I have the same problem. rca 26lb30rqd. The red light is on (steady), and when I hit the power button, the blue light comes on for a second, then goes black, w/ no display. Before this happened, the display was extremely bright with ghosting. The picture was un-viewable. Did you every figure out the problem?

unplug the television...wait 10 seconds and then plug back in....if you listen carefully after 5-10 seconds you will hear a click sound (the same sound that you hear when you turn on or off) ...once you have heard it, turn the TV on again using the remote. Do not turn on until you hear the click. If this does not work, try again but turn the TV on again before you hear the click. I dont know why it happens but it is as if the TV gets confused as to whether its supposed to be on or off. Most of the time, the solution is to turn it on after the click so I would always try that first.

My Sony trinitron has the stero lite on steady and standby lite flashes four times then pauses and repeats. Can you tell me the circuit/condition causing the set to not turn on.

Hold Down The Power Button For 20 Seconds
You Will Hear A Few Beeps But Don't Let Go Until You See A Picture

most times then not it's the capacitors on your power board that blew there for not supplying the tv with enough power if you open it up and check the capacitors it should be leaking some kind of liquid or the tops have bubbled up. its an easy fix cost>>2 dollars each

Solved by resoldering some solder joints!!!!!!!

Toshiba Model 57H81 Rear Projection TV - Purchased 11-09-2001

Problem: Toshiba 57H81 Flashing Red Power Light, No Picture/Sound, Blown Fuses F850 + F852

Symptoms January, 2009:

• Upon turning on set I got flashing red power light and nothing else.
• Removing plug for one minute and plugging in results in:
• Audible click, steady red power light for 2 seconds then slow flashing red light
• Pushing power button results in steady red for about 2 seconds then slow flashing red light, no other set activity
• Removing power cord for several hours and plugging back in made no change
• Audible click, steady red for about 2 seconds then slow flashing red light
• Possible related note: Over past several months occasionally the entire screen would flicker momentarily and at other times be problem free for weeks.
• Fuses F850 and F852 found blown

Repairs Made:

• PD0074 DEF/CON Power Board
• There are two main power supply capacitors in this set. They are C-809 and C-810. One their negative lead on the printed circuit board re-soldered leads and nearby contacts. I’m told that because the factory left out a printed circuit board eyelet, the connection will come loose over time. When I called Toshiba customer service they said there was a known solder joint problem causing blinking red light.
• Replaced blown fuses F850 and F852.
• I actually installed a fuse panel on the inside of the cabinet and routed the fuse connections here instead of ordering the special fuses and replacing them on the circuit board.
• Had to use a 5 Amp SLO-BLOW for F850. Fast blow does not survive power up. Get the red blinking light.
• Used a fast blow 2 Amp for F852.
• PD0073 SIGNAL Board
• Re-soldered Q751 + Q752 STK392-110 Convergence Amps
• Re-soldered adjacent pads that looks suspicious

Total Cost to Repair about $10

• Twelve hours of my time over three days to research issue, disassemble set, make repairs, add fuse panel.
• Already owned Service Manual and Circuit diagrams from a different 2004 repair.
• Less than ten dollars at Radio Shack for fuses and fuse panel. Already had wires, etc.
• Some solder. Already owned de-soldering tools, etc.
• Visited both local authorized Toshiba factory service repair facilities. One said repair would have to include replacing Q751 + Q752 STK392-110 Convergence Amps with ST392-180, and realigning set for a total of $500+ and it would be more if they had to order a power board. NO THANK YOU! Other shop said $65 for site visit and $30 to make an estimate that could be applied to repair.
