TV picture goes off after 20 minutes

Hi. Less than two years ago, my husband bought a 19 inch Technika tv from Tesco. About 6 months ago, the picture began to disappear after the tv had been on for about 20 minutes. The sound remained. If the tv is turned off, then on again, the picture comes back, maybe for 3 minutes, then goes off again. Can you help please?

a local search ought to work better for YOU.

Our TV picture works fine then blacks out with audio continuing to work ok.Now after some time picture works ok for about 20 seconds the blacks out with audio continuing on OK.While we bought this in 2008...


I think you chose a Westinghouse Lemon, go this site and read all of the negative reviews of this model;

http://reviews.cnet.com/flat-panel-tvs/westinghouse-sk-32h240s/4852-6482_7-32429419-2.html?tag=userReviews;page

Here's just one of the reviews;"best chunk of aluminum i ever had the fortune to buy"by stevecox25 on June 11, 2009-->
"Horrible customer service on a worse television" by westinghousecrap on March 20, 2009 Pros: Good picture once it is properly adjusted.
Cons: Low quality audio, had the TV for 10.5 months and the picture went out, sent the TV at MY expense to TX, and I've been waiting for 2 months, and customer service can only say that there is a "delay". And they don't send a new TV, it's a rebuild.
Summary: Please don't waste your money on this TV, spend a little more on a different brand and save yourself the headaches I've had. I'll never purchase a Westinghouse product again. Customer service has been no help, and their answers are vague at best. Learn from my nightmare, NCAA march madness on a old 19" TV because my Westinghouse quit working 2 months ago and they still haven't replaced it.

It's the 26 inch version but have problem with picture


Hi Paul,
It looks like your TV might have a main board failure if the screen stays white without video. Since your TV is less then a year, I would suggest to contact the manufacturers to get fix under warranty. Most electronics devices carry one year warranty.
Good Luck.

Blank white screen on my technika lcd tv...please help


if you have your receipt or bank statement and bought it from Tesco, then give the helpline a call on 0845456676 and they will issue a otm (over twelve month) form, this will allow you to hopefully claim back either partial exchange or partial refund
