No power tv will not turn on


One of two problems. The first thing this model will have is a convergence problem. Yes it can prevent a no start up in worst cases. If you can remove the back cover do so. You will have to be sure your TV is unplugged of course. You will see where there are two boards on the floor connected with jumper jacks. Remove jumper jack, location number 1516. Plug in the TV. Now power up your TV. The picture tubes should light up and may go out. This is a good sign.If this happens, I would certainly replace the convergence board, in some cases this board is called a signal module. In this case I do not recommend a repair kit. This would be fruitless. Call union electronics and purchase a refurbished convergence board. Upon receiving this board, you will be asked to return your old board and receive a core refund. The number for Union Electronocs is 1 800 648 6657. Have your model number and chassis number with you when you call.The next problem would be a bad small signal board. The test for this one, should be before you open the back is as follows. Leave the TV unplugged for a week or even two. You must really let the capacitors drain. Then plug in the TV and power it up. If you receive a good picture and volume for a few seconds and the TV goes down...you do have a bad signal board. A word of caution here...This board is quite expensive at about $ 290.00 with no core exchange. Thanks for asking and show a few hands of support!

Tip

Flat Screen LCD TV has picture on top half, black on bottom.


You turn on your beautiful LCD flat screen and when it boots up it has a picture on the top but nothing but black on the bottom. What is wrong?

Since the top half of the picture is working we know that the circuits which drive the signal and display are OK. They are the same for the top and bottom.

The difference is there are two YSUS drivers for the unit. One on the top and one on the bottom. They are referred to as the Upper and Lower YSUS drivers. They provide the signal to the display. You have lost the one on the bottom.

Unplug the unit and lay it on a flat padded surface. Remove the rear cover by taking out all the screws around the perimeter. Some screws in the center of the back may have to be removed. They should be obvious.

Once the back is off look on the left side of the unit. There should be separate boards (split top and bottom) which are the YSUS drivers, top and bottom. The boards are only about 1 to 1 and 1/2 inches wide and occupy 1/2 of the space from top to bottom.

You may have to remove the YSUS board, and maybe even a support beam to get the driver board out because the Upper and Lower YSUS boards are usually located under the main YSUS sustain board.

If you go to http://www.encompass.com and input the model number all the parts will be listed. There may also be a service manual available for downloading and you can scroll through the parts to find the Upper YSUS board. In addition the board should have the part number on it.

For Panasonic it generally begins with TNP-XXXXX. Your other option would be to look for the part called "YSUS lower driver" . Order this part and install it and you should have a working set.

I have a tip at http://www.fixya.com/support/r6981868-replace_circuit_board_in_modern_tvs which explains the proper procedure to remove and replace a modern electronic circuit board.

Thanks for using FixYa and for the great rating. Please consider a testimonial. Thank you.

Have lg du-42py10x plasma powers up but no picture no sound dark screen with white dots


if you have checked the activity of the outlet and the status of the TV (turned on or off) you may want to get it check through an LG authorized repair center, the issue could be the switchboard that channels the video and audio.

42" haier plasma with sound and black screen!


Usually you have to be a certified technician of the manufacturer to order and receive those parts. It comes down to insurance reasons because if you were to install them yourself and the TV burned the house down and you were to perish, the company would be liable. As frustrating as it is, you will likely not get the parts. Are you saying that Haier will not provide a service technician for an out of warranty repair or at least point you in the right direction? That's poor customer service and I would think twice about purchasing from them again.

LG 42PX3RVC Lost Picture


Hi there!
Ysus and Zsus Boards are normally sold as a kit(about 39 - 50 US$). If you think you are able to remember where all panels and screws are removed and replaced, then it would probably be cheaper to do yourself. On the other hand you may be throwing money after money if it is a power supply fault. I would start by checking the component which exploded and its location. That way you will know where to start. If in doubt rather refer to service technician. Please note: High Voltages are present so do unplug before inspecting or removing the cover. Also do not put the screen on its face, it may damage. Always in upright position. Good Luck, JUS004
