I have a Panasonic CT-36hL43G TV that just turned offf while watching it and now the led by the power button blinks one time. Can anyone tell me what this code means or what the problem might be?


i hope your tv is more than 4years old ....... in all CRT TV's or CRT monitors after 4years a component called flyback transformer (see picture ) becomes weak - its work is to supply voltage to tube............. then following are the signs ...
(1) in some TV's only front LED's blinks - no picture no sound.... (2) in some TV's picture comes slowly after few seconds or after few mins or after few hours......... (3) in some TV's suddenly picture & sound goes temporarly & after some time again it appears ...... etc in case of (2) & (3) only flyback transformer needs to be replaced .....100% GUARANTEE again TV works normallyBUT in case of (1)... --------------- YOUR CASE (a) either only flyback transformer gets deffective or (b) flyback transformer & another component called transister ( will be near flyback transformer & its back portion is attached to aluminium metal ) gets defective or (c) along with flyback & transistor -- 3 or 4 more components (resistors, diodes, some times ICs ) gets deffective so replacing flyback transistor is a must .. & to find whether any other component is deffective or not completemainboard has to be checked ....... so if you are a technical person & having expierence in servicing line then you can do it yourself otherwise approach good tv service engineer ........... your TV is really very good one ... so don't think of buying new TV .... just goahead for repairing it it is worth & it works for atleast 2 more yrs....... try this & tell me what happened switch off your TV ... remove power cord from socket ,,,,.ware some mat or chapples to your feet ..... remove your TV's back side cover ......... observe carefully for any physically damaged components .... if you find then don't do anything ... close tv cover & approach tv service engineer ............. but if no physically damaged components are visible then take a suitable screew driver & rotate 2 (or 3) Knobs on flyback transformer in clockwise or anticlockwise direction - very little ( 4 or 5 degrees ) - you have to do this without touching any cable or any part of your tv .......... then fix..... back side TV cover ........connect power cord - stay at a distance & switch on your tv ......... if you get picture atleast for few seconds then in your case only flyback transformer needs to be replaced otherwise complete mainboard has to be checked. to find other deffective component ............. so your tv problem is a harware problem - it cannot be solved using remote control or any buttons on your tv ..... if you are finding difficult to get it repaired then you can remove your tv mainboard with the help of some technician & send to me ...... i will replace deffective components .... & send back to you ....you only have to bare the shipping charges .....it will take maximum 12days (5days - to recieve + 2 days servicing + 5 days to send back to you )....

No picture but i have sound on my RCA F32676SB 32"


You do an adjustment on the screen nob on the flyback transformer?Resolders the CRT-(tv tube) YOKE wires R,G,B connections to the main PCB board?Resolders the video board CRT-(tv tube)video board pins sockets that connect the video board and the CRT-(tv tube) together.

Panasonic TV - no picture, but sound is ok


resolder flyback transformer contacts on the board, if doesn't help, replace flyback and horizontal output transistor

Hello,
The Horizontal Output transistor needs to be changed as it is most likely shorted. The current transistor on this set is a 2SD3402 (no longer available) it's new replacement part number is the 2SC5902.
Order 2 2SC5902 Horiz Output transistors.Replace the transistor by it self once and if all is ok then fine.
If not replace it again and also the the Flyback HV transformer. The HOT transistor is probably shorted again and the transformer is causing it.

Usually the horizontal output does become shorted when the flyback goes. I would replace the H output as it only cost around 3 dollars. You can check it with an ohms meter out of circuit to determine if it is indeed shorted or open.

27 inch tube tv won't stay on


You have a problem is in your horizontal section which also is part of your power supply. The high pitched whine is from the Intergrated High voltage transformer (also called the flyback transformer). This sound occurs when the freuency of the transformer changes and or the voltage gets too high. The click occurs as a result of the drawing of excessive current by the HOT Horizontal output transistor. This is repairable, but requires the correct equipment and a schematic.
