Question about Hitachi 53FDX01B 53" Rear Projection Television

1 Answer

Lightning strike Lost picture and sound. All leds on power board are lit. led is lit on big board where the secondary power feeds in. The led next to the high voltage coil doesn't light. Was wondering if the strike hit the antenna input and fed through the back door, or went through the power supply. one voltage reading is -38 volts were the block diagram says should be +39. Should I purchase a schematic fo $20 or is there a site with free downloads? Don't know where to find a test point on the secondary power supply. Old TVs used to say the voltages on the boards where test points were.

I have a LED TV that was hit with a power surge caused by lightning.


Could be your household insurance would cover the damage.

Unless the lightning strike was very local to you, on your side of the local substation, the responsibility for the cost of repair or replacement could be the power company's.

Surges from lightning strikes aren't supposed to get past the electrical substation.

Old-fashioned valve tvs and radios sometimes survived huge surges on the powerline and even minor lightning strikes to the antenna but solid state semi-conductors and micro chips aren't very tolerant to overloads of any sort. These days a tv is not longer a tv in the conventional sense but like cars and radios should be considered as just another computer that is full of CMOS chips which are extremely sensitive to overloads and static discharges. Even the screen of your tv is made up of semi-conductors.

I would be very surprised if the set isn't a write-off.

Toshiba 37AV500U damaged thru HDMI input.


The lightning stroke has been effected to the main digital board to your TV. It will be best to replace the main digital board as card basis, rather than trying to repair it. Before replacing the board, a through checkup should be done. Contact any expereienced service technician for help, as this work is a very skilled one. No body can predict about the damages to a lightning stroke, as there will be trillions of voltage present for every stroke, and even a slightest voltage can damage so many components in a TV like equipment, as it is designed to work for 110 or 220VAC.

No Picture & No sound. Red LED, Green LED, Red LED.


If the power supply outputs are good! Then I would say the back light inverter is bad! If the screen stays black and does not come on.

DP23 LED not lit on deflection board no picture on tv


Good Day, Gil;
Your problem is in deflection circuit (115+v) check these: FP05, DP15, Q777, QH01, TH01, T701, etc. BUT suspect C707 1k pfd, 2kv, and check all the pico fuses (brown) 2" to the right of cap. Good Luck, big IRISH.

Does not power on. Q951 charred


you can look for the model and brand, look for it on the internet and see if you can have the schematic diagram, you're lucky if u can. Lightning will strike first the tuner side, if there is a red blink, the primary side may be okay in switching type regulator, just replacing the charred part may not solve the problem. look for shorted components on the secondary of the power section.
