White Glue needs to be cleaned off the circuit board. Common issue with these radios. Check for swelled or leaky capacitors. A radio of this age could use new caps anyhow.

The power supply fuse should be next the the ac input plug on the power supply. It should be a long cylinder type fuse, probably a T6.3AH/250V. You will want to replace those caps ASAP

The silver hwite/grey screen means that the LCD panel is not getting the signals, 5vdc from the logic board. Try reseating the connections between the logic board and the LCD panel first.
Also check the power supply caps.

Wont turn on

The problem usually is from low quality or defective "capacitors" on the main circuit board. There are two capacitors in particular on the main board that causes problems with these tv's. You can check for swelled up capacitors or burn marks on the circuit board. You can also purchase an analog tester or ohmmeter and test the capacitors.
If for some reason these caps test to be ok, then test the power inverter.

check out the power supply board! Look for popped capacitors. They either leak or swell up. They are the can shaped things on the board with the plastic coverings on can usually see a swollen cap sticking up over its covering as a telltale sign.

Good luck and be careful

TV wont turn on at all. I have read alot of forum posts about the capacitors. I took off back of TV and nothing appears to be out of order with capacitors or anything in power supply. I am not gettting...

I had the same problem. The power supply had a bad capacitor on the 5.3V output. The value of the cap is 2200uF / 10V. The top of the cap was swelled. With the cap changed the TV now turns on again. I hope this helps.

Screen shuts down after 5 seconds

check the cables. If they are OK, it may be the power supply inside the screen. In some cases it is the capacitor that blows or swells/leaked which indicated it has gone bad.

White screen

dreaded capacitor issue. benq's were famous for it. if you are handy with disassembly and careful you can take it apart and do it yourself. look for any capacitors with rounded tops. i fixed one ... the part is only two dollars or so but it's a good feeling to know you fixed it instead of tossing it.

Benq lcd Displays only white

Most often the all white screen is the result of a missing voltage to the LCD panel. We usually find an open fuse on the panel circuit board. Unfortunately replacing the fuse does not usually fix the problem.
