When I was a TV engineer back in the early 1980's there was a lot more smokers around. I was a workshop based apprentice and had to clean and service the sets. I remember spraying Ambersil Foam cleaner on them and watching the smoke tar slide down the screen, leaving a brown puddle on the bench. Lovely. They stunk too.

It reminded me of a rental set we had at a customer's house . The chap smoked continuously.I cleaned the tube and a few months on the wife died of lung cancer when it was the chap that smoked. Absolutely tragic

2:47 Serial number appears to be LB-8151272. That indicates: Factory: MELUK (Pentwyn, Cardiff). Assembly line: B Build details: 1’272nd set of the first week of February 1988. The symbol on the front cover of the service manual is the lower case Greek letter Alpha. As previously stated, this model used the Alpha 1w chassis. The ‘w’ denotes this as the 110’ version against the 90’ used in the smaller screen models, (the Alpha 1 chassis made its debut in the truly awful TX1).

I remember fixing a TV like this, well fixing was to clean the filthy black screen when the customer went out to make some tea and when they returned the they had a lovel bright sharp image again and they over the moon. Those old 80's and 90's Panasonic TVs were so reliable, one of the few TVs that didn't constantly suffer from failed mains switches *cough Ferguson/Tatung cough

Wow that is one filthy set, I have repaired a few pub TV's back in the day, always hated that brown sticky gunge from years of exposure to tobacco smoke, the original owner is probably deceased after smoking 60 a day! As a boy I was given a 1950's set because the owner thought the tube had gone, turned out that both the safety glass & CRT face were so filthy from years of smoking & living in a room with an open coal fire, that set had a nice bright picture when properly cleaned 🤣

10:00 The ‘fusible resistor’ you mentioned was a zero Ohms device in the supply to the frame output chip. It was cheaper than using a normal fuse and could be fitted in production by the robotic ‘pick and place’ machines, along with the majority of the other components. These fuses had a high failure rate in the early models, and this was usually, and not unreasonably blamed on the frame output chip, although that was actually seldom the cause. In fact the cause was usually a left handed person. There was a large (grounded), heat sink that ran front-to-back of the board, roughly in the middle. Tabs formed on the bottom of that heat sink passed through slots in the board and were twisted, by someone on the line, using pliers, so as to keep the heatsink in place as it made its way down the production line. Right beside one of those slots was a copper track on the PCB, which was between the fuse and the frame chip. A left handed person would twist the tab in the opposite direction from a right handed person, and in this case the tab would be twisted over that track. If the tab then penetrated the varnish on the PCB and contacted the copper of the track it would short the track to ground and cause the fuse to fail. This was almost NEVER a solid fault making it very difficult to identify. On later versions of this chassis the tab was still present but was no longer twisted in production, and that measure practically stopped the problem, aside from the few occasions when the chip had actually failed of course.

Excellent Micheal. Panasonic TC2475 used to remind me of the Grunidig CUC70 having the similar looking scan coils. The models TC2205 and TC2206 were also very good units. I can remember the Panasonic TC2206 that used the CRT tube A56-540X (30AX). This tube was nearly used in all the CRT TVs at the time (Apart from Sony). You had Ferguson and Philips that used it quite a lot for their sets. Philips G11 used the A51-540X (20AX). There used to be a red capacitor in the power supply of the Philips G11 that had to be changed to a blue capacitor which used to save the tube, otherwise if the red cap was still in unit the tube would blow out. This was a error by Philips which was later announced to engineers...

🚬📺 I would not put this thing in my house, not even in the workshop! Eeww. I have one in similar condition, I repaired it outdoors in the yard, then put it in an outdoors shed for 10 years to ventilate. It is a 14" Beijing color TV. Those Chinese sets are amazingly reliable. Mine was never repaired before (maybe apart from some capacitors replaced), but it has a ton of hours in it. All it needed to work again was a bunch of capacitors and resoldering. If I know this right, these were licensed from Toshiba, earlier ones had Toshiba tube and ICs in them. Mine is later, only the flyback is Japanese in it, the tube is branded either "Sunshine" or "Rainbow", all the ICs and capacitors are Chinese, yet it somehow survived 30 years of use and it still has a good picture.
