Question about Samsung HLN437W 43" Rear Projection HDTV
Ok, if this were me I would suggest a thermal issue, some component(s)? are heating up, and the system is then hanging up? This can be in one of many places, however the most likely candidate is the switched mode power supply, either this is, or it is being affected or is shutting down the set due to a potential fault, that may be what's called a catastrophic fault, insomuch, as it may result in component failure that may cause a fire an explosion or both. What you describe indeed fits in, the non-starting, the waiting and it then starting, having to plug, unplug, the freezing, this all is indicative of this type of fault. But to be perfectly frank, without examining the set,it is almost impossible to tell exactly.
Seriously these days irrespective of what "others" may say, & I have been servicing for over 30 years, the DIY servicing of modern day TV sets, and for that matter this applies to most electronics, these days. Well it isn't really economic nor practical. to repair, and I see time and time again in these posts and forums, and in my shop, where people embark upon the repair, with hearts & minds full of good intentions and little else, and then often end up with a large bill, a bag of "Boards" and still, a non-working set, and then, they still must either pay a technician, to try and repair it, or purchase another one...
So usually I recommend to all, that the very best and cheapest way to get a working TV set again. Is to take it to a place that deals with the, your, product. Now, always ask first, for a "Quote' as to the cost and nature of the fault/repairs, and then and only then make a decision as to what to do, repair or replace?
