Help - TV Repair North London
Discussion
Well, I never thought it would be so difficult, but after looking around for a week I still haven't found anyone who is able to come to my flat for half an hour and fix the dodgy connection on my TV.
Therefore, thought I would post here on the offchance that you guys might be able to recommend someone in the are to me. I'm in N8.

I'm in N8, my company is based in Enfield so can help you, depending on the make.....
What is it, and what's wrong ?
Its a big Toshiba (36Z something) and basically, the TV switches on but there is generally no picture. It then stays on for around 3 minutes before switching itself off.
Sometimes it will come on and the picture will appear after a couple of minutes, or sound alone can be heard, and then it switches off again.
Help much appreciated, especially if you do home calls and reckon you can fix it.

Eek. My engineer thinks probably the tube,££££. Having said this, most faults will cause it to shut down, but previous experience suggests the tube...
We can come out to take a look although I suspect it would have to come in for repair.
Cost to have a look is 29.00
Rough cost to get it fixed if it is the tube? Can I email you?
It powers down after a few minutes and he thinks it is the tube? "It's the tube" used to be code for "it sounds a bit of a nightmare fault, I have too much work as it is and don't want to touch this set with a bargepole" (my dad used to mend TV/VCR/Audio equipment). New tubes are usually nearly the same price as a replacement TV and thus the excuse is usually invoked to make the customer buy a new one.
Tube faults tend to be *very* noticeable. To me it sounds like a bad electrolytic capacitor in the switched mode power supply and I would go for a second opinion.

Yep. One thing it isn't, is the tube...
A dodgy electro is a possibility but the fault is usually more consistent. The fact that you sometimes get a picture, and sometimes get sound, and sometimes get nothing is more suggestive of a bad connection. (You can get a bad connection occurring internally to an electrolytic capacitor but it's not one of their more common failure modes.)
Bad soldered connections are usually pretty easy to spot. A bright light and a magnifying glass can help. You can see a dark ring around the cone of solder where the component is soldered into the circuit board.
Bad electrolytics can sometimes be spotted visually - sometimes the flat end of the can is bulging and/or the plastic sleeve has shrunk. However, they also fail without visible sign in which case more complicated methods have to be used.
