Nor would I!
Only an expert should remove the back of your CRT TV.

Thanks for the comments, have looked at HD they are pretty good. BUT you really need sky or some hd source for that stunning picture. Standard def, which we mainly view looks terrible. would feel a bit sick parting with £700 for a picture quality worse then I have! Will have a look at the solder connections, spoke to an engineer before who thought it may be the solders on the board at the back of tube, but they all looked ok. If it proves unsuccessful, was looking at a samsung le40c750 might have to get the wallet out:(

SD pictures on a half reasonable LCD TV will look pretty good. Unless you get up close or have a particularly large screen, you'll barely notice the difference between SD and HD. You might be able to see the difference on a 40" TV, but you'll have to switch between SD and HD to appreciate it. It's quite a hotly discussed topic on here though, so doubtless others will come along and say otherwise!
HD is coming to Freeview anyway, so no need to think you'll only see it if you get Sky.

Been here since April 2010.

Just got a Freeview HD Sony.

I agree, if you are viewing standard definition content then it does look a bit carp - but you do get used to it and now i don't really notice it at all

My blu ray player looks absolutely stunning on my 1080p 42" LCD, as does my Xbox 360

Also i agree about Freeview HD - Free HD content to your HD TV, can't be bad

The fault on your TV sounds like dry joints and probably also bad electrolytic caps. Very straightforward to repair, but unless you know what you are doing don't attempt it yourself. If you live near Bracknell I could repair it for you at reasonable cost in my TV business.

CRT sets are worth repairing, you will get nothing like the same life out of a new LCD set - and repair costs of many of those are horrendous if they do go wrong.

I was quoted £180 & fitting the xmas before last for a new power board on my 42" Sammy flat screen, two 24p caps from Maplins and it's still working to this day.

Of note (1) was the fact that the caps used at manufacturing level were ' right on the edge ' of capability and were only ever going to fail, and (2) anyone can stick a powerboard in for a couple of hundred quid but it only takes an extra twenty minutes to check / de-solder / and re-solder a couple of caps.

I'll tell you a decade old story about my 25" SONY CRT and the grand-kids little ink stamp, if you ask.

The fault is dry joints on the frame chip and there probably will be some tired caps as well.
Repairable for sure and if you were my customer it would be £30 total.

Richie, the Samsungs are easily repaired but you should use better, higher rated and physically larger caps, sometimes the set will be dead still after the power supply repair, this means the eeprom has been corrupted and needs to be replaced. This usually happens if the set has been used in the faulty condition for a while....
So, if your Samsung is playing up get it looked at asap. I charge £50 total or £60 total if the eeprom needs changing.
There are many honest TV engineers out there still if you look.
I also know of some who charge £180 but fit a repaired board and use the faulty one in the next set!

As you all say, LCD/Plasma sets are OK if you have a high definition source.
They can be expensive to repair, especially plasma sets.

Ta mate, the set still works brill two years later, but the EEprom was / is corrupted. Irrelevant in my case as I only ever use HDMi, and it defaults to HDMI regardless of what's plugged in - and that's weird, the default is always SCART as far as I know..but I'm not a TV spark, or an EEprom writer !

I changed the cheepo 10v 2200µF for for much bigger [ anything bigger than 16 had legs thicker than Norah Batty's :rotfl: nylons and wouldn't go through the board ] 16v's, I had to leave the legs long and bend~em out of the way, they were the size of dustbins.

On the EEprom, I was going to find one and replace it, but as I say its HDMi single use only so no point. Like tens of thousands of other Sammys it went at 13 months

Look I'm sure there are many honest repairers out there but in my massive town as far as I'm aware we have one, only one.

With your permission I'll re-quote your tip "" if your Samsung TV is playing up get it looked at asap "" for others who might read this thread :T

Trevor sell me a EEprom, and I'll stick it in, if you PM me I'll give you the spec etc.

Electrolytics are often a problem spenderdave, but, I don't think for one minute that they're a problem with this fault, or banging the set would have no effect at all.
Short circuit / leaky / low capacitance,.... banging won't help.
