Question about Toshiba 40RV525U 40 in. LCD TV

Open Question

My Toshiba 40rv52u is freezing and fading out. It has had problems in the past where the screen would suddenly start going dark, but we could just turn it off and then on and it would be fine. That

We've had it for about 4 years, bought at BJ's Wholesale Club. It's hooked up to multiple gaming systems as well as a BluRay and a stereo system.

SOURCE: Toshiba TV fails to recognize HDMI input

If the tv does all those symptoms but after some seconds the tv works and stays doing the job. THen the tv has a slow microprocessor to recognice the different resolutions or video inputs.

But if the tv cannot do anything and stay aout of signal forever. send the tv to the waranty. (no waranty? you have to use the component input instead to have digital signal reproduced

You may have bad T-CON board, try cooling it with small fan blowing on the vents of the TV.

Breaking down after 3 years is about right for LCD TV. It sounds like the T-CON board has gone out. Does the on screen menu look normal?
Learn about failed T-CON/LCD panel here and also read my guide to understand more.

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.

If it has Windows 7 on it there should be an option to dim the screen. Go to the Start menu and click Control Panel.

Click on the Power Settings icon. It should be in there on the left.

Toshiba 40rv52u remote control


If just using one remote to try have it tested----many digital cameras in a dim light will react with a flash on the display screen when remote is pointed at them and buttons pressed.

Also try putting remote against remote receiver lens on front of set--if it reacts close up---the remote receiver in the set is bad---can be same if no reaction at all.

Either the remote or the receiver---one or the other.

A last thought here is some sets (read owner manual) have a feature to lock out the remote which can be engaged by accident.

There's 4 horizontal white tiny lines appear on screen to make the picture become 4 equal parts from top to bottom with many horizontal lines. My TV is Toshiba Lcd(40RV52U)


You have failure/weakening in the vertical section , the retrace lines appear due to the change in the freq.
Check out small value capacitors in this section. confirm by shorting parallel with the right polarity. Unless you are familiar with electronics please do not attempt unless with help. the fault is not very serious and could be attended with low expense.
