check your front & side covers; close them very well .make sure that the two switches of both covers are ok, & lastly if ch is still remaining after all this go & read the fuses at the powerboard & replace the blown fuse with the correct value. thanks

Dco11 got wet, charges but no radio


HI BVanhook,,

You have probably increased damage by trying to power the unit when it is wet. Any time you get electronics wet, you should not apply power when a chance the circuit is wet. This is becasue a form of Electroplating occurs. Metal from one circuit trace will move to another. Heat will build from short circuiting and the circuit will destroy itself.
Disassemble the Radio and Display, dry it throughly. Do not apply any more power until you have thoroughly inspected the circuitry with a magnifying glass to see if any of the Electroplating occured. Clean it up by scratching the short circuits between the traces to clear the connections made by the Electroplating. Good Luck

Lcd benq t705 power button not working


When it have this kind of error is a problem of the powerboard.
Anyway you must open it and look at the all capacitors and if are them inflated, if them are inflated must change them.

But can be a problem with inverters... control the transistors - MOSFET on the powerboard.

Good luck!

LC26AD5E screen goes black after few moments and sometimes almost immediately. Does not switch off onto stanby using remove - have to use top button.


I'd suspect EITHER the Powerboard capacitors failing, opening the case (after switching it off and leaving it for 24 hours to drain charge) and looking at the capacitors to see if any are blown or bulging will confirm this, as will blackening on the board.

Or, the video board is failing. Power getting to board but not making the circuit to light the display, or an associated fault.

Power supply


it is called powerboard, you can buy one at EBAY or another online parts store, to order one you will need your tv model and product code, located in the back of the TV next to the serial number.

Unplug the unit for 1 minute, replug and try again. If it doesn't work the power supply is faulted and it needs professional service.
