Top 20 Memorex MLT3221 32 in. LCD TV Questions & Answers

Check whether the audio is half muted by accidental press at remote control button. Enter its sound menu, and check it. If muted, as you know there will be no audio output. If not muted, check the speaker/s. If found OK; check and replace the damaged component/s at its audio output section circuit board. If needy, replace this board as card basis.

Main digital board fault. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. http://electro-medical.blogspot.com/ http://electronicshelponline.blogspot.com/ In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.

If you mean a firmware update to the MLTD3222, there is no way for a user to update this TV with built-in DVD player. The manufacturer doesn't provide updates and has no way to access them from a DVD, USB flash drive or SD card. (The manual for the related MLTD2622 is available from Memorex support: http://support.memorex.com/app/answers/detail/a_id/939 . ) I wish that I had better news for you. Cindy Wells

Fault to the main power supply regulator section. Either it will be on a separate board, or on the part of its main board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. http://electronicshelponline.blogspot.com/ It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.

Check if you got a picture somewere in the dark screen. If you got anything moving but very dark, then you need a new invertor. If its totally dead you need a new card inside the tv. Its a job for a pro.

check the settings and see if he has any CC1 or CC's activated or any type of Closed Caption. The only time something like this happens is usually when you have it set for CC2 or something along those lines.

To know more about this, you have to get its repair manual. The manual will have disassemble procedure.To get more details, http://electronicshelponline.blogspot.com/

Check its speaker. If found OK, check and replace damaged component/s at it audio output section circuit. If you wish to get more details about the circuit diagram, check the site linked here. http://electronicshelponline.blogspot.com/ Pull up previous posts by its left sidebar, or type in the brand name and model number to of your set, to its search box, and press 'Enter' or view it in Mosaic / Timeslide option.

Check for bursted electrolytic capacitors at its main power supply regulator board. It will be best to replace the board as card basis, rather than making any 'surgery' to it. If you wish to get more details, check this link. http://electronicshelponline.blogspot.com/ Selecting the view option, either to Mosaic /Timeslide, can be selected by the drop-down list, at the top left of the display window, will make surf easy.

i was watching my tv and the scream went black

Just look at its back cover. All details will be there on a sticker.

Either there will be a button on the original remote or you look for it in the main menus for the set.

Please follow guidelines given in operation manuals of both.

Problem is not clear enough to offer a solution.

Look inside at the power supply board:This sounds like a very common issue.If set is hard to turn on (takes several tries)but will eventually turn on hereis what my guess would be.Every set has a standby power supplythat is running 7/24 if the set is plugged in and it supplies voltage to theremote circuit that turn on the main power supply for the tv and hence turn theset on.This is an area where companies cut corners by using lower rated voltage caps.By this I mean Standby usually provides under 10 volts to trigger the seton----what they do is use filter caps rated at say 10 volts max in a circuitwith 9 volts (example)=with the standby on all the time the filter caps(electrolytic caps) dry out and fail.The problem usually begins where you have to turn set on or or two times andgradually gets worse--takes longer and more tries to get it to come up.Once on it will stay on until turned off for a period of time.The caps will begin to work better (regain some of thecapacitance) as they get hot--hence one it is on it will seem ok.The beauty of this problem is most of themhappen when set is a year or two old (no warranty) and all you have to do islook at the top to locate bad ones.They are generally black or blue and round and vary in --they have twoconnections each--a + for positive and a - for negative--not unlike a batterywhich in a way they are. The + and - are marked on top and bottom of most boards.They are easy to replace and not expensive parts.The tops are silverand metal looking with creases on top and if bad they will be puffed up ontop---tops must be perfectly flat with no brown material leaking top or bottom.If this is your problem once you id them (make a drawing) you can begin.Here is the critical part---on each cap is also marked the value like 220uf 10vdc---220 micro farad at 10 volts maximum.If you find for example 6 puffed up and all are 10 vdc replace them with thesame value capacitance (like the 220 uf) but go up to at least in this case(from 10 volts) to a 16 or higher rated voltage cap.The only issue is when you go up in voltage rated value the cap is larger sosometimes there is an issue of physical space for the replacement on the boardto fit them in.The reason they cheapen these sets in this way is if 10 caps and you make25,000 sets there is a considerable savings in parts cost. They do not care as long as it lasts past the usual one year parts warranty.I have taken the time to be long winded because this really sounds like it maybe the problem you have.See attached photo of a typical cap and if you have questions or need advicelet me know.
