20 Most Recent Sony Bravia KDL-32V4000 32 in. LCD TV Questions & Answers


Those blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices.

If blinks continue without any pause, the main board is faulty.

There are a few things to ponder here...probably the high voltage inverter power board is shutting down due to excess power drawn from CCFL(cold cathode fluorescent lamps) . This will happen eventually as a carbon track starts to grow down the tube drawing more current . There has to be a lot of hours for this to happen .
Sony was not free from the bad capacitor affliction...an ESR tester is not an expensive investment unless you only use it once but it can find bad caps that are not showing signs of ***** ie:leakage ,swelling.
failing ballast transformers would be replaced by new inverter board . This would be a last resort without schematic and instrumentation to get hard data to find culprit .
The CCFL tubes can be replaced and may be worth the time and effort with sweat equity . At approx 40.00 usd for 10 you would have to decide for a mere 32 inch LCD TV .
I would spend the money to get an LED TV and get longer service life and possibly better features ie: smart TV

Set-up (Programming) procedure is too much to type in here, and is not practical and it will differ brand-to-brand remote controls. If you wish to get more; check the sites linked here.

Programming Notes
• If your device does not respond to the remote after trying all codes listed or your brand is not listed in the code list, use the Auto Code Search method to program your remote.
• Sometimes the first code that "works" with your device may operate only a few functions of your device. There may be another code in the code list that performs more functions. Try other codes from the code list for more functionality.
This is a trial and error procedure; and quiet time consuming. You might have to check different codes said for your device.

Fault to the main power supply regulator section. Either it will be a separate board, or the part of main board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here.

It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.

the web began to take over some of the functions of teletext from the late 1990s, and many broadcasters have ceased broadcast of teletext-CNN in 2006 and the BBC in 2012. The decline of teletext has been hastened by the introduction of digital television, though an aspect of teletext continues in closed caption .
