My Samsung flat screen TV died.

You fail to give us model information and age of this unit.
If all else fails wallyworld has a 60" 1080 on sale for $395.00 at that price it might be cheaper than fixing yours.

Lost Remote Control? Here's a way to help.

So you have lost, or, your remote doesn't work? You can't "Do anything" without it.... Right.... NO Wrong... ALL TV sets have a number, usually about 5 - 6, "Buttons" on the side, front, somewhere. usually close to the "Power ON" switch. Now these "Buttons" will perform nearly all, if not all, of the main functions of your "Remote" They WILL be marked, MENU, +, -, <, >, & OK or ENTER. Now you simply have to depress each button to access the "Functions" you want. One button WILL control the "Function" say Channel, and the <, >, will Go UP & DOWN. This is the same for everything. So one button will make it, say go UP, another will make it,say, go DOWN. Repeated presses on the "Function" Button will scroll through the "Functions" IE: Channel, Brightness/Contrast, Selecting Inputs, once "Selected" another "Button" will move the "Selector" through to the Bottom & another will scroll it back Up, sometimes the ONE button will simply continuously scroll "right around" Of course have a look in your manual... you know that paper thing you shoved away in the cupboard... This will explain it all. ALL TV's and devices that use a "Remote" are ALWAYS able to "Control" the MAIN functions of the unit,via keys on the actual unit itself. So don't despair, just spend a bit of time learning your "Buttons" that way even if the "Remote" does go walkabout, or the batteries go flat, or it just stops working.. well now you can still have complete control.. the only draw back is you will have to get put of your seat to do it. A small price to pay?

Remote not working nor do side buttons respond.

Fault at its main digital board. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts.
In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.

Where is the power button on Panasonic 50" plasma

The "power button", which may be identified merely with a symbol usually is located at the top of the universal remote although some place the power button near the bottom.

My lg mod# 42LV4400-UA tv will not turn on

LG had a serious quality problem with the main board and there is a bad solder joint on all original 42lv4400 and 47lv4400 units.It will manifest the problem either went it gets warmed up and then power down itself or never power up. The red light stays on and the TV does not respond to manual or Remote input.
A factory reset will not fix this problem. It takes a "NEW" main board. The big white label on the back panel has the original manufacture date and LG will send out a factory authorized technician to repair the unit within the first year after that manufacture 800 243 0000 to schedule a home visit to get the repair done.
By the Way, a 42lv4400 main board will not work in a 47lv440 even though they look identical. The reverse is also true.

The TV worked fine on Sunday evening, turned it off the normal way when went to bed. Came down to turn on in the morning and only the red light comes on indicating standby mode. I have unplugged...


There seem to be a problem that is why the television is not coming up and stays stuck on standby mode.

First try to turn on the television using the remote of the television and ensure that the battery of the remote is properly working, you can as well try to push the channel button on the television if the remote does not work.

If it does not come up both by using the remote and pushing the channel button, then it means it is a hardware problem, and that is from inside the unit of the television. Since the standby light comes up, it simply means power is reaching the main panel of the television.

This mainly used to be caused by a faulty or bad capacitor on either the main panel or the power panel of the television.

To check and fix, follow the steps below:

Hallo. I have a Prosonic TV type LC-27M65 that will not switch on. The red control light for remote is on. The yellow light indicator for current is off. Although TV is connected to net for power, the...

It is possible that your TV has encountered a fault in the power section possible a short in the drive power section. hence on powering the power sully working OK is switching the secondary power to the main board but this short is taking in more current than specified. the feedback of this is read by the SM unit to shut off the power to protect the supply. Hence you will have to probe into the sections to find this short, perhaps a HT drive transistor or the HT transformer or capacitors. If will be easier to check the continuity with a meter. Please attemptt only if familiar otherwise take help. Disconnection of the shorting section will switch the power, replace teh component in question. Hope you try. Good day

If you can not get it fixed, I have one of these with a broken LCD screen, that apparently you can not get a replacement for, I would be willing to purchase your broken model and try to marry the two if you feel like selling it.
