My Korg DT-10 Tuner is broken. I think it is the power supply. Do you think it is cheaper to repair it or should I just get a new one?


if your pretty sure its a crack in the circuit board from dropping or rough treatment then yes it can be repaired in less than an hour-contact a guitar repair center to see who does there electronics repairs they might take that on if asked , but if it just started to do this with out a known cause its most likely a component failure and that will take some time and knowledge to find cause and repair , on this unit that might not be feasible to do

Sound does not work.


either is sound IC has blown, or the sound section of the tuner needs a repair. I have repaired many tuners for sound. Some technicians never repair a tuner hence it would need a replacement if it can be physically removed. If a tuner is printed on the main board the whole board may need to be replaced.

My sony 52wx4 tuner will not work. cd and aux does, but not tuner. Lights up but no sound


some of the sony tuners did have inherent problems, if your unit is a cdx-gt260 then most of these had tuner problems. best to change the entire tuner "circuit can/module" in the unit. or check out your sony service center for repair advice/cost. cheers.

I have INSIGNIA TV 42"


Hi shaan99,
There's some shop that expertised in tv tuner repair. But this shop is very hard to find and sometimes the cost will be the same like the original price of it. You can replaced the tuner by yourself, all you have to do is prepare soldering iron, disoldering pump and soldering lead and the tuner replacement http://cgi.ebay.com/ENV56S02D8F-TV-TUNER-/230591288708?pt=LH_DefaultDomain_0&hash=item35b04fd584#ht_500wt_949.
Hope I helped you.
Have a nice day!
Thanks for using Fixya.

My son tripped over the cable cord and the cable/antenna input came off. Is it repairable and is it costly to get it fixed


It depends if the connector broke the tuner it is attached to. Most times the chassis of the set would need to go into the shop. I would generally charge $80.00-$120.00 if the tuner was still good - a new tuner would cost $60-$100 more if bad
The better solution is to use the video audio inputs (if on satellite or cable box) or use the video inputs by changing channels through the VCR (if on cable or antenna and a VCR is available)

Sony Trinitron - Model KV35S66


The tuners in many Sony sets often develop bad solder connections that can cause this kind of tuning trouble. The tuner can be replaced to fix the problem, and it's also often possible to repair it. To repair the tuner, it needs to be removed from the board in the set, the cover removed, and all the connections from the tuner circuit board to the metal shield can need to be resoldered. The metal can is used as the ground connection for many places on the tuner, and the connections develop cracks and become intermittent or fail completely. When you use the video input, you bypass the tuner so you have the nice clear picture.

This repair should be handled by a technician who's experienced with soldering on small circuit boards. Improperly done, this repair can do more damage to the small, closely-spaced circuit board traces. Many technicians would rather simply replace the tuner than do the repair. Depending on the price of the part and how labor is charged, it may cost the same either way.

Can a flat screen TV with ASC tuner pushed inside be repaired?


sue_shellenb,

I am an installer for a nationwide big blue store. The inputs on the back of tv's are fairly fragile. In my opinion, if the tuner to tv interface is damaged, ("In the process the ASC tuner, or internal tuner, was pushed back into the TV and the technician said it couldn't be repaired.") it probably is not repairable. Or at least, not economically repairable. Cheaper to replace the whole tv.

On the up side, $850 is pretty cheap for a 47 inch flat screen.

Tuner


whats wrong with the old tuner? did the connector break? depending on the damage the connector can be replaced to replace the tuner right out i would call a medium difficult level. it invovles removeing the signal board the board with the tuner on it simply unsoldering and replacings care should be taken not damage surface mounted components. at the shop it is possible we repair these tuner which involves opening the can tuner and soldering a new connector to the can of the tuner.
