The small signal board is usually what causes that problem.

First - connect DVD player preferably to the same input (unless you are using RF connector) and make sure that same issue does happens while you are watching movies. If it does - main board in your TV have to be replaced. If it does not - it still cable signal problem.

TV turns off when you change the channel


sounds like a power fault, prob just weak capacitors if you can change them it would not cost a lot to replace them, when you change channel it draws more power and if its at its limit it will turn off as the capacitors cannot take it. few £'s or $s to get the replacement capacitors, you will probably see the blown capacitors on the power board as the will not have flat tops they will be rounded, change them same for same i.e 16v 330 for same 105c type would be best. it will say this on the capacitor.

TV stuck on blue video screen


This usually happens when you are on a source that doesn't have a signal such as a channel with no signal or an AV input that is not connected.

You should look for a button that has TV/VCR or TV/VIDEO on it. I've guessing that you've already tried to change the channel but if not try that.

Last ditch effort in that case may be to unplug the TV for a few secouds. Warning- this may wipe out any settings you have entered such as the channel programming (which channels to skip while surfing) but along with that goes the blue screen.

No colour when digital set top box attached


Ensure the set top box is set to the correct video out. Probably RGB if scart lead or CVBS if coax lead.

This may sound stupid and not help anything but I would change the batteries in the remote first; that's the simplest possibility.

What the set is doing is selecting a function, the first is 'Auto tune' during which the set is looking for usable channels on the 'off air' (antenna) input. I suspect you have cable or satellite meaning that there will not be any signal at the antenna input and the set just looks at each standard channel frequency and then gives up.

The language thing; this is curious but also a sign that it has switched to the menu mode where you also need to be if you want to do a channel search on purpose.

If the remote is not at fault, then it is an internal problem you will not be able to repair on your own.
The circuitry that interprets the received infrared signal from your remote has started producing noise or the output from that after a decoder, has gone noisy and is just choosing functions on its own.

The blue screen is what most sets use as a default when no signal is found at any input.

Unfortunately. Emerson, RCA, Zenith and a few others are US names we once trusted but now have been acquired by Asian manufacturers who are building junk with labor pulled from the fields to assemble high tech gear.
