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.

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

Toshiba 37X3030D TV. Screen fails to light, sound OK.


That'll be the inverter board. It might be the 6632L-0490A made by LG Philips. If it is, you'll find the 2 capacitors have leaked and a bit has blown out of the chip. The inverter board is hidden behind the main board on the 505 model.

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.

Intermient fault. The set comes on and goes off . Tried few capacitors and dried joing but no joy. can u plz help me? Thanks


Normally faulty capacitors are the culprit for this issue. Make sure all bulging or leaking capacitors are replaced. Check also for loose connections or burned parts or parts that have a burned smell while the power is not connected. It could also be a software issue, your sleep timer may not be working but this can be rare. You may want to play with this to test.

It may be the power supply circuit itself that needs replacing. Other parts when faulty may still allow the TV to run. Faulty parts that would let the entire unit over heat or burn out would trigger the shut down.

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.

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