Question about Hitachi 50V720 Television

Lights flashing and no piture or sound

I purchased my TV in 10/2006. I'm having the same problem. Last night there was a loud pop and the screen went black. Now power light, temp and lamp light are flashing. Owner's Manual says that the optic unit has an air filter may be clogged and need cleaning. Anyone know how to get to the air filter?

    I have a similar problem, and no maual to look at!

    Same problem: a pop, then flashing lights and darkness. I quickly found in the manual that the problem is the bulb, but the manual I have is for the 825 series which apparently has a very simple lamp replacement from the outside of the unit.



    I don't see any external way to access the lamp on the 720. How do you replace the lamp? A new lamp appears to be about $160 on-line. Any better deals out there?

My tv is three years old just replaced the lamp 2 months ago. i picked my lamp up from a supplier off ebay, very trusting guy. puresupply is the guy. i think i paid $110 for the lamp. just the lamp. when replacing the lamp the gray plastic cover under the power button pops off. the lamp is located left front side of the tv. it takes 5 minuets to replace for anybody. one last thingwhen putting your mew lamp in if it does not fit don;t panic. there are som shims that is in that housing, remove the shims then put the lamp back in the housing. it should fit perfect. for those who need a manual send me a message at lewis.cleveland@pgnmail.com or buck115taz@yahoo.com

I had the same problem a little over a year ago. It was the lamp. It needed to be replaced. I hope you have the extended warranty.

Hello, Last night my Samsung plasma TV made a fairly loud popping sound while I was watching it and then the power went off. When I turned back it on, no picture but sound was o.k.


Yes the caps on theower supply, but you can check power supply board by smell an look for burnt parts it is common. May need more than one board if they are cheap get both.

Last night our TV made a loud popping noise then the picture went out. We still have sound but have trouble turning the TV off. What could this be and is it fixable? Thanks, Anne Marie Orcutt


Hi,
Question shows it is Vizio L32 lcd tv and symptom shows back light inverter board for defective for some reason and loud noise would be popping of any chip on inverter board.
Shopjimmy..com has replacement boards of that model on reasonable price and local tv repairman will replace defective board after checking/ testing the tv.
Hope these info will help.
Thanks.

I have a 60" Sony


Hi,
It seems lamp/ bulb popped again, check lamp inside tv.
If tv does not show red blinking light then it would be lamp that knocked off, replace lamp in tv to fix its problem, please buy Sony original lamp for good picture in tv.
Let me know if you have additional question.
Thanks.

Sounds like the DLP lamp failed. You can decipher the Hitachi flashing red light. That should help to be sure.
The DLP lamp replacement is fairly straightforward and can be done with minimal tools

I have a SONY WEGA flat screen, last night while watching tv, there was a loud pop in the tv, now the LAMP light keeps flashing and there is a grinding sound coming from in the set. No Picture, no other...


The loud pop was a capacitor blowing.

The light is flashing because either power board or ballast board is faulty.

Using the TV in this conditions can cause further damage.

If under warranty contact the manufacturer ringing the number on the user manual

If you want to repair at your own expenses, just locate any good qualified repairer.
