Question about Sony KV-27V42 27" TV

2 Answers

Unavailable Part I have a Sony Trinitron model KV-27V42. It's about 7 years old, and it shut off while I was watching it. When I try to turn it on, I can hear it click like it always does, and then the screen remains blank. There is a red standby/timer button that flashes a couple times every 30 seconds or so. A repairman diagnosed that I need a Power Supply Board - Complete Part # A1298901A is no longer available. Is there a compatible part out there that can be used instead of the one identifed by the repairman/technician?

Re: Unavailable Part

I 've been an electronic tech for more than 20 yrs, and a tv tech for many yrs as well, the problem you describe; the power supply board needs to be repaired as well as the main board, on the main board usually the Horizontal output, however, parts should readily be available for both, I've worked on and repaired many of these model tv's. hope this helps.

I have a Sony FD Trinitron 27' Model # KV-27FV310. It is approx 8 years old. After turning it on and watching a full screen for a few minutes; all of a sudden, a line came across half the screen;

top half missing is in vertical circuit of set---if it is a 27 inch and this old consider retiring it and replacing----other option is consider having a shop repair it--a rough guess would be as high as 150 dollars parts and labor is possible for your problems.

Tv shut itself off while I was watching.

The power supply will need to be replaced. You can get them for $30 plus dollars and solder them in.

The 'pop' may have been an arc of electricity from the flyback coil. The flyback is the device that produces very HIGH VOLTAGES --that can kill so be careful--. It may have just goten old and the material around the flyback broke down and allowed the electricity to arc to a near by source to ground. it happens when CRT sets get old. Typically I expect 7-10 years of a consumer grade CRT. Other then that any fix for it would have to be performed by a trained technician because voltages can linger in the 'caps' and even the 'tube' itself for years, I once got 'bit' by a set that was left un-plugged for 5 years.

If hte set is a Sony, the standby light should be blinking a code. Report that code here and we should be able to guide you. That code will indicate the problem circuit within the set that has the fault.
