Having problems with your Flat Panel Televisions ?

Hi, can you help me with this TV please. Hi, I have a Olevia 232-T11 LCD TV. First my TV wouldn't turn and the blue light just stayed on. I replaced the power supply board and now my TV turns on and the screen lights up but I get no picture or sound. The slave backlight inverter board has a blue light when you turn the TV on but goes away shortly after. The screen stays on but I have no sound or can't control the channel, volume or source button. Please help.



Answers :

If the tv is not coming on but there is no picture or sound then it is a 100% guarantee that its a problem with the audio/video main board of the tv. I am sure that replacing the same would resolve the problem. Please get me the part number that is printed on the board so that I can find you a replacement.

HI,the main board of your TV is not working.

check points.

1.test the 5 volts supply of the main board use a multitester to measure the voltage.
2.re tighten the terminal connectors/socket of wirings from the power supply to the mainboard
3.if the supply of 5 volts is present check for an open surface mount fuse at the mainboard they are labelled as f1,f2 etc.jumper it if you found any.
4.look for a reset button at the mainboard press the switch while the power is on and the TV will work again.
5.If the tuner of your TV is detachable make sure that that it is properly inserted to tha socket.

Try all this solution and let me hear if it works good luck!

I have a LT37HVS Olevia flat-screen that has a similar problem to one of the posts. I had the same blue standby type light on the front that stays lit, but turning it on just makes this light blink, and no display. I did as the posts here sugested, peeled it apart and manually inspected all of the capacitors. To my dismay I haven't seen one yet that looks bloated or leaky. I have inspected the main power supply board, both display boards and the main board. There were a few capacitors that


If turning it on makes the light blink then its a clear case of open circuit.. Honestly there are lots of components like diodes, fuses, transistors etc., and either of them if shorted create an open circuit. I do not think this is a capacitor proble ... Olevia LT37HVS 37 in. LCD HDTV
