on circuit. The loss of signal for an areal is delayed. Nothing you can for DIY.It needs repair shop visit.

first you need to remove old bulb there is model no menstion on the top side.please check and replace with same no.

1- check all the cables that are hooked up to the TV 2- try to get audio to and external speakers or home theater (to check the sound card). 3- if the step # 2 don't work either you have a bad sound board on your TV. 4- opn the TV try t get the part # of the board, and replace it

The screws are usually centred in the lower middle part on the rear of the TV, there will be four deep set coutersunk holes where the screws can be found. The stand is fixed to a pedestal arrangement which fits to the underside of the TV.

Most likely the power supply board.

Lie the tv down on a bed and unscrew the back. Its only about 9 screws around the edge and look at the power board, on the left, see if theres any burn marks.

I have a brand new board I bought the other day for the same issue but before I replaced it, stupidly, I checked with LG and turns out mine is still under warranty so I'm stuck with a new board.

Let me know if you want it. I'll match any price you can find online.

not sure what you're referring to as a "main board", but heres the LCD Control Board for the TV

I have broken Screen how or where can i replace it? (model 42lc7d)

There are some inductors that are out of spec. LG's original SB said to replace some of these with a jumper, but it only lasted a couple months.

You need to have the Total Main Assy replaced.
