Techwood PLR85 400 watt home theatre

I've searched around everywhere and cant find much infomation about this or a similar problem. I recently got this from a friend as he was upgrading, and my reciever had just bit the dust. It worked perfect for 1 week and now last week it mysteriously shuts off after a random amount of time. I have to unplug it sometimes for only 5sec, other times it takes half a day before it will turn on again. The green stand-by light will turn on but the red power button will not show up. Hopefully someone has some suggestions. Thanks in advance.

    I have had my plr85 for about for about 7 years and it has worked perfect up until about 5 months ago. The green stand by light comes on but it will not power on. I unplug the unit for a while and even hit the reset button (it worked fine the last few months, until now.)

SOURCE: Problem With Sound

THE SOLUTION KINDLY POSTED BY MARK TO A PREVIOUS PROBLEM SHOULD FIX THE SOUND ON THIS ONE AS IT WOULD APPEAR THAT THERE ARE INHERENT PROBLEMS WITH THIS MODEL AND THE SOUND OUTPUT Problem:posted by johnny 5 on Sep 02, 2006Report abuse Have had this sys for about 2 years and recently moved it to another room but when re-installed it would only play through the headphones. Moved it back to its original position but it hasn't corrected the problem. Best Solutionposted on Nov 19, 2006 By Mark140872 Rank: Not rated Rating: 0%, 0 votes Hi I've just fixed this problem on my DAV S400. It's down to dry joints on the Amp PCB. Very simple to fix if you know how to works a screwdriver and soldering iron! Take the cover off and with the back of the unit facing you, you'll see teh amp PCB in the left hand corner to the back. At this time its the wrong way up to fix it so you'll have to remove the Ariel connection box and the speaker connection PCB both are very easy to do. Lay these out of harms way but do not disconnect any of their ribbon cables as its not needed. Now you can unscrew the amp PCB which is bellow both boards you have just removed. Disconnect the phono wire from the PCB (keep a note of that) and disconnect the power lead to the PCB on the right. Up turn the PCB and remove the copper heat sheild. You should now find the dry joints. The phono plug you just disconnected fits into a multi socket on the PCB. This will probably be loose or have more than one dry joint. Re-solder all these making sure not to link any together. Now find the large brown capacitor and check these joints and if needed re-solder. Check for any other dry joints while at this stage if any look slightly poor give them a quick dab with the soldering iron but make sure you don't fry a chip!!. Re-assembele remebering to reconnect the phono wire. I allways check before putting the case back on. This worked for my S400 after my 18 month old got hold of it. Good luck! Thank you for rating this solution.

SOURCE: No power

It sounds like the backlight or an inverter board on the television may have failed. Check your warranty status on the television to see if you can get it repaired by the manufacturer for free.

SOURCE: I have a 50" philips plasma , shuts off and blinks red light 2 and 7 times Y main board module problem?

LOL! OMG! I have solved this problem for now. This is what worked for me. First off relax and don't think you need expensive technicians, and from blogs I read it's obvious that Phillips thinks they got their money so your waranty has expried and to bad for you, they don't care.

My problem and the run down. Bought a 50 inch plasma Phillips TV from BJ's Wholesale back in 2006 for about $1,700.00. Note I went o BJ's website to check out the Tv's as I have experienced problems and it looks to me the entire brand of Phillips is not even being sold their anymore. Ha, go figure.

Just this year early 2009, after having about three years I would watch HD cable and at times a click noise would occur where it even clicked the stereo amplifier where my surround sound audio would click as well with the tv, it would appear to go in silence, picture would go balc for about 10 seconds and go back on. This means from what I see later is that your blinking red lightb issue will be coming shortly in the future. It to me is a warning that if you are at that stage, expect to become a victim of the red light district. If this is the stage you are in, and it will still turn on and off ok, and your under warranty, make the complaint immediatly.

Then just 5 days ago, I tried to turn television on and it clicked as if it was going on and screen didn't show anything, and I got a 4 rapid flashing red lights a pause in flashing then 4 flashing red lights.

I googled these very blogs, check them all out as their are different ones and I have a 50 inch and even though the blog I took as a reference was one who had a Phillips at 42 inches etc, or different sizes it may not matter, look at flashing red light problems with all HD plasmas that are Phillips.

I have to give credit to a blogger by the screen name of Doug Mohr. Let me eloborate what his idea was and what I experienced to solve the issue.

It appears to me before all thse techs or electrical guys and TV repair men say they will fix your tv for the price in which you pretty much paid for it, STOP! Wait a minute. What if I told you you may be able to fix it for about $5.00 or $10.00. It reminds me of car mechanics that when my Mercedes shaked in idle position the dealers would be like hey you need to get a new timing belt, or a sensor, etc when all you really need is new spark plugs. Well isn't spark plugs cheaper? Yes indeed and it works fine.

Well, credit to Doug Mohr I went to my garage and looked for an older PC connection to an old computer of mine that was replaced with a new one. Apparently the same sort of connection to power up your computer is the same as the plug to your television. As soon as I saw that on a blog I went to replace the power cord.

The power cord to my old computer Dell from like 2003, looked as if the three little holes that plug into TV were smaller then the actual Phillips connection to TV, but only a little. I realized that it fir into the TV in back perfectly. I then pluged it in and damn it, it still had flashing red lights again. When it did it it again communicated to my receiver for audio surround sound which my barnd is Sony and it shut down including the volume was on only 10 seconds with no picture. So I turned off the receiver for audio, and unplugged with old PC Connecter to TV, waited another 15 seconds, and sure enough I plugged in as if I let it fail once however I may have done what is known as cycling my TV and new plug letting the TV understand that the cord is different. Try a few times. So TV on second attempt withoutr turning power on was plugged in and their was no light blinking anymore. I gave it 10 seconds and it didn't turn flashing red like it does even if you don't power it yet. So, I turned on TV and the picture showed, and then put on my audio reciever and it worked great back to normal.
Not everyone has extra PC cords lingering around, however Doug says you can pick them up for like $5.00. However take your cord out of back of TV, and go somehwere in house where you may have stored cords in the past, like I do for it comes in handy to see the shape of end that plugs into TV is the exact same as all PC connections for power.

So it may not be these Y coonection X stuff TV repair men talk of, and you may not have to go as far as taking your TV apart like I see some do. My example of don't replace your timing belt when it's a spark plug for your car, and don't be having repair men getting paid just to show up at your house. Try this it worked for me and my TV is 3 years old.

I also suggest to save your plasma TV, I was given a pointer to chnage your color temperature to cold, when you have option of like hot warm cold on your menu. I was gievn a pointer the cool color temperature will make your plasma last longer then to have in in warmer modes and it doesn't seem to really affect my 1080 picture. I did that after I plugged in my PC cord to TV. I am all set now. So it may not happen for you first attempt, so cycle and try. When I did this with original cord it was stubborn and after unplugging and putting back on it worked, then after I shut down again it wouldn't at all no matter how many times. A darn PC connection and different power supply cord did it as others in here look for an actual Phillips cord replacement whcih seems to be according to other bloggers non existant which I really don't know the truth to that. Doug said this was something Phillips Customer servioce didn't give pointers on, and the only person that fixed it was you or me. However advice is your tv gopes blnk sometimes and back on and your under warranty, call them ASAP and don't let them give you the run around to staul you deliberatly to get you passed the warranty period, from what I read is the Phillips compnay is like look, you paid us much money for your TV, and now you have the same problem everyone else does, and your warranty has expired, so in other words their attitude is take a jump in the lake pal.

It seems that the plug to PC that is now my TV power cord was more snug to rear to connect then original cord. According to Doug, the cords were shiiped from China ( go figure ) anmd their have been power issues even with Sony and much more for faulty power cords in which they are manufactured there. The PC cord was made in China, however it was a change that my TV seemed to enjoy, and I suggest you try this and give it a few attemps before you go spending 100's if not more then 1,000.00 to fix, when it usually means your better off just getting a new TV. Look the economy is bad and their are TV repair men, but that's how they make a living. For them to not get paid a decent fee to see your tv and fix it is not the way they can make their money by telling you to plug a PC cord into your TV and they get paid squat. So try that and good luck, my TV is working great. It's just some power cords over time just s#%t the bed.

Thanks Doug Mohr!

I need the remote code for a Techwood twd fv2a. The remote died and I have a universal remote, but no codes to programme it with. I've looked everywhere online but can't find anything.


In this case, you need to post both the brand names and model numbers involved in your request.Simplest would be to buy a new replacement remote and you can start here:
Remotes.com
Also, there is no such thing as a 'universal' remote; they are programmed with known codes available at the time of manufacture and sets that come on the market later than the remote will not be covered at all or only incompletely.
Some (expensive) remotes allow downloading of later code sets for newer models.

Philips LX3600D Home theatre always returns to standby mode


There is a 1ohm resistor on the 4x4 pcb as soon as you take off the cover. ( I forget the ID # ) It supplys the -15volts to the control bd. The resistor will not looked burned. It was under rated. An ohm meter will find it ( open ). Rreplace it with a 1/3 watt. I believe the orig. was a 1/4 watt.

5.1 Home Theatre - PC


Its due to 2.1 channel sound input from your PC. Your Laptop supports only 2.1 channel sound so all the 5 speakers cant be played at a time! You need 5.1 channel input to work all 5 speakers
