Top 20 Proton MM2701VT 27" TV - Page 3 Questions & Answers

Your TV is being overheated by the location it is placed. try moving it in an airy area and see if the problem still occurs. The turning on and off is a response to overheating sensors in the TV housing and if not rectified it could malfunction and may cause burnout, a possible risk of fire.

I would suspect the lamp first if it has never been replaced.

The problem is in either the pip module or the comb filter module and the repair shop should be able to bypass this module - I charge between 180-240 depending on where the home is.Get an estimate

push the menu button,try to look for an optioncall "Auto shut off" or "alarm".
google rca tv(model number,its on the back of your tv.)manual and read it.
dont worry your tv its not possessed.

I had a similar problem with my Phillips 42 in. LCD HD TV.

Here's the problem. The Power Supply Board. I opened my TV up(warranty was up of course) and found several bad capacitors. Phillips and several other companies were sold capacitors that although were highly rated failed within 5 years because of a lack of preservatives. All sorts of electronic equipment is now being effected due to these defective capacitors.
Solutions?
1. Take it in and have it fixed
2. Open it up, check the board for faulty capacitors(bulged or leaking) Buy a new Power supply board and install it.
3. Remove PSB, remove faulty capacitors and replace with compatible new ones.

Hope this helps

Loose grounds on the vertacal ic or the horizontal coil or a bad ground on a power resistor. Definitely a bad ground...Find someone to resolder these for you.

Hi, my suggestion would be to at least have it looked at and let the technician explain what happened and how much it will cost to fix .At that point you can make an informed decision as to have it repaired or have it replaced. If you can get it repaired then I am sure it would be less expensive that buying a new T.V.

Hello david_barber,

This sounds as if it could be a problem in the power supply section of this TV. Usually LCD TVs have problems with capacitors drying up and causing this type of issue. You can check this by opening the back of the TV and seeing if you can see any of the capacitors (can like components) that look bloated and or puffy (this is a sign that the capacitor was stressed for a period of time. Now as far as replacing the capacitors or even the board, I would suggest that this be done by a qualified TV Technician, due to the fact that there are procedures involved in the removal and replacement of parts that the technician would know of.

I hope this helps,

Thank you,

you need to go into the menu and turn off the software upgrade

just did it on mine and it works

Each Remote is Different... it will only work if the IR Codes Match your TV.. if they dont then you have no hope of getting it 2 work.. most likly just through it out... coz its prob just cheeper to buy a universal one from your local supermarket

check your ground

Its Probably overheated.

happened to me before then i took to fixers and they changed some part and now its fine or if u have a warrenty call the manafactuarer

The bang test is a good indication that there are poor solder connections inside the set. If you can solder and are comfortable working inside the set where potentially dangerous high voltages exist even when unplugged, you can fix this yourself. Look at the main board and resolder any joints that appear grainy or have rings. That should resolve the problem. If not, see if there are any changes in the symptoms and update this.

Hello valexandrur,

You are in the correct section, now your problem may be a shorted Integrated High Voltage Transformer (IHVT) also called a Fly-back Transformer and or a shorted Horizontal Output Transistor (HOT). I would first check the Transistor to see if it is shorted between the emitter and collector (to do this use a multimeter set to "Rx1") and the reading between the emitter and collector should be near infinite no reading, if the reading is 000 ohms then the transistor is shorted and should be replaced. Now for the hard part, you technically can not check for shorted transformer turns in the IHVT using a multimeter, you will have to use a device which will allow you to do what is called a ring test. If you do not have this piece of equipment (IHVT tester), I would replace the IHVT just as a matter of good measure, since the HOT had drawn a lot of current I would assume that the IHVT was damaged to since it is in the serial path between the collector of the transistor and the VCC supply.

I hope this helps,

Thank you,

Unless this set is really oddball, it probably has the same type power cord connector used on computers and so many other electronic appliances. If this is the case, you can use a standard computer power cord as a replacement. The computer cord is a three-wire plug with a ground pin and the TV probably only had a two-prong plug, but the cord will still fit. Your electric outlet should be the three-prong type (if it's not, get it replaced!) so the plug will fit.

If the connector in the set is really different, you can check online by doing a Google search for replacement parts for you TV.

You need a new color wheel. Go to www.samsung.com and do some searches. I had to have someone come out and replace mine.

have you changed contrast

are you sure the button is not stuck?

cant u just unplug from socket

sometimes wavey lines can come from your cable or satelite connections because the wrong size cable was used or there is just a bad connection in the cable somewhere..
