LCD TV problem

[Yaloryalor]

I have 1 Sharp LCD TV in my bed room. Only recently whenever I watch Channel U for about 15~20 minutes; the signal will be interfered and become blue screen (only Channel U has this problem). However, I verify with another TV, there is good signal on Channel U.

 

If I switch off and on again in 20 min time, the signal is back again.

 

Is it my TV got problem with Channel U frequency? Cos I program another channel to Channel U freq also got this problem.

 

Cannot be signal reception problem rite as other channles no prob at all.

 

Any bro/ expert can advice?

Sounds very similar to my situation.. my 5 years Sharp LCD in my bedroom would give blue screen for channel 8 at times. I tried switching channels when the problem comes and other channels are okay.

 

Usually I adjust the tv signal cable and it gets better sometimes. Almost gave up and thought of getting a new tv. However, the issue seems improved after I get a new SCV cable. Also made sure the cable is not cramped. Not sure why only one channel is affected.

 

So far so good, keep my fingers crossed.

 

You can try testing the tv with another SCV point and also another SCV cable. Change a thing at a time to troubleshoot slowly. Let me know if you find something.

My problem is my TV is wall mounted (boxed out) and had a feature wall. The cables are hidden. Hence now wanna change LCD TV also got size limitation..

 

My Sharp LCD TV also bought 5 years plus liao. 19" cost $2.2K last time.

Very troublesome then.. I am already quite lazy even though mine is just mounted on the wall with a mounting bracket.

U might need a signal booster... Can get one from SLT....

Is your cable point installed by SH or 3rd party contractors? If it's by 3rd party then that could be the problem. They might have used lousy cables and splitters resulting in high losses. Just a guess.

I suppose the problem did not exist and only comes recently? It happened to me. My tv was working fine for years, then got the tuner replaced because we can no longer receive tv signal. Then the occasional no signal problem for a particular channel comes.

Thanks Guys!

 

Like Clemenzo mentioned; mine was also working fine for many years but only recently got issue on 1 channel (channel U) only.

 

If need signal booster or my contractor use lousy cable then the problem should surface out few years ago..

 

Really confuse..

Bro, jus to update..

 

Mine confirmed case is the TV issue. I have use another TV for the same cable, no prob. At the same time, I moved the LCD TV to another room using another cable, the Channel still cannot watch.

 

I have bought a new TV.

 

Case closed. haha..

Good for you! Maybe the tuner has a problem with that channel. Mine is still ok, no excuse to change..

Sorry to hijack this thread.

 

Wondering if anyone here knows what's wrong with my lcd tv. It's a philips cineos model. Intermittently the screen goes off... Not often but when it happens, i need to switch off and on a couple of times before it's ok again.

 

It's coming to 4 years already and warranty is over. Actually this problem happen even during warranty period but the technician came and fix the problem... Now it's back again..

 

Anyone knows what's wrong?

[Clemenzo]

Any idea if any part was replaced then?

i dun think there was any parts replaced then... i remebered the technician did some soldering and he said dunno what part was loose, that's why on/off intermittent... after the tv was serviced it was ok... until recently when warranty over, the same old problem came back.

 

just unlucky..

My CRT same case as you. Maybe the speaker really did get softer over the years or our hearing becoming worse or both.
