SOURCE: i have picture but no sound on my 42 inch vizio

If you received a remanufactured board it might be defective,Or did you forget to hook back up the speakers? Sounds dumb but happens alot. Speaker wires get in the way,we disconnect them to look at a board or replace one.Often gets over looked.But I have received several defective boards.Hope this helps. Toddthetvmd

I have a 52" Mitsubishi Lt-52244 TV which has sound, no picture but has images with the flashlight test. Which board/s should I replace?

That is an older model set that still has the backlight inverters. It may be one of those and it may be the power unit. Mitsubishi LT 52244 TV Parts

LCD TV diplays blue screen on all inputs

Nothing on all inputs would suggest the Main AV board not processing signals, if all other functions such as volume, menu access, on and off operate normally the power supply board is probably functioning OK.

Green Blinking light on Mitsubishi Unisen lt 40164, tv wont turn on?

Hi Since that did not work, The next thing is you have to take the back off the TV and find the main power board. On that board there will be some bad capacitors. Look for bulged or leaking CAP(s).
Replace them with same capacitors types. If you're not tech. savy Go to TV repairman. Good luck.

Try unplugging for 1 minute, then plug back in again. It appears that the unit is initializing, if it continues in that mode you may need the DM PCB

How munch would it cost to fix my Mitsubishi TV - 52" Flat Panel TV: Model LT-52244.??? My kid hit and broke chip it.

Depends on the damage, your problem is vaque.

Best Buy, Radioshack both send off items for repair.

Find a local tv shop, if they fix it for less than $200 i'd be surprised.

depending on damage location, and severity i estimate $200-$800

Sound works no picture

The most likely the TV has a power supply related problem. The most common thing to go out is the circuit board that supply power to the screen. Commonly called a Backlight Inverter Board.
I can't say it's 100% the problem because I can't actually look at the tv over the internet.
If the TV is still under warranty, go that route.
If not under warranty and If you have some electronic experience, you can purchase a Service Manual over the internet and diagnose the source of the problem and fix it by soldering in the new part. The Service Manual will give you circuit diagrams, test points, and part# lists. Usually, cost under $20.

I hope I shed some light on the subject for you.
