TV Repair Questions? Ask a TV Technician for Answers ASAP
Thanks for the question. I'm Dan.
This is not an easy repair.
You've lost the HOT (horizontal output transistor) for sure.
So that will need to be replaced.
But WHY did it die...?
That's a can of worms. Usually it's a few bad caps. But that normally leads to some open resistors and diodes, too.
We're not really talking big money here, but the time and knowledge will be extensive.
I'll await your thoughts.
Hi Dan, thanks... For quite awhile before that, the set had jittery video when cold, usually improved after warming up a half-hour or so. Would that be related to the failure? My tech experience involves mainly musical instrument amps (tube and discrete ss), so I don't know if this is something I should tackle...
Yes, those symptoms make sense. Considering the age of the TV, you almost certainly have some cold / broken solder joints, too.
Honestly, we're probably looking at a pretty significant overhaul based on the symptoms.
The thing is...
If you've never worked inside a TV before, I really wouldn't want to start with this one.
I would start with a more modern LCD / LED or even plasma to work on. They're much safer, and a little more black and white.
I see... would you be able to guess any kind of ballpark figure for what an in-home repair might cost? In other words, should I just replace it with a flatscreen and call it a day?
Of course. For parts, we're looking at $25-$50.
"more black and white"...great pun!
The HOT is $15, then some little caps / diodes / resistors.
Haha you caught that!
The labor is gonna get you, though... you're probably looking at 1.5 hours maybe 2... so add $100 or so, to the part cost.
That would be in-shop, though. In-home would vary quite a bit by location, but would be more.
So, likely $150-$200 then? That's not ridiculous...
Right...it about killed my roomie and me getting it in the house, so that'd be necessary
Nah, it's not bad. But you can get a brand new 37" LCD for about double that.
So you're right on the tipping point. Usually if it's going to cost more than 50% of a new one, the rule of thumb is that you replace it. Some people say 75% but I think they're being sentimental.
I'd agree on that. Maybe if I can get a free estimate (do shops do that anymore?) it'd make my mind up for me
In my area, a TV that size would be $35 for diagnostics.
If the estimate is outrageous, you'd just have to eat that fee then replace the TV.
But at least you would know for sure.
Right...well, I guess I'll inquire local shops re. their dx policy and go from there. I appreciate your candid opinion on this!
My pleasure. If you need anything else, don't hesitate.
If you want, I can leave this question open and you can get back to me with what the guy says.
I will do that, thanks.
To close this particular session, kindly leave a service rating (smile face, then submit).
Will do, have a great day Dan, TTYL!
OK, take care!
