In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.

Fault in the main power supply regulator board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts.

It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.

Tv repeatedly turns on & off by itself


Given the age of that unit, It may not be possible to get parts for the unit. The problem you are experiencing sounds like a poor connection on either the receiver for the remote or the main board power unit.

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.

My toshiba problem.


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

Our Son hit a plastic ball into the face of our new Toshiba 40RV52U LCD display. We now have an area that looks like a splat and a hole in the picture. Is it possible to repair or replace the LCD screen?...


Hi,
unfortunately it can't be repaired the entire panel will need to be replaced, most times the cost of the panel is as much or more then the cost of the tv. My son broke our 42" lcd after had it for only 3 weeks! Not covered under warranty...we had to replace tv. FYI there are companies that sell a clear protective screen for LCDs I bought one and it works great! One such website is www.tvarmor.com but you can google and find alternatives.

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
