Under the main menu, go to the Parent tab and enter the Master Password: 4357. This will completely clear the present password. You can enter a new one afterward.

SOURCE: Sony Wega TV --24F... does it need a converter?

There are several ways to answer this question. First, let me begin with the Sony WEGAs are excellent TV's and have some great features and a very nice picture. However, the TV is an NTSC TV with no built in HD tuner.

Ultimately, yes, you will need a converter box to receive broadcast TV. However, this depends on where you live. There are a few markets left that have not switched entirely to HDTV broadcast yet. However, the switch in all markets is happening now and soon, NTSC broadcast will be all but gone (perhaps a few private rogue stations will continue w/ NTSC).
Now, to clarify, the $50 converter box is only needed if you intend to hook the TV up to an aerial antenna. If you have cable, your cable company will provide you with a cable box that will be compatible with this TV. Also, if you subscribe to satellite (DTV or Direct), these companies offer a variety of receivers that will output to a variety of TV's.
The $50 converter box is only designed to receive broadcast HDTV signals and convert the A/V into analogue (NTSC). The converter box will not improve your reception nor is it cable ready. In other words, if you have cable and are looking for a way around paying rental on a cable box, this will not work. Again, the $50 converter box will only work with an aerial broadcast signal (rabbit ears / rooftop antenna).

One last thing, the TV does have component video inputs. This does not mean that the TV is HD ready. However, it does allow for better picture clarity from video sources such as DVD, cable boxes (with component out), and / or DTV boxes (with component out).

Enjoy your new inheritance!

I have over 10 years experience in electronic tech support.

I know this isn't what you want to hear, but the problem you've described can't be fixed with
troubleshooting. Your TV will have to be repaired. There is a part that has developed a defect and needs to be replaced. If you're still in warranty, the TV will be repaired at no charge to you. The warranty would likely be at least one year from the date of purchase from the manufacturer. If you purchased an extended service plan they will repair the TV at no charge as well.

If the TV is no longer in warranty, it will likely cost a minimum of $150 parts and labor. This is assuming that you only need one
circuit board or small part. If the problem is more than one of the circuit boards, the price of repair could go much higher.

I hope I've provided you useful assistance and that this information allows you to make an informed decision as to how to proceed from here. Please be sure to vote on my response. I hope I've earned a good rating from you today.

Please let me know if I can be of further assistance.

Sony kv-27v40 standby/timer blinks 5 times


Five blinks - AKB circuit (automatic kine bias), the timer/standby indicator blinks for about 30 seconds then goes to the self-diagnosis function. Something is wrong with the video. Check video out, Q705, 732, 761 and other components on the C board, also check Q218, 219, 220 on the A board. In addition, unit could be in IK blanking, try turning up screen slightly.

Will only turn on for about 3 second with no picture and then turns off. Standby light blinks 6 times


For the KV30HS420, 6 blinks, pause, 6 blinks, etc. means "LOW +B OCP/OVP (overcurrent/overvoltage)" and the probable cause locations listed are as follows:

1. +5 line is overloaded (A, B, M boards)
2. +5 line is shorted (A, B, M boards)
3. IC504 is faulty (A board)


hope this helps John

TV went off, standby timer light flashing


Try unpluging from the wall and theplug back in and try turning back on to reset. Sometimes holding the power button in while pluging back in will reset it, every brand is different for the hard reset.

Will not come on and front lights flashing red +


If your set is the KV-24FS120, then the standby light should blink with a repeated pattern. Count the blinks and post that number here. It is a diagnostic code that will indicate the defective circuit. Having that information will allow us to suggest repair options.

Thanks,
Dan

Power on no picture no sound


the 2 bilnks is a fault code for a (b+ overcurrent), you could have a bad horizontal output check q506 or q505, varies by modle. I have also run into a bad color amp ic1751. use a multimeter to test the h. o/p transistor, as for the ic, easier to replace than test.
