Re: No Picture on Wharfedale tv
Appreciate the direct "Ask Me".
Your son's description of "...bang and smelt hot..." could indicate a number of possibilities:
power supply section;
horizontal section .
Since it has still sound, then the power supply is a least likely possibility. The "...bang and smelt hot..." is also significant. It tells us that we can visually check which component burst and burned by opening the rear of the unit for a look and see. Further diagnosis would of course would require a fair familiarity of electronic components/circuitry and safety procedures, use of a DVM and a soldering iron. It would be to your added advantage access to a service manual or at the very least a schematic diagram with voltage readings. Should you be uncomfortable performing a DIY (do-it-yourself), perhaps your best bet would then be to seek the services of a qualified professional.
Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.
Good luck and kind regards. Thank you for using FixYa.

It sounds that there is loose solder terminals to the terminals of Chroma IC. Re solder all the terminals by applying a little more solder to each terminal. In practice, it will be very difficult to detect these type of loose solder points. The only way, is to re solder all of them at one time.
DLP type sets regardless of brand all have some things in common--use a lamp, a Ballast, etc.
If sound you need to see if the lamp is coming on when set is turned on--usually in these type sets if no brightness one or more lights on the front of the set will be blinking---no model number is indicated with this question..
Wharfedale LCD3210HDAF this tv was working fine the night before ..
when i turned it on in the morning the screen came on then instantly
went blank .. although the sound is fine i am unable to get any on
screen including menu an volume information and of course can any one help ??
Sounds like something else in the power supply. The surge inrush current could have blown the bridge rectifier. (device which changes AC to a pulsating DC for the power supply). You may need to have the power supply serviced or replaced.
Our problem was that we could not get picture on the tv screen but it got sound.We tried to solve it using different techniques like the setup,video source,function keys pressed on remote control by trial(only assumed) and error as we could not see the screen and I used scart with every conection but three point pin was free so I put only one pin in video out put and at that moment I could see the picture on tv.
