Question about Projection Televisions

2 Answers

I have got a polaroid flat screen tv. model no. polaroid TLU 03711C. I have had this tv for less than a year, and it is still under warranty just. however over the last 4 months or so, when i first turn the tele on it makes a high pitch buzzing sound for the first 10 minutes its on. if u turn the volume down this will not go away, but if u mute it, the sound dissapears. i was just wondering if this is a problem with the tv or something else. it has become rele annoying and has bin going on for about 4 months. it happens every time u turn the tv on without fail. thanks

I had the same problem - It was due to these two tiny devices called "capacitors" which had blown. I replaced them (it only cost me £1!) and was really easy.
I wrote a guide on how to change the capacitors, there are pictures an d the guide is easy to follow. You can print, download or view the guide here - http://www.scribd.com/doc/13515584/Polaroid-TLU03711C-Replace-Capacitors-Guide

Air flow vent is blocked, tv keeps shutting down, mitsubishi ws-55615, how to fix ?


Mitsubishi's product line includes a wide array of LCD, Flat Panel, and DLP televisions to suit your home entertainment needs. The electronics division has the distinction of inventing the first rear-projection television and selling the very first HDTV in America. Their 400,000 square foot manufacturing facility, located in Irvine, CA, boasts the ability to produce more than 1,000 projection TV's in one day. The company's oft-stated goal of unmatched excellence is driven by their mantra: "Technically, anything is possible." In June, 2008, Mitsubishi introduced a new premium flat panel TV with an integrated 16-speaker sound projector.
Warranty Information
There is in-home service on all big screen models, which have warranties of 30 days for screens and one year for parts and labor. The LCD televisions have a one year warranty on parts and one year on labor with carry-in service. For plasma sets, in-home service is available on all models. There is a one year warranty on parts and one year on labor. The faulty thermal sensor, mentioned in the commmon repairs section, is now covered by an extended 2 year warranty, as is the problem related to the optical engine.
Common Repairs
For the following models: WD-52631, WD-57731, WD-65731, WD-Y57, WD-Y65, WD-57732, WD-65732, WD-57831, WD-65831, the most common repair problem stems from television shutting off almost immediately after it has been turned on accompanied by the message, "TV will shut down in a few seconds. Please check if the air flow is blocked." According to the Mitsubishi website, this issue is caused by a loose connection as a result of a faulty thermal sensor. For models: WD-73727, WD-73827, WD-73927, WD-73732, WD-7383, the most encountered repair problem has been in relation to the optical engine. Another common situation consumers have encountered is failure of the TV to turn on along with unceasing flashing of the green power light. The solution for this problem, caused by the DM board, will vary by repairman. Consumers have also encountered issues with moving vertical or horizontal lines appearing on the screen which can either be due to problems with the capacitor, light engine, or formatter board.

Transporting plasma home something hit the screen now the tv is not working. It is a sony 106cm plasma. Can this be fixed and be cost effective or better to buy a new one


If you damaged the plasma display, the job willbe over $1000, depending on the model.

If you damaged a different part, the repair wont be less than $200 in the best case.

I suggest to call the manufacturer and ask the cost for a warranty extension.

A warranty extension costs usually less than one single repair ($200 or less for an average plasma TV), and will cover all repairs for one year.

If you want to call the manufacturer you can use the phone number listed on the owner manual.

New (12/2007) 1080p Samsung 46" LCD TV. Flickering white horizontal lines on entire left screen. Double picture. What's up?


At this point there is not much you can do.
If this LCD is less then a year old, I would suggest to contact the manufacturers to get it fix under their warranty.
Good Luck.

FLM-373B Polaroid tv will not come on. The blue light comes on and when you turn it off the red light shows up. The screen of the tv is black and no sound. Can you solve this problem without calling a...


Same problem here. Polaroid Tech Support says that it is the control box.

It is a little over a year old so it is out of warranty with Polaroid.

Except, I bought the two year plan when I bought it at Walmart. So I called them and they are sending me a box and a shipping label to mail it back for repair. I tried to tell tham that is a little big to mail but they insist. This should be fun.
