SOURCE: RE: Vizio P42ED Plasma TV

Just took the unit apart recently haven't tested the heat sinks and I don't see any error codes. None of the video inputs work but I do get sound from the RF input audio. I have not connected anything to the RF video input for actual video but will try. Right now I'm guessing it is the main input video board but the part nunber on the board does not match that of the parts distributor.

SOURCE: Samsung Plasma TV - picture has 6 sections of horizontal lines

All I can say is when you watch T.V. the plasmas run off of plasma gas and when you leave something on for so long it burns in the screen. I have the same T.V. and when watching like the weather channel it leaves lines but they go away. If yours are permanent then you can't do anything, but it may help if you go on your remote and go to "menu" then look for "setup" and scroll down with the arrows on your remote. Look for "screen burn protection" and select "white screen". This will make your whole screen white and it may take out the lines. If you let it sit white it won't hurt it. All one color won't hurt, the only thing that hurts is like bright white lines in front of a dark background. Just give your T.V. a break from time to time ESPECIALLY ON VIDEO GAMES. T.V. shows that are HD usually have their channel icons that move or are very dim and they won't hurt. Just go to what I told you and let it sit about 20 minutes, if that doesn't help, then the T.V. you have i believe comes with a 2-year standard warranty and if it's under warranty take it back if you have the reciept. If no reciept then call 1-800-SAMSUNG.

It's a pretty common problem. The no picture but sound problem is usually the y board. I've replaced 2 on mine now. The 680uf 35V capacitors usually are bulging because one of the power transistors went and took them out. This has happened to both of the y boards I had. One time the failing y board took out the buffer boards too, and once it did not. The fix is super simple and anyone with even the most rudimentary knowledge of computers or electronics can do the labor yourself. You should do the simple stuff first by just doing a quick test with a multimeter. Just check the power coming to the y board. After that you can just remove the y board by removing 3 cables and like 3 screws. Plug in the new board and it's done! You can source the parts from a place like shopjimmy or discount merchant. 3 boards were like 200 bucks. 1 board is like 100 bucks. Labor took me 15min. Think about that the next time an electronics repair place charges you 1000 dollars. Of course they check everything (Yeah right) and warranty their work (I don't) but if you check the service manual it states that this is the most common repair. Look for the Canadian manual online. Hope this helps!

I hate to tell you this but here it goes anyway
just about all products that come from china are made with inferer parts and will not last long. so if it lasted that long you did good. just go and buy another one for there is no parts for just about any tv and if you do find them they might cost more than you can buy a new tv for

My samsung tv model number ln40a55op3f 8. havin troubles getting it to turn on...it wont turn on for like five min, then it will just keep turnin itself on and off until we unplug it...you never see...


The tv have a dying power supply board,that the board where the tv power a/c cord plug into it.U have all the tools and the understanding of basic electronic and also can do basic soldering works too?Yes,take all the Philip screws out of the tv backcover,take the tv aparts and now check the tv power supply board carefully for dying and soon to be dead components parts that are call capacitors.These dying and soon to be dead components capacitors parts are alway bulges up or puffing up onto it tops.These capacitors components parts are dying and soon to be dead must be all to be replaced.After u replacing all the defective capacitors components parts.Now the tv power supply board will be fixed and working correctly again and the tv will not have anymore power delaying like about 5 mins. or flashing LED power light indication,require unplug,replug again awhile before it will turn on.Or tries websites like Shopjimmy.com,Ebay.com to buy a whole new refurbish tv power supply board for the replacement.

Samsung lnt4042hx/xaa 40in lcd tv wont turn on


I concur with Lightnbaby.... had same problem... my TV LNT4042HX/XAA took 10 min to start sometimes... the capacitors on the power supply board had bubbles on top 4 of them all 10/1000Uf. Samsung wanted to charge $220+ to have a guy come out and fix. J&J parts (samsung vendor) wanted $108 for a new board. I replaced the 4 capacitors for $4.68 and the TV works fine now!!!!!
