    Similar problem with our Toshiba. Power surge apparently cooked power supply unit, estimate for repair is $350 from a shop here in San Diego. Doesn't that seem a bit high? How much could the power supply cost? Could it be replaced/repaired by a novice (me)?



    Thanks,

    Bill

This set is pretty common for the regulator IC to go bad. Its inside on the power supply Printed circuit boad assy. It will start with STR#### and have 4 digits after the STR####, depending on the model of the set. Good Luck

TV turning off and on and stays black


Fault at its main digital board. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts.

In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.
Before going further; try a hard reset first. If it does not help you, replace the main digital board. There are two methods to reset TVs. The first is simple to do; a Hard Reset. The other is somewhat skilled; is a Factory Reset (System Reset). To make it a hard reset, just unplug the TV from AC mains wall socket, and re-plug it back after 15 minutes or so. If you do this by overnight is better. This procedure will make it a hard reset. If you want to make it a system reset [Factory Reset]; you have to enter its service mode option, and select the factory reset option. If you wish to get some details; visit the site linked here

I have a 58'' HP Pavillion Projection screen TV. It was struck by lightning. the power cord is good. It will not turn on at all, no fans running, etc. What do you think I will have to fix?


As u have just said that it was struck by lightning the only way to get the TV back working is to replace burnt items on the moterboard .becouse lightning must have demaged some components on the power supply, if possible i would preffer a new power supply board

Struck by lightning and won't power up


WOW!
Warranty voider there.
Hate to see a $1,000 TV go down the toilet.
If your lucky, you can try checking the fuses inside the TV.
The lightning may have taking out only your power supply board, shopjimmy.com may have replacements for about $100. But, I can't tell you for sure that will fix the problem.
You may have to take to a repair shop to find out for sure.
Good Luck
