Re: Vizio VP50hdtv20a 5 blinks ps board any suggestions?

Well I sat down tonight and worked on the tv some more , I just barely moved the va voltage adjustement and tv fired up with sound , no more blinking on the ps with cn8010 jumper on like it is supposed to be . Tv is working great and still on YAY! not bad for 115$ total investment Im figuring the tv repair guy that had the tv before me ajusted the va voltage and never set it back trying to fix it . The main board was bad still I retried it so I did also still need that too . Im so happy now and thank you everyone that helped...

Well replaced the main board , still got the 5 blinks and nothing, took off that jumper cn8010 and tv powered on , picture is on now everything works but the sound . So leads me to beleive the audio board is shot also . Gonna order one they don't cost that much . Is that what anyone of you would guess? well till audio board comes in I am gonna leave it alone.

Re: Vizio VP50hdtv20a 5 blinks ps board any suggestions?

well for some reason i think its the main board , so I ordered the main board was only $101 to the door. So if that Don't work Ill order the Power Supply board which is $120. I paid 15$ for the tv so if I have to sink 100-220$ into it will still be worth it imo , and not like I can't turn around and sell board if i don't need it or keep as spare cause ya never know Will keep updated so next person that has same problem as me can know what to do .

Re: Vizio VP50hdtv20a 5 blinks ps board any suggestions?

Ok so I started to mess around with the tv again since the wife is getting angry at me since i have had this thing on the kitchen table for past few weeks lol. I took Voltage tests from all the plugs off the ps board and the voltages are under the pins in the diagram I made. One Diagram is for When the TV Turns on Right away before relay clicks off . Other is after the relay clicks off , and the other is just showing what plugs go where . Also for some reason I didnt see that on the ps board it labels what the led blinks mean...

Ok Here are some pics , I have tested some spot that were labeled on the ps board , ones labled were 5v and 12v , some where there when the tv was in on mode and others were there only for the few seconds on turn on . Im still searching for the schematic atm so I could try to test some more.

Vizio VP50hdtv20a 5 blinks ps board any suggestions?

Ok I am working on a Vizio vp50hdtv20a . Tv powers up light stays on in front , relay clicks on then off. Power supply board has green light on it blinks 5 times. I also have noticed on board below the main board (logic) has 3 lights that light up for about 10 seconds from initial turn on. I checked fuses all are good . Even the disc ones and the rectangular smaller ones. I see no caps so far that look bad or anything burned. I think I am gonna start popping caps out of the board and start testing but figured I would come on here first to see if anyone might know of a common problem or even give...
