Re: Proscan turns on then screen goes black

Note: this tv has two inverter boards

Re: Proscan turns on then screen goes black

Didn't visually see any bad caps but when I pulled the power supply board off I seen that it looked that all the caps have been replaced (due to solder marks)(I did get this tv used) now after I plug everything back in I can watch the tv for about 3 min each time of unplugging and plugging the board back in then the screen goes black to where you can only see the picture with a flashlight. Any idea of what is going on? I am leaning towards a power supply board but I am still getting the same voltages out to my inverter boards and main...

Re: Proscan turns on then screen goes black

I'm not real savvy on tv repair but like doing things my self, so here is my question (hopefully don't sound to ignornat to tv repair) but could I have any bad caps on the power supply board and still be getting 23.9 volts to the inverter boards?

Re: Proscan turns on then screen goes black

Does anybody know where I can find inverters for cheap? Found 1 for 1 side on eBay but having problems finding the other side. Just hard to believe both sides aren't working.

Re: Proscan turns on then screen goes black

Thanks I read a little bit of the posts on here, the tv was on for a little bit yesterday and I ran a self check and all the bulbs looked to be lighting up (had no weird black lines, fading, or shadows,) now it's back to the same thing comes on them screen goes black, really didn't want to replace the inverters (as I feel this particular tv does not deserve that kinda money put into it) but my end up having to go that route

I am new to this site and a apologize in advance if this has been asked a 100 times. But I have a proscan 42" LCD #42la30h tv and the problem I am having is when I turn the tv on the screen comes on the goes black but can see the picture with a flashlight up close to the screen. All the capacitors visually look good and I am getting 24.9 volts to both my inverter boards from the power supply. So has both of my inverter boards gone bad? I am not to tv repair savvy but would like to save some money from buying a new tv. Thanks
