Top 20 Pioneer PDP-4270HD 42 in. Plasma Television Questions & Answers

Main system control memory IC fault. This is a very small IC; have 8 solder terminals, and can be located very near to the main system control-chroma IC. Check and replace it. Be sure to replace it with the same number printed on it; in all respect. Otherwise, it won't go. http://electronicshelponline.blogspot.com/ Before replacing it, try a reset to this set, and then check. There are two methods to reset TVs. The first is simple to do; a Hard Reset. The other is somewhat skilled; is a Factory Reset (System Reset). To make it a hard reset, just unplug the TV from AC mains wall socket, and re-plug it back after 15 minutes or so. If you do this by overnight is better. This procedure will make it a hard reset. If you want to make it a system reset [Factory Reset]; you have to enter its service mode option, and select the factory reset option. If you wish to get some details; check the site linked here.

got same problem the LG sound plate works with bluetoth mode but don't not detect the pioneer tv set..

1. if you have something else that you can test the optical wire on. do that first. dvd player etc... if the test item works, it's the sound bar (or a setting in the sound bar.) 2. check the audio settings on your t.v. make sure it's set to output to optical. 3. replace the wire. if none of these solve the problem, the t.v.'s optical output may be bad.

The main board fault. Contact the authorized service centre for Olevia. Gopakumar Gopalan Google

A few steps to take to narrow down issue:1. With sound all the way off do you hear the buzz?2. If no buzz that way try the rear inputs with a DVD etc to see if same issue.If the buzz is there with no sound (turned all the way down) and via rear inputs you have a transformer (most common area is power supply) that is vibrating hard enough to create the sound or buzz.Only two ways if that is the case to deal with it---replace the board it is coming from (have seen brand new sets with this) or in some cases I have been able to locate the offending part and apply hot glue to it and stop the buzz.SD TECH

Unless it has a hookup for external speakers do not do it---speakers must match inpedance of original speakers, wrong speakers can result in damage to audio circuit of set, cause reduced sound levels etc.A inexpensive surround sound system might be a option......

Try restting it by unplugging the tv for a few mins and it should rest to original factory default settings but leave it unplugged 10-15 mins to be sure.

Swens, not positive what your issue is. But, give a company named ShopJimmy.com a try for replacement parts. I have included a link to your model page from their site. Hope that helps!

Hello,

Problem is in either power supply or the Y-Sustain board.

The Y-Sustain is a relatively large board out of which go connections to the side of the display; it's therefore closer to either the left or the right side of the display, has at least one rather large heat sink on it and fat power cables connecting it to the main power supply.

Often there are fuses on that board - one or more.

if they are blown you can try to replace them, but expect them to blow again - usually the whole board needs to be replaced.
Hoping that will help out in solving the problem...

Change the resolution on the cable box or satellite box, witch ever you have. A set by itself cannot change the resolution, if the cable is giving you 720p, that's what you'll see for that station. All stations do not transmit in HD. The best picture is only as good as they're giving you.

Hello,

Normal 0 false false false MicrosoftInternetExplorer4 /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-parent:""; mso-padding-alt:0in 5.4pt 0in 5.4pt; mso-para-margin:0in; mso-para-margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:10.0pt; font-family:"Times New Roman"; mso-ansi-language:#0400; mso-fareast-language:#0400; mso-bidi-language:#0400;} A common problem for these is bad capacitors in the power supply, Remove the back from your Tv and look at the power supply on the left hand side.

You will see roughly around 9 x capacitors that are bulged / domed shaped on top usually these are valued at 3300uf 10V any that have bulged or leaked a brown like substance should be changed.
This will cure the problem as they overheat being sat next to a heatsink that gets very hot!
Try and change them for the same 3300uf but a higher voltage.
Hope this helps

Try this! There should be a power button on the bottom of the panel that has to be depressed for the television to power on. It is the main power supply button and without it there is no power going into the TV.

IF you haven't replaced the batteries it may just be the age of the remote although in good condition to the eyes, maybe you should consider getting a universal remote, it comes with a manual and a list of codes and instructions on how to program it on your TV.

Hello. The six flashes indicates that one of the circuit boards has a fault in it and needs to be replaced. Generally the first place to look is the x-sus board and the y-sus board. Regards, Joe

You need a firmware upgrade that has to be done by a tech onsite. I've done many of them. 12 Blue blinks is a TVGuide download trouble and doesn't hurt the set but a firmware update should solve it. If it occurs again after that you need the Main Assy replaced but make sure the firmware is updated on that also.
Problem will go away
Hope this helps

YOU CAN ONLY GET 5.1 FROM THE OPTICAL OUTPUT ON THE SKY BOX NOT THE HDMI
SO CONNECT YOUR SKY BOX OPTICAL TO TV OPTICAL

PLZ LET ME KNOW IF THIS HELPS

i have the same problem. Has anyone found a fix?

Remove the case, look for a fan, vacuum the main board and all case vents. ..

Question edited for clarity. Great question Madeleine. The ones with Screen Saver and Audio are in Preview Mode. If you want to watch them, you have to subscribe. It is a tactic to get you hooked and get you to pay. Sometimes they will give you a couple of minutes of video and audio at the beginning of a programme. It isn't a television issue, it is your cable provider and a sales technique. ..
