Question about Televison & Video

2 Answers

TV quits working, screen goes black and red light next to power green light flashes 4 quick flashes . After a second or two of no flashing,red light repeats "code" flash. We pull the power plug at the TV, and the TV may start and work fine, or it may run for as short a time as 15 seconds. The remote cannot be used during this time while red light is flashing. Just before the warranty was up we had to take this TV in because the screen had verticle lines but sound was ok. The so called "mother board was replaced.This new problem started after the 3 month warranty period was up. Is the flashing light a code that will assist in evaluating repair.

Here are some helpful tips you need to consider as follow
1.) Vertical line at the left of the picture
Replace L506 on A board, replacement part number 1-407-366-0
2.) White vertical line only displayed on tube
Check for dry joint or burnt track on Horizontal Yoke PCB socket or main board
3.) Vertical lines are not straight when picture is very bright or has white text content
Replace resistor 3420 in the beam current circuit (12k or 15k) replaced with an 18k

Please let me know any update.

The Sony diagnostic routine for 4 blinks indicates it to be a vertical deflection problem.

Did you see a solid horizontal line in the center of the screen prior to it going out? If so, that is a tell tale sign for vertical problems.

basic sony reset below

The STANDBY light will flash if the television detects an issue within the television. Some of these issues can be resolved simply by following the steps below to reset the television.

  1. Turn off the television. IMPORTANT: For a projection television that uses an internal lamp, wait 5 minutes after turning off the television to allow the lamp to cool before continuing with the following steps.
  2. Unplug the television power cord from the electrical outlet.
  3. Let the television remain without power for 60 seconds.
  4. Plug the power cord back into the electrical outlet. NOTE: If the television is plugged into a power strip or surge protector, remove it from the power strip or surge protector and plug it directly into the wall outlet. If the issue is resolved, the problem is with the power strip or surge protector and not the television.
  5. Turn on the television.

If the issue is still unresolved after following all of the troubleshooting steps, service may be required. Please note the number of times the STANDBY light flashes and relay that information to the service center

    Sorry no simple fix, sounds to me related to original issue, although you say warranty is out you may be able to get it fixed as a recall on originial line problem. good luck

    This should be treated as a recall on vertical line problem, I suggest you protest and complain that fact to repairer.

Trying to replace lamp in HDTV and having trouble. Does not function correctly after putting in new bulb. Boots up and then visuals go black and the green power light keeps flashing. Help?


Panasonic DLP TV Bulbs

Make sure its an original Osram or Philips bulb inside the housing. If its a cheap lamp it will act this way. If it is an original lamp, then you may have a power supply issue. It shouldn't affect your TV but you may want to try resetting the lamp timer by following the instructions that came with the lamp.

TY-LA1001 Timer reset

While pressing the VOL- button on the projection display, hold down the number 0 button on the remote control at the same time for more than 5 seconds.

Samsung HLP4674W - changed bulb - still no picture - lights flash


If the lamp has been replaced I would think the Lamp ballast would be most likliest followed by the color wheel and then the Digital board. You can get any part needed for your model at www.tvrepairworld.com just leave them a email they respond quickly.

Olevia Kolin PT-501 LCOS TV Screen remains black and lights flutuate


I have the same TV and had the exact same problem. I had to replace the lamp and power supply in mine to get it to work. Unfortunately...its next to impossible to find the parts, at least the power supply. I found the lamp online and I was lucky to get the online store I purchased the TV from to send me a power supply from one of thier stocked models, but only after I turned them into the FTC Consumer Protection. The TV was sold to me as a closeout but new, as it turned out the tv was a refurb, thats the only way I could get the parts I needed.

Hope this helps and if you need any other information please let me know.
