Question about Sony FD Trinitron WEGA KV-36HS500 36" TV

1 Answer

Tuner doesn't work

All of a sudden, in the middle of a show, the TV channel changed from 3 to 6. At first, I couldn't change it to any other channel. It just scrolled 6, 66, and 666. Now I can get the tuner to rest on a station, but it changes back in a few seconds, unless I lock it in, which is the poor solution I am implementing now, with channel 3 (for the cable). Anyone have an idea what's going on? Thanks.

Either the tuner or the video IF stage circuit of your TV is faulty. Tuner has no repair, can be replaced as a unit. If the fault is with video IF stage, it can be repaired. But, both the work is skilled one. You must have through knowledge in electronics, and work experience to do this work.

How do we scan/program in local tv channels. We bought an external antenna, but get no picture. Typically, there is a protocol for scanning channels into the set. Model is Sansui TVS2746B, and the set was...


Okay, does this tv have a built in DIGITAL tuner? Most tv's only have an analog tuner. You can tell the difference while you are changing the channels. If the channel indicates 2.1 or 2.2 and so forth, it is on a digital channel mode. If you change the channel and it indicated 2, 3, 4, etc. it is analog. If it has digital capability change the input until you see 2.1, 3.4 etc. If you cycle through all the inputs on the tv like, input 1 (TV) input 2(DVD) input 3(HDMI) and so forth and you never see the digital channel you most likely do not have a digital tuner. You will need to purchase a digital converter which will convert it to analog and you can watch it by placing you tv on analog channel 3 just like the old vcr's. Hope this helps and please don't forget to rate this solution.

Tuner will not pick up cable box on channel 3, front and rear AV


In order for the TV to work with the cable box by using a piece of coax and tuning the TV to channel 3, you must make sure the TV is in "Cable" mode on the tuner and not "AIR or Antenna" the frequency maps are different between these types of service and channel 3 cable will not be the same as channel 3 on Air or UHF/VHF.

Often there is an auto program feature on TV's that will "scan" for all available channels, and this should select the proper input type.

Hope this helps!

Tuner doesn't work


I think this may be more of a fault with the uPC area on the main board than a tuner failure. It is possible to have both at fault, but this would be rare.

The numbers you see on the screen is from a pre-scaler circuit that drives a font generator in one of the IC's near to the uPC area. If you see the numbers changing this more from the uPC than from the tuner iteslf.

Cable setuo for model 27r410t


Get an antenna hooked up, even rabbit ears should pull in a few analog channels. Set top boxes will only output Ch 3 (switcheable to ch 4 on the back if needed) and cable may be dead or only give you scrambled CATV channels. You need to set your tuner to "antenna", not CATV, IRC,HRC, or ATSC (if you have a digital tuner) and do the setup again. You could have a bad tuner at worst, and all is not lost, just hook up a VCR via RCA cables and use the VCR tuner to change channels. Keep TV on Ch3.

That works great except I can get the tuner to program any channels above channel47. Is this a limitation of this older model TV yes there is limitation in old tv. is there some setting I can change in order to get more channels using the tv tuner? in INDIA what we do is put a remote control ckt which gives us about 250 channels. of course we replace tuner also called hyper tuner along with remote ckt or replace whole kit which are cheaply available.& serves the purpose. hope this will help
