Sylvania 6842PE 42 in. HD-Ready Plasma Television - Page 2 - Answered Questions & Fixed issues

the 1inch black line is either a buffer board gone bad or the ribbon cable from the plasma screen to the buffer board, the snowy picture could be many things, including y-sus, xsus or tuner boards

Hello - The fact is that your TV, as a HDTV ready device, is really a display monitor that does not contain any TV tuner. There is no place to attach your coax TV connector.

To view TV on the unit you would have to either subscribe to cable or satellite TV service or buy yourself an external TV tuner such as listed HERE (I'm not recommending this tuner just showing the kind of device you would need.)

Regards and thank you for using Fix Ya.

Hello; This is a common problem. There is a blue disk shaped capacitor that has shorted. It was made by Panasonic who famous for crappy parts. It is about 3/8 " in diameter and 3/32 " thick roughly. I think this is a 2200 pf @ 2KV but not sure without going into my notes. If you send me the board , I can replace this part but without warranty. I will require $45 cash or postal MO to cover labor part and return shipping. Call me at J D Electronics 207 998 5687 M-F 9-5 only John

Hopefully only your power supply is to blame. Then you can repair it or get it repaired for a little more than $150 or get it replaced for about twice as much plus the cost of labor. If you or a repair person start testing the boards and see that one or more of them have also failed then the cost of parts and labor will go up. It looks like Encompass Parts has parts still available for this television and the power supply is $194.

Hello, hopefully you got this resolved already, but if not, here are some quick and simple steps to go through. Follow the link below, and it will walk you through a power scan, so that the remote can find the correct code for the tv. I hope that this information helps!

I had a similar problem with my 42 in Philips LCD HDTV.

Here was the problem. My Power Supply Board had several bad capacitors. I opened my TV (warranty was expired of course) and found four bulged capacitors on the PSB. Many major electronics companies Philips/Magnavox, Sony, Panasonic, and others were sold capacitors that failed in 2-5 years instead of 10-20. The capacitors fail prematurely due to a lack of preservatives. Unfortunately, they were installed in all sorts of devices and cause a wide range of failure problems.

Here are some options for you.

1. Have it fixed by a professional $$$$$$$??????? (Is it under warranty?)

2. Open your TV and find PSB. (The board that the power cord plugs into) Check for faulty caps. If you find some (bulged or leaking) bad caps replace the entire board. The entire board costs around $250 right now because they are in high demand right now. They can be found at tv-part.com but supplies are limited. I would definitely shop around though.

3. Remove and then replace individual faulty caps. This takes some soldering skill.

Caps are inexpensive and if you can take care of it yourself it will save you hundreds.

This may be your problem. If you determine that it might be.

I have a Tip/How TO tutorial on this site that may also help. It gives step by step instructions for replacing caps on PSB #715t2432-2. If this is your board you are in luck. Here is the Link: Fixing the Philips Turns/shuts off on its own problem. I'm working on uploading pictures to help guide people though the process as well. Let me know if I can do anything to help.

Hope this helps and if it does please rate it accordingly. Good luck.

if your storing this set ideally in the original box would be a good start never on a concrete floor from my experience and try these temp guidlines -4oF to 113oF (-20oC to 45oC) when you remove this from storage allow it to reach room temp before using it 12 hrs should do it hope this helps

Hi,
The power board has a fault or it is sensing a fault from another circuit and shutting down. If you have an electronics background and some test equipment I can walk you through what to test. Or you can take it to your local TV service center.

I have the same exact TV and the same exact problem it seems pretty popular, but there also seem to be different answers to similar questions. Some sort of problem with the Power Supply Unit. Maybe a blown fuse or bad capacitor, thats what i am about to check for, ill be coming back here in hope of finding a solution.

This TV doesn't have a tuner and thus no RF (coax) input. It should be connected to a set top box by component, composite or S-video cables. Component video (with three RCA video plugs on each end) will provide the best signal (a separate cable with two plugs on each end carries the audio).

I wish that I could be of more help.

did you have a surge protector? if not then you probably burned out a resistor, what its doing is performing a system check while its blinking then finding a fault and shutting down as to not cause a fire

Try the S-video port. works for me! and MOST laptops already have the s-video port in them.

*To Manually program the AT&T universal remote control to your

Note: After you program the tv make sure to press the ATT button. then now check all the function of the remote. Follow the instruction and it will work. If you press the power button the TV and ATT Recievier will turn on and off at the same time

Thanks for using Fixya.

I had the same problem. My nephew gave me this set after it quit working at the Gym where his wife was working. They were going to junk it but I asked if I could try and fix it.
The capacitor C2250 was definately blown and easy to spot so I did some searching and found a replacement from an online electronics supplier that didn't require me to buy 200+ as Digitech wanted. Anyway I replaced the Cap and it still didn't work so I started looking and testing components again and found that the Diode D2250 was bad so replaced it as well and now the set works fine. Maybe this is what is wrong with your's and others as well.
It made sense for me to check the diode as it is right next to the cap that blew. https://www.mouser.com for the Cap and http://www.slelectronics.net/ for the Diode.
The specs for the Cap/ CERAMIC CAP. B K 1500pF/1KV
The specs for the Diode/ SCHOTTKY BARRIER DIODE YG123S15


Hope this helps

its the problem of overheating in the power supply board of the TV.on the power supply board of the tv there are few capacitors and IC.any of this ic is got short or may be weak.so due to this when you start the TV the current passes from electric outlet to the power supply board of TV.but when the current passes from that weak/faulty part at that time current gets stopped or slow and the board overheats and TV shuts off. this is a common problem faced by many other users too.the possible option to solve this issue is to check the power supply board by a meter and continuity tester and replace the faulty component on the board which is short due to which power supply board is getting overheated.its bit technical job but yes its not at all a costly repair to do or get it done by the technician. for required parts it can be easily available from local electronic hardware shop.] This will help. Thanks please keep updated.please please do rate the solution positively .thank you for using fixya

You simply need an "F" connector to "Belling-Lee" converter. about $4.00. At any Radio Shack, Antenna shop. This screw onto the end of the existing antenna connection & makes it so you can plug it into the Socket at back of set.
I have included a link that has a picture.

Ur LCD inverter board it dead.Replaced this board to get picture back.It usally a long board. Tries Shopjimmy.com,Ebay.com to buy this board part.

Try to format it first and scan for virus. Secondly, see if the windows you are running is compatible with your mp3

Try website 1-800-Remotes Factory Original to buy an original remote.

I have been having the same issue. I unplug the TV for 10 minutes and it usually works fine. I moves all of my A/V plugs to a single power strip and that helped a lot. Since then, the TV went into protection mode only once in 2 weeks. Next, I will use a power strip that includes the cable protection.
