Hello
Your Samsung tV is LCD type. It has no bulb to replace as in DLP projection televisions. there is CCFL [Cold Cathode Flourocent Lamps] are the lighting devices, which are fitted just behind the LCD screen There will be more than 12 numbers of them, accroding to screen size. If these lamps do not light up; that is; if you do not get any backlight with your LCD TV, the backlight inverter board should be troubleshooted. This is the board that supplies high frequency high voltage to these lamps to light up. Check this inverter baord first. Repalcing backlight CCFL lamps is really a skilled work, as they are fitted inside the panel, and to replace them, you have to disassable the panel itself.

61 inch projection tv flashing on and off


The most common problem with JVC LCD rear projection TV is bulb failure. Do not panic, this is normal after 2-5 years of use.

You can change the complete assembly or for less cost just change the bulb. Do not use Osram or other funny brand "rebuilt" or locally made bulb. Use a Philips replacement and all should be good.

Changing the bulb involves removing the lamp assembly and taking it apart like a puzzle and replacing the bulb. JVC are a little more difficult to do than most others because the wires on the original bulb are molded into the glass on the original bulb. Wires must be cut and stripped of insulation before connecting to the new bulb.

All JVC LCD Rear projections TVs use TSCL110 TSCL110U TS-CL110U Lamps.

Should I change the bulb?


Hi MovieJunkie9,

I would first recommend having a diagnosis done by a Toshiba authorized technician. Bulbs for projection televisions are typically a costly part, so I would not advise replacing it if you are not sure it is needed.

Second, make sure that your product's manual lists the bulb as a user-serviceable part and gives specific instructions for you to change the bulb to make sure you do not do any damage to your unit.

So long as your manual gives you instructions for changing your bulb and the Toshiba authorized technician diagnoses that the bulb is the issue, you should be able to go ahead and change the bulb yourself.

Thank you,
Jason,
Go Ahead. Use Us.
